For starters, the iMac Core Duo uses a Low Voltage Differential Signaling (LVDS) interface -- a low noise, low power, low amplitude method for high-speed data transfer -- for transmitting data to the computer's 17- or 20- inch LCD display.

Though the new iMac looks remarkably similar to the iMac G5 with iSight announced late last year, one way to differentiate the two models is to look for the presence of a mini-DVI output port featured only on the iMac Core Duo. This new DVI out port will allow users to choose between video mirroring or extended desktop (with an added Apple DVI Display Adapter).

The iMac Core Duo is reportedly the first iMac to support Apple's extended desktop feature, which lets users extend their viewing capabilities by using two or more displays at the same time. With this functionality, users can choose to view a single document or application across multiple displays, or use each display to view a different document or application.

Like the previous iMac, the iMac Core Duo sports a built in iSight, which sources say uses a CMOS sensor with a fixed-focus plastic lens rather than a CCD sensor with automatic focus like the one used in Apple's stand-alone iSight product.

Sources also report that support for AirPort Extreme and Bluetooth in the new iMacs is achieved through separate cards instead of a single a combo card used by Apple in the past. Antennas for the wireless technologies are mounted at the top of the iMac enclosure -- the Bluetooth one on the left side and AirPort Extreme on the right.

True to reports making the rounds on the Web, the first Intel Macs use EFI (Extensible Firmware Interface) -- essentially an updated BIOS specification that allows vendors to create operating-system-independent device drivers that are stored within the hardware itself. The EFI BIOS is also used to select and load the operating system when the computers first starts up.

The iMac Core Duo's Boot Manager -- accessible by holding the option key at startup -- also features some slight interface improvements, sources say, but for the most part remains visually unpleasant. The systems also include a NVRAM (Non-Volatile RAM) as opposed to a PRAM (Parameter RAM) and a SMC (System Management Control) as opposed to a PMU (Power Management Unit). The NVRAM is still resettable by using the Command-Option-P-R key combo.

Each new iMac Core Duo appears to be shipping with Mac OS X 10.4.4 for Intel build 8G1165, which does not include support for the Mac OS 9 Classic environment.

Very impressive overall. Take note however: No Classic mode. The end is near!

Some Pics with good detail of the new Duo imac. Have to say, this looks like a home-built machine compared to the first two G5 imacs that were easy to take apart. They are as clean inside as the G5 tower. Check out this mess:


As ugly inside as a low end Dell...maybe worse. :mad:

I know they were moving fast to get these out, and did a great job schedule wise, but the last rev G5 imac looked about the same inside. Not sure what this means. Speed and features are going up (overall) at the same price, but I can't say I like the trend....

01-14-2006, 02:27 PM
Of the many more or less impportant applications that won't be usable anymore as they most possibly won't run on Rosetta are the various device drivers e.g. for GDI printers, scanners and so on. Which is why Classic is dead and impossible.

Suddenly, people that bought Intel Macs will find out they can't scan and print anymore. Most drivers for scanners and GDI printers are written in carbon, and judging from the transition to Mac OS X, I doubt that Canon, Epson, HP and the like will be in a hurry to re-write their drivers.

This would take at least one year (it took over six months for HP to get a DeskWriter driver for to work with OS 7's VM). Most PostScript printers will operate though, but the vast majority of Inkjet won't -- except if you are lucky enough to have a gimp driver (which is usually not true for the newest printers).

Another application with dire immediate future is Skype, I suspect this is another candidate which probably won't run under Rosetta (it might be that its CODEC is written partly in PPC assembly language). There is no word on Skype's web site on Universal Binaries... But we will soon find out from the brave early adopters.

Kernel extensions Kernel extensions are not support on the Intel version of Mac OS X, and applications that rely on kernel extensions will either not run or exhibit significant issues.

Preference Panes Applications that install preference panes or reply on them will not work with the Intel version of Mac OS X.

01-20-2006, 10:27 AM
Wow. That seems to be a huge shift. Wonder if it is an architectural change, or simply not supported yet, and will change with later OS releases? Hope so.

