10.5: VMware Fusion, ATI video cards, and 10.5.7 Apps
If you're using VMware Fusion to run virtual Windows OSes with 3D graphics enabled, and you're doing so on a Mac equipped with an ATI video card, you'll want to hold off on updating to OS X 10.5.7, if you haven't done so as of yet. (The following problem does not affect Nvidia-equipped Macs running 10.5.7.)

I got word from VMware last night that OS X 10.5.7 breaks the 3D acceleration in Windows virtual machines, but only on ATI-equipped Macs. According to VMware's blog entry on the problem, when you try to use 3D acceleration on such machines running 10.5.7, you will "likely see issues ranging from slow performance, to incorrect rendering, and even crashes."

According to the blog post, both Apple and ATI are aware of the problem, and are working to correct it. In the interim, though, the only solution is a non-solution: disable 3D acceleration (in the Display section of the virtual machine's Settings panel). If you require 3D acceleration for your Windows apps, it seems you'll have to use Boot Camp until Apple, ATI, and VMware get this one fixed.

Anybody know if this affects Parallels as well (not that Parallels 4 has ever worked properly)?

You could try VirtualBox, Sun's free competitor to Fusion and Parallels. It works very well for me and it's a free download at

10.5: Parallels + 3D works with 10.5.7

Yes rpaege, Parallels does not have this problem. We tested 3D functionality with Parallels Desktop for Mac and saw no such problems. More information in this blog post:
