Re: [B2-devel] TESyncScrap (Thoughts on SheepShaver and Basilisk II)

[C.W. B. <com...@ho...>]

Just to clarify, you can run 32-bit apps under a 64-bit kernel under OS X. For instance, I have Skype running on my 64-bit kernel Lion installation and that is only 32-bit right now. You can't run 32-bit Kernel Extensions on a 64-bit kernel, though. The reverse is also true: You can run 64-bit apps on a 32-bit Mac kernel (If you have a 64-bit processor). My server, a 2007 Mac mini is unable to boot into 64-bit kernel mode but still runs 64-bit programs just fine.