Plenty of good little apps that live in the Preference Pane, including stuff from Unsanity, Sophos AV, Norton AV, SharePoints Adobe VersionCue....must be dozens more.

This has been mentioned now for days (week?) on MacFixit:

Intel-based Macs: Slow network connections (#4): Terminal-based workaround
We continue to report on inordinately slow network operation exhibited by some Intel-based Macs.

We first reported on very slow connection and volume mounting times for Intel-based macs connecting to Xserves over AFP (Apple filesharing protocol), and later indicated significant slowdown when attempting to connect Intel-based Macs to networked PowerPC-based Macs.

Terminal-based workaround We've now identified a solution to the slowdown issue that involves modifying the delayed_ack parameter of Mac OS X's TCP/IP configuration by entering the following command in the Terminal (located in Applications/Utilities):

sudo -w sysctl inet.tcp.delayed_ack=0

This is one of the settings enacted by Apple's Broadband Tuner for FiOS connections, but has proven effective for reducing throughput bottlenecks on Intel-based Macs.

The Delayed ACK timer is set when TCP receives data that must be acknowledged, but need not be acknowledged immediately.

The inet.tcp.delayed_ack parameter is default 1, which means the host computer waits too long before sending the next packet, where in fact it can already send the next packet.

The problem with this workaround is that after rebooting your Mac the parameter is reset again. So in order to make the change permanent, you need to add the aforementioned line to the /etc/rc file.

You can open the /etc/rc file in the text editor vi with the following command:

sudo vi /etc/rc

After this file is opened in vi, enter sudo -w sysctl inet.tcp.delayed_ack=0 right before the 'exit 0' at the end.

"I just switched from Windows XP to the new Intel iMac. Both machines were connected through 100 Mbps switched ethernet, so why the transfer was so slow (< 1 Mbps)?

"Changing the delay_ack to '0' immediately improved the transfer between my Windows XP and iMac (up to 65 Mbps). Where I had mapped an iMac folder on the Windows XP machine, and dragging files from Windows to that folder."

Why Adobe Has No Universal Binaries
Linked by Thom Holwerda on 2006-03-24 16:18:38 UTC, submitted by mono

"By now you have probably figured out that we aren't releasing Universal Binaries of our current application versions. If you haven't, all you need to know is pretty explicitly spelled out here [.pdf]. 'But, c'mon', I hear people saying, 'Steve said it was just a recompile!' Or, 'Back during the PowerPC transition, you guys released a patch!' Well, this time is different. And I really wish it weren't."

Intel CPU Mac problems with AppleJack 1.4.2
"AppleJack 1.4.2 is broken on Intel Macs

From www.xlr8yourmac.com today:

The process completes disk repair without issue, but will hang on permissions repair, offering an error message that the computer cannot find it's name. (I always skip that step, and don't use the automatic feature.)

I had to force a reboot. Thereafter, some Finder Menu items fail to load during startup.
"Yes, unfortunately it appears that the subsystem tools that AppleJack hooks into to perform its tasks are either incompatible with the flags I'm throwing them from bash, or they are simply not as robust on the Intel platform as they are on Power PC.

I have a hard time believing it's a problem with the Intel version of zsh (the default single user mode environment), or with bash (the shell language AppleJack is written in).

I will try to take some time this weekend to post this to the AppleJack sites.

As it looks, since there is no information from Apple on how to work with or program anything in single user mode, I am strongly considering just stopping development of AppleJack. With every version of Mac OS X something becomes less stable or predictable, and there is, as I said, absolutely no documentation from Apple on how to use the tools they provide in single user mode. I think they'd rather people just stay away, and to this overworked developer, its working.

If there are people out there with the skill set and patience to develop AppleJack further, I would like to speak with them. At the moment I have no Intel Mac to test it on (I only own one macintosh, and that's an old iBook g4).

Intel will significantly cut the price of its Core Duo/Solo CPUs on Mat 28th.

The Merom processors, produced on 65 nanometre process technology, will have 4MB of cache, support 64-bitness and virtualisation, while the low voltage versions will have 800MHz buses, eventually.

