There were certain 64-bit machines that couldn’t go to Yosemite because they could only run a 32-bit kernel and 32-bit EFI or had non-discrete GPUs that weren’t supported by 64-bit drivers. Hence you could well be able to run 64-bit Windows or another OS on a 2007 Mac, but not OS X. Obsolescence like that is just the lay of the land where Macs are concerned, made worse by the new yearly, hardware-dependent release cycles for OS X, now much as with iOS.
You can still buy Lion or Mountain Lion. You buy them from Apple’s archival inventory and get a download code that you can use on the MAS to fetch the installers. You have to call up Apple to make this happen, or possibly only use the web store and not the Apple Store app. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
