Might not be the perfect forum for the question, but I know many Mac gurus frequent it, so I’m asking it anyway
When I ship a 64-bit application that only targets Mac OS X 10.7 and newer, is it guaranteed to work on every Mac that runs OS X 10.7 or newer?
In other words, do Macs exist out there that run 10.7 or newer but are 32-bit only? From my research, even if you start OS X with the 32-bit kernel, it can still run 64-bit applications. My worry is whether there are Macs out there with 32-bit-only CPUs that cannot do that.
