    Default No OS X Recovery Partition Missing

    Hi. I have a Mac Pro Mid 2010 model Quad-Core w/38 GB of memory. I want to completely wipe it clean and install a new OS before I get rid of it. However, when I restart holding down the Command R buttons it does not reboot in the Recovery partition. When I check in Terminal I don't see it either. Below is what I see. As a side-note but it may be relevant, whenever I boot up my computer I get a message "The disk you inserted was not readable by this computer". At one time my computer crashed and I replaced the bay drive with the external Bootable HD (a Seagate Barracuda I think) I was using as my backup. What is the best course of action?:

    If you ever cloned your boot drive, you will not have a Recovery partition. Recovery is built when a clean install is done.

    The fix, since Apple took OS installers out of App Store, is to call Apple and ask for an iTunes (yup, in iTunes) link to the appropriate installer and download - flush - install clean.

    Thanks, Rick!! You answered a question nobody thought would be an obvious inclusion when writing an article on what to do when Recovery partition doesn't work. How the heck does one "call" Apple? LOL. It's tough enough to get a response via email. So, the trick I just read of holding down Option/Command/R to use Internet Recovery I'm also going to try.

    I called Apple and got an installer just a few weeks ago. I was selling a 2010 MacPro and wanted a clean install. No longer is the installer in my App Store. So I opened a chat and asked. Here's the chat:

    Thanks for contacting Apple Support. My name is Mya. Please give me a moment to look over your information.

    Hello Rick, I hope you are doing well today!

    Hi Mya. I am trying to reinstall HIgh Sierra. In the past, all OS I had downloaded and installed were listed in App Store. However, nothing is listed there past Yosemite. How do I locate the install Mac OS download?

    Mya
    I am happy to help! That software isnít found in the App Store, funny enough. Here is a link to get it: How to upgrade to macOS High Sierra

    Here is a direct link too: https://itunes.apple.com/us/app/maco...741?ls=1&mt=12

    Thank you.

    Mya
    My pleasure! Would you like me to standby to make sure you can access it?
