I read about a developer saying it doesn't work, "and probably never will". Why is this? The two OSes aren't that radically different, I think.


The answer is given in a mailing list comment by Stefan Dösinger entitled Wine 64 bit

OSX has a ABI incompatibility with Win64 - OSX overwrites a CPU register that Win64 applications expect to remain untouched. Apple can’t change the ABI because there are already 64 bit OSX apps that expect things to work that way. A potential workaround may be to run Wine inside a CPU emulator like qemu, but that is anything but easy.


Wine on macOS can run 64-bit applications since version 2.0. Here are the release notes for 2.0

The main highlights are the support for Microsoft Office 2013, and the 64-bit support on macOS.

  • Why was this downvoted? Also how the heck did they manage to do that given the previous explanation of why it is not possible?

  • @psusi I guess Apple must have made a change to their operating system making it possible Jan 28 '17 at 13:47
