    So Beta 4 made my iMac un-bootable last week, I'm stuck on my nearly 10 years old MBP.
    What I'd like to do is download Beta 5 on my MBP, make a bootable drive, and reinstall it on my iMac b/c Beta 4 cannot be reinstalled.
    The Mac App Store tells me my MBP is not compatible and won't even let me download the installer! Is there anything I can do!?

    Thanks !

    Why exactly do you want to do this? Just how far into "sketchy and unsupportable" are you trying to go?

    You could maybe torrent it, with the risks that implies, but you're already so far into unsupported territory you might as well just add that risk on top.

    Or get a copy on USB from a friend.

    I wouldn't torrent it, I'm a legit developer, but my MBP is too old to download it.
    I just want to reinstall it on my iMac, because with Beta 4 there's nothing at all that I can do to reinstall it.
    BTW I have a 27-in Late 2013, the install is perfect on my iMac.

    So here's what I did :
    - Downloaded the latest compatible version of my MPB, which is El Capitan
    - Made a bootable USB drive with my 32 GB USB Key
    - Created a 60 GB partition on my iMac using Disk Utility from Recovery Disk
    - Installed El Capitan on my iMac on the new partition using my bootable USB drive
    - From the new El Capitan, downloaded High Sierra Beta 5 and installed it

    Took me the whole evening, but I didn't lose any data :)
