    Default High Sierra won't install on SATA

    Hello.

    I installed High Sierra on my Mac Mini (SSD), no bother.

    As my partner was still running El Capitan on her MacBook Pro (old, but upgraded to a 1TB SSD a year or two back), I thought I'd upgrade her machine too, just so we were on the same page.

    When I got to the install button, the machine told me it couldn't install on 'this type of drive'.

    Any ideas why, or any ideas as to a work-round?

    Thanks.

    Allen.

    It could be the type of SSD or the connection type, but I'm guessing it's the age of the computer, plus the newer OS. What model is it?

    Hello Yeungfeng.

    It's:

    MacBook Pro aluminium 15 inch late 2008
    2.4Ghz Intel Core 2 duo
    Memory 6Gb
    Serial W89063QH1G0
    Drive 1tb SATA

    Probably a Toshiba SATA - that's what my local company often fits.

    Allen.

    Latest supported operating system is 10.11 on that model Mac. The firmware check won't allow Sierra or newer to install.

    That would account for it. Thanks Riks.

    Hey Rick, just a thought. If one took the SSD out and loaded it with High Sierra and reinstalled the SSD, would it boot? I have read that you can do that for 2009 model iMacs.

    No idea any longer. Can certainly try it.