The Core Solo CPU currently used in the mac mini entry level model might simply disappear by the end of May. A new high-end Core Duo CPU should be introduced with a 2.33GHz clock speed.

Universal Binary Goals

We produce universal binaries by building PowerPC bits using gcc 3.3 and the 10.2.8 SDK, and merging them with Intel bits generated with gcc 4.0 and the 10.4u SDK. The differences in compilers and SDKs accounts for the need to run on PowerPC under versions of Mac OS X earlier than 10.3.9. The universal merge is handled by a script that runs lipo on executable code.


A prerelease build of Firefox is available as a universal binary. It contains all x86 and universal fixes and should be fully functional.

The Intel Mac work for Firefox, Thunderbird, and Camino is largely done.

ntel to release 2.33GHz Core Duo
Followed by price cuts
posted 1:40pm EST Thu Apr 13 2006 - submitted by Ronnie Lindsay

All you Intel Geeks who are planning to buy Core Duo-based machines anytime soon may want to read this first:

Intel is slated to introduce new speed bins of the chip within the next 6 weeks, and will follow that move with additional price cuts to spur demand. The newest SKU will boast a clock speed of 2.33GHz per core, still sharing a 2 MB cache. The chip will still be 32-bit, until the Merom processor comes out in Q3.

The processor will likely soon after be found in Apple and Dell notebooks alike. The new release will drop predecessor chips down a price level, with the 2.16GHz chip taking a price cut of over US$200 to sell at $423. I'm guessing that if you're buying these, you really don't care about 64-bit, or Merom for that matter. Otherwise, patient Geeks are likely to wait and see what Intel has in store for Q3.

Radeon X1600 in MacBook Pro and iMacs are massively under-clocked

Apple dramatically underclocked the GPU of its notebook models. Indeed the Radeon X1600 in the MBPro is clocked a 310MHz / 278MHz (GPU and RAM respectively) Many PC notebooks featuring this GPU have a 470MHz/470MHz setting...

Apple's default speed for the 20" (intel) iMac (X1600) is 400/400. ATITool told him the max was 540/594. Running at 515/575 is rock solid.

Seagate SATA 7200.9 owner Drive Firmware Versions -

"I have been told by Seagate that firmware prior to 3.AAH does not work properly in Macs. This is the cause of the 90 second delay when waking from sleep. Seagate had me return the drive under warranty for replacement with a drive containing the latest firmware.

The firmware update that they sent me was 3.AAH. I was unable to perform the update so I can't confirm that it fixes the problem.

The easy way to tell if it is the same problem is to look in the system.log file using Console. After waking, the log will show the following repeated about every 11 seconds until the drive responds:

kernel[0]: IOATAController device blocking bus.

A similar spinup/ready delay after waking from sleep was reported by a Maxtor (500GB IIRC) owner also a month or so ago. Similar problems were mentioned by an Intel CPU iMac owner with a WD Raptor 150GB.

The successor to the GMA 950 used in the current MacMinis.

Source : PC Inpact

Apple's choice of using the GMA 950 video for the Mac mini has not been a popular one. Although it is price is low, its performance is even lower.
According to an internal document discovered by HKEPC, its successor, the G65, could very well change that.

It will utilize standards, such as OpenGL hardware acceleration, H.264 hardware playback, and hardware post-processing effects utilising 32 bit precision and even anti-aliasing. A far cry from a true video card, but passable.

The next revision of the Mac mini cannot get here soon enough!

One of the Mac minis weakest points is its 2.5'' HD, with noticably slower performance than a 3.5''.

It's still possible to partially compensate for this using a fast external HD, yet if output increases, so does latency. The page http://www.artmac.info displays a daring yet efficient mod of a Mac mini Core duo. Once the internal drive is dismantled, a SATA connector was put in the machine to plug an external SATA drive.

One can even imagine plugging a SATA port mutliplier (see today's other news) hence transforming the Mac mini into a very efficient server with as many as 5 drives.

