You can often get away with a 32-bit OS, particularly if you boot it in BIOS/CSM/legacy mode but a 64-bit version gives you greater flexibility and may enable an EFI-mode boot, especially for Linux. Let's take the easy one first: A 2011 Mac would have a 64-bit EFI, so that means you should install 64-bit versions of all your OSes on it. ![]() Is there any hope at all that I could run Mac OS X 10.10 (Yosemite) on this system?

I then tried to re-install Snow Leopard from the DVD, but the installer insists that the “Macintosh HD partition cannot be used for boot.” If I inserted the Snow Leopard disk, I could boot Mac OS X from the hard drive. It still boots fine into Linux, but trying to boot Mac OS X it fails to find the boot loader. ![]() Pretty sure that the Fedora install screwed up the EFI partition. Fedora came up, and now I cannot boot Mac OS X. Shrank the Mac OS X partition and installed Fedora (21) from DVD.
