Mac OS X On the Wine mailing list, there is some interesting information on Leopard's apparent ability to load basic Windows binaries. "When tracking down a crash in the kernel32 loader test, Dmitry found a bug in the Mac OS loader when Wine tried to load his dummy PE file. Upon further research I found that the Mac loader seems to have its own undocumented PE loader built in. I did some further testing with a Windows binary and got some really interesting results." The first thought was that this was a remnant from Mac OS X' EFI support, but upon further investigation, this really seems like new, Leopard-specific behaviour: "This is new to Leopard. On Tiger, dlopen rejects PE files as expected. The Wine testing that Steven was originally trying to do would probably not crash on Tiger." Apparently, Apple is trying its best to hide this behaviour.

Member since:

"Should have" and "could have" are two very different things, though.

They should have done this years ago, and they definitely could have done it. Wine has been around for a very long time, notwithstanding the fact that they will only have feasibly been able to possibly run Win32 binaries without some emulator with their move to Intel.

This is why there's nothing going on here. If Windows compatibility was important to Apple they would have got into it years ago.