Plug 5 Drives on a SATA Port

Addonics is shipping the 5X1 eSATA Port Multiplier (PM) (AD5SAPM-E) for $85. Addonics 5X1 (http://www.addonics.com/products/host_controller/ad5sapm-e.asp) AMUG Review Addonics 5X1 eSATA Port Multiplier (http://www.amug.org/amug-web/html/amug/reviews/articles/addonics/5x1/) allows connecting 5 Serial ATA drives on a single connector.

AMUG's tests confirm there's a problem with the latest PCI-Express G5s. The SATA transfers either via the integrated ports or an additional card are still 10% behind those of PCI-X G5s.

Adam Levine has posted some tests of a 8 Drive SATA II RAID0 system using a PMG5 PCIe equipped with a Sonnet e4P and Port Multiplier:

Robert Garcia flagged a potential source of MacBook Pro network problems:

I manage a bank of servers, and noticed that the MacBook uses the Marvell chip. I have seen nothing but problems with these and have replaced all my server NICs with Intel Pro, and no issues.

I was having serious network problems with my 15" and my server and realized my server was also using the Marvell chip... I had connected the server with the wrong port. Changed my server to use the Intel Pro port, and now my 15" and 17" work just fine on my network.

These Marvell chips are popping up everywhere, and I can't tell you how many network issues I have seen with them, hanging and disconnecting.

New Intel chipset fuels Mac speculation Macworld UK reports that Intel has launched a new chipset for desktop computers today, which will work with forthcoming new processors that are likely to feature in Apple's next-generation pro desktops. "The P965 Express chipset, formerly code-named Broadwater, will work with Intel's new Core 2 Duo desktop processor, also known as Conroe, which is due to go on sale next month. The chipset has started shipping in volume to PC makers already, Intel said." More.

Apple pushing Intel in new directions ComputerWorld reports that one year after Apple Computer announced plans to use Intel processors in its computers, Apple is pushing the world's largest chip maker into new directions, a top executive said Monday. "They push us to think about things that we may not always think about," said Anand Chandrasekher, senior vice president and general manager of Intel's sales and marketing group. "We were hoping for that to happen and that certainly happened," he said. More.

MacBook Pro - Resetting Power Management

Shut down.
Close lid.
Take out battery.
Disconnect powercord.

And -- with NOTHING connected, press and hold POWER ON button for 5 seconds.

There is no sound or any indication this does anything.

Windows XP Performance on a Mac Linked by Thom Holwerda (http://www.osnews.com/editor.php?editors_id=11) on 2006-06-25 21:35:28 UTC"[We] can easily enjoy the best of both the Mac and Windows XP worlds on a single system--as long as that system is an Intel Mac. Apple's own Boot Camp Public Beta allows you to install Windows XP SP2 onto an Intel Mac, giving you a dual-boot system. Parallels takes a slightly different approach with its Parallels Desktop for Mac, a virtual machine application. CNET Labs ran a few of its home-brewed benchmarks (http://reviews.cnet.com/4531-10921_7-6546370.html) on a MacBook Pro with the Mac OS, Boot Camp, and Parallels Desktop to see how application performance stacks up between the three."

Core Multiplexing = Threading Hardware

It seems that Intel is ready to fire back to any AMD technology innovations, even to the Threading Hardware system we jsut mentionedyesterday (http://www.hardmac.com/news/2006-06-26/#5661).

According to Xtremesystems (http://www.xtremesystems.org/forums/showthread.php?t=104178), Intel is ready to launch its own Threading Hardware solution, named Core Multiplexing. It seems the technology is already implemented in the Core 2 Duo and could simply be activated via a firmware update.

So in the future, non optimized applications will benefit from multicore CPU, even though it will never be as fast as a multicore-aware version of the same application. So this technology might be important for already existing applications, but developers should always try to get the best out of multicore CPU, especially Pro applications.

Without much emphasis, Intel has added 2 new models to its Core Duo offer: the T2700 clocked at 2.33GHz. Its retail price is 637$ (for 1000 ordered units).

