Your options are limited to the following
emulation:
wine/crossover
Virtualization:
Parallels/VMware/Virtualbox
Native windows
BootCamp
The latter two require a copy of windows, while wine/crossover does not. Performance of wine/crossover is the worst of the three types. Games and such are best suited for bootcamp. Not all apps run under wine/crossover but most do under vmware (other then some games)
First off, Wine =/= Emulator. WINE actually stands for WINE Is Not an Emulator. Its is wrapper that converts Window API calls to *nix calls. If anything, its an interpreter.
Second off, WINE and Crossover Games are no where near the worst in performance. It all depends on what you are using them for. Try running Guild Wars on High in a VM and in Crossover and tell me which is worse. WINE/Crossover use native hardware, not virtual, to power the apps it runs, so it is much more powerful then a VM. The only issues with WINE/Crossover are compatibility issues hence why there is an application compatibility database on both CodeWeaver's and WINE's sites. I have tried a few games not even listed on Crossover's site and they worked fine (Example: With a little tweaking, I was able to get Megaten Online: Imagine working almost 100% in Crossover Games when it first came out, months before CodeWeaver added it to their compatibility listings).
Anyway, I agree that Crossover (costs money but has better support then WINE) is your best bet for getting Windows Binaries running on an Intel Mac. It all depends on what apps you are going to use though. I use Crossover Games for a few games I play randomly (Guild Wars, Megaten Imagine, Steam) and a Win7 VM for any non-graphic-intense apps and games that will not run in Crossover (Indie Windows Games, Homebrew tools for DS and PSP, etc.)
Depending on what you are trying to run DOSBox might be something to consider. I haven't tested it fully yet (but plan to so I can play some Decent 2; Can't find Mac PPC version anywhere), but I have heard good things about it. Heck, even read somewhere (think it was here) that someone got Windows 3.1 to run it.
CrossOver looks pretty sweet!
I don't have much interest in running MS Office thanks to iWork, but i would be interested in running Windows Live Messenger to video chat with non iChat buddies.
It's not listed as 'officially supported' - does anyone here have experience with this?
Live Messenger is listed on
CodeWeaver's compatibility database and
WINE's AppDB as a Bronze and Silver grade app (depending on version).
BTW, If an application is not listed in CodeWeaver's compatibility database, check out WINE's. Since Crossover is just a professorially tweaked version of WINE, any apps that run in WINE
should run in CrossOver. Also, any tips to make said app work in WINE should also work in CrossOver.
I love crossover but, i was working fine. Then i opened it then later it kept saying shutting down and it will quit of the blue moon. Everytime i open it. Can anyone help?! please really appreiciate it thnxs a bunch.
Have you upgraded to the newest version of CrossOver? I had a similar issue that was fixed after upgrading. Also, would email CodeWeaver about it. They provide free tech support for CrossOver users.