The second new model is a ULV Core duo, a.k.a. U2500 ULV, clocked at 1.2GHz; that would be perfect to power an ultra-portable notebook.

Intel to launch dual-core Itanium 2 CPUs on July 18

Shawn Chen, Taipei; Jessie Shen,
DigiTimes.com [Friday 30 June 2006]

Intel plans to add its dual-core Itanium 2 CPU line, dubbed "Montecito," to to its current Xeon 5100 series (codenamed Woodcrest) and Dempsey processor offerings on July 18, according to sources at Taiwan server makers.

The dual-core "Montecito" processor line will feature more advanced specifications for the high-end market, compared to the "Woodcrest" seres under the new Intel Core microarchitecture (65-80W in power consumption) and the "Dempsey" under the NetBurst microarchitecture (95-130W in power consumption), indicated the sources.

To make an external bootable hard drive with both HFS+ and NTFS file systems, do the following.

First use Disk utility to partition the drive. Make the first partition HFS+ and the second partition as MS-DOS (FAT32), making sure you go into 'Options...' and check the GUID radio button (to make the HFS+ partition bootable on Intel). Then follow these steps to complete the process:

Connect the hard drive to a Windows machine, and wait for the FAT32 partition to mount.

Open My Computer and right-click the FAT32 partition and select Format.
Format the partition with an NTFS filesystem.

Remove the drive from the Windows machine, connect it to an Intel Mac, and install a disk image built for Intel Macs.

Windows Applications On Mac, Without Windows

CodeWeavers has announced that CrossOver Mac will be arriving this year in late July or early August 2006. Pricing will be at $59.95 for single-user licenses, with volume and educational discounts available. CrossOver Mac will support a number of Windows applications to run natively within Mac OS X using Wine, enabling the user to run Windows applications without having a copy of Windows installed on their system.

Codeweaver's solution differs from solutions like Apple's Boot Camp and Parallels Desktop in that it does not require a copy of Windows to run the Windows applications. Also, applications will be able to run side by side with their Mac OS X counterparts

Intel intends to extend its current lead in performance desktop computers and said that it will launch its quad-core processors ("Kentsfield" on the desktop and "Clovertown" on the volume server side) already in the fourth quarter of this year.

Kentsfield consists of two Conroe cores and should enable Intel to reach fairly high yields by the end of the year. The same applies to Clovertown which is created from two Woodcrest cores.

Intel has launched the Xeon 5100 processor based on the new Core architecture in June and will follow up with the desktop (Conroe) and mobile (Merom) version in the coming weeks.

According to chief executive Otellini, Core 2 Duo is "ramping as rapidly as possible" and Intel claims that it already has built a Conroe inventory "that is worth about $200 million."

Conroe, or Core 2 Duo (http://www.anandtech.com/mb/showdoc.aspx?i=2797)

CNet News.com reported yesterday afternoon that Intel's quad-core desktop chip (Kentsfield) and Xeon-class chip (Cloverton) have been bumped up and should arrive before year's end.

Intel is shipping Core 2 Duo Mobile chips (Merom) to manufacturers, according to recent Intel financial report (http://www.macrumors.com/c.php?u=http%3A%2F%2Fdownload.intel.com%2Fintel%2F finance%2Fearnings%2FIntelQ22006earningsfoils.pdf&t=1153508239).

At first attributed to bad RAM, but it now appears that other causes are at play, or corrupting some plist files.

Possible software-based workaround Although the majority of sudden shutdown cases appear to be due to problematic hardware, a handful of readers are reporting success with software-based workarounds.

In particular, some users are finding success with a workaround we've suggested for various wake-from-seep and related issues -- deletion of the following files:


This workaround may need to be repeated from time to time as these files can become corrupt with some frequency. - MacFixit

2007 Intel Santa Rosa chipset should remove effective 3 GB RAM limit on some Macs

Core 2 Duo-based MacBook Pro (Late 2006) can physically accommodate two 2 GB RAM modules for a total of 4 GB, Apple's specs list the model as able to recognize a maximum of 3 GB of RAM. The same limitation applies to Apple's Core 2 Duo-based iMacs.

The 3 GB spec results from Apple's attempt to protect users against purchasing memory that will not be usable by their systems.

Current Core 2 Duo-based Macs (MacBook Pro, iMac) share a chipset that -- while capable of carrying 4 GB of RAM -- can recognize and make use of only slightly more than 3 GB. This is because the currently used chipset assigns to critical system functions and components (the PCI bus, etc) a ~700 MB chunk of memory space in the 3-4 GB memory range that cannot be used by the operating system.

Note: Apple's documentation [MacBook Pro or iMac developer notes] does not specify which chipset is used in its Core 2 Duo Macs. However, the chipsets used in currently shipping MacBook Pros and iMacs are in the Intel 945 series.

In systems with less than 3 GB of RAM, the occupation of this space is trivial -- no physical RAM exists there, so the devices happily occupy an otherwise empty range. In systems with more than about 3.3 GB of RAM, a conflict arises.

The Intel 945 chipset is 32-bit. A 32-bit processor/chipset can address a maximum 4 GB of RAM, so the motherboard is built to accept only 4 GB. However, all system functions have registers that occupy mapped memory space. Many of these functions occupy tiny portions of space -- 4 KB for the Memory Control Hub MMIO, for instance. Some take significantly larger portions: The PCI Express Register Range occupies 256 MB. In aggregate, these items use about 700 MB of memory space -- yielding the ~3.3 GB ceiling for OS-addressable RAM.

Speculation holds that this limitation will be overcome when the Core 2 Duo (Merom) gets a chipset better suited for its 64-bit capabilities, and with a memory addressing scheme that does not require virtual space for system functions/components between 3 GB and 4 GB.

This more apt chipset should show up in the first half of 2007, and holds the moniker Santa Rosa.

Santa Rosa will be the chipset for which the Core 2 Duo (Merom) was designed (the 945 chipset is better suited to the original Core Duo, but can accept the Core 2 Duo as well). It eliminates the ~3 GB memory cap, and more importantly, sports the capability to access memory in the 64-bit range, opening the door for portables that can carry 8 or 16 GB of RAM (or more), power considerations aside.

According to Intel's press materials, Santa Rosa will also provide: "an improved graphics chipset, codenamed Crestline, an IEEE* 802.11n WiFi adapter, codenamed Kedron, as well as Inteloptimized advanced management and security solutions. The platform will also include Intel's NAND flashbased platform accelerator, codenamed Robson, which enables much more rapid bootup time and power savings"

First (beta) look (http://www.kungfooo.com/2006/11/04/ubuntu-610-vmware-fusion-mac-intel/)

* Updated Version

I managed to get my hands on a private beta of the brand spanking new VMware for Intel Macs earlier today, the following is the first (so I am aware) screenshot tour of the boot / install process for Ubuntu 6.10, inside VMware Fusion on a MacBook Pro (Core Duo, 2GHz 1024MB RAM).

Penryn Core 2 Duo Processors (http://www.macrumors.com/2007/07/17/intels-upcoming-penryn-core-2-duo-processors/)

Dailytech.com claims (http://www.macrumors.com/c.php?u=http%3A%2F%2Fwww.dailytech.com%2FMobile%2B Intel%2BPenryn%2BCore%2B2%2BDuos%2BRevealed%2Farti cle8067.htm&t=1184760902) to have more leaked information -- this time on Intel's upcoming Penryn-based Core 2 Duo Processors which are due in Q1 2008.

The upcoming Core 2 Duo processors will continue to use the 800MHz FSB ranging from 2.1GHz to 2.6GHz with up to 6MB of L2 Cache on the top end models. Meanwhile a Core 2 Extreme revision will top out at 2.8 GHz. Penryn is expected to bring a number of enhancements (http://www.macrumors.com/2007/04/17/intels-penryn-chip-boosts-speeds/) and performance enhancements (http://www.macrumors.com/2007/04/17/intels-penryn-chip-boosts-speeds/).

The Santa Rosa spec will be revised to support the Penryn-based mobile Core 2 Duo processors which are due in Q1'08. After this release , Intel plans on overhauling their mobile platform in Q2'2008 with the "Montevina" revision.

Apple recently took advantage (http://www.macrumors.com/2007/06/05/apple-releases-new-macbook-pros-with-santa-rosa/) of the Santa Rosa chipset in new MacBook Pros released in June 2007. Apple would be expected to take advantage of the upcoming chipsets around their release in Q1 2008. In the meanwhile, Apple is expected (http://www.macrumors.com/2007/07/10/ultra-thin-and-ultra-light-mac-notebook-in-2007/) to release a Ultra-thin version of the MacBook Pro later this year.

2008: Intel's upcoming 45nm "Penryn" processors should give the company some extra horsepower to combat AMD's Barcelona and Phenom X4 processors in the coming quarters. According to a report by DigiTimes, Penryn will also enable Intel to make even smaller and more power-efficient chips (http://www.digitimes.com/NewsShow/MailHome.asp?datePublish=2007/7/17&pages=PD&seq=212) for low-power systems.

In the second half of 2008, the site says, Intel will introduce two low-power versions of Penryn: an LV version and an ULV version, both with ball-grid-array packaging.

Update: It looks like the sizes quoted by DigiTimes are not die sizes as the site says but package sizes. The upcoming LV and ULV Penryn models should therefore have package sizes of 22mm x 22mm.

Apple refreshes iMac lineup

MacWorld: Apple updated its iMac line (http://www.macworld.com/news/2007/08/07/imac/index.php), beefing up the systems with Radeon HD 2400 XT and 2600 Pro graphics and Core 2 Duo processors between 2.0 and 2.8GHz. These upgrades come wrapped in a new aluminum and glass enclosure that eschews the sterile whiteness of previous iMac designs. The systems will also come with a new keyboard that's significantly thinner than previous Apple designs.

All three systems come with 1GB of memory and an 8X SuperDrive.
A 2.8GHz Core 2 Duo will apparently only be available as a configuration option.

In Apple's press release for the iMac, they make a small note that the Airport Extreme has been updated to include gigabit ethernet. Apple's 802.11n Airport Extreme base station had only included 10/100 Base-T ethernet, which had been a sore-spot in reviews considering all Macs now ship with Gigabit ethernet, and the theoretical wireless performance would outstrip the wired performance.

iMac Software Update 1.0 appears to be graphics-releated

Though Apple's cryptic release notes don't indicate so, it appears that iMac Software Update 1.0, which applies to the Mid-2007 iMacs released earlier this week, contains revisions to various graphics card-related components.

Among the files modified by the update:


* ATIRadeonX2000GLDriver.bundle
* ATIRadeonX2000VADriver.bundle
* ATIRadeonX2000GA.plugin
* ATIRadeonX2000.kext
* ATINDRV.kext


* GLEngine.bundle

So essentially, various files for driving the ATI Radeon X2000 card available for the new iMacs and an OpenGL-related bundle file were revised. It's still not clear, however, what graphics bugs were fixed or performance enhancements made.

AMD graphics driver hole opens Vista to rootkits
by Cyril Kowaliski - 09:56 am, August 10, 2007

A proof-of-concept tool put together by a ReactOS kernel developer Alex Ionescu has unmasked a serious vulnerability in AMD's graphics drivers for Windows Vista. As ZDNet reports, the security hole allows the Vista kernel to be patched to turn off "certain checks for signed drivers." Through this vulnerability, a malicious programmer could develop software capable of bypassing the mandatory driver signing mechanism in Windows Vista x64 in order to load a rootkit—a tool designed to conceal the operation of other malicious software—onto the operating system.

Ionescu says he released his "Purple Pill" proof of concept without knowing that the flaw in AMD's graphics drivers had not yet been patched. Roughly an hour and 20 minutes after realizing his mistake, Ionescu pulled the proof of concept. However, the file had already been downloaded 39 times. When asked about the security hole, a Microsoft spokesman told ZDNet, "Microsoft is in contact with ATI to help address this issue and once fixed we will assist in getting it to our customers."
