VMware, makers of Fusion, has warned their users away from installing Mac OS X 10.5.7 if they have a Mac using an ATI graphics card or chip.

Fusion enables Intel-based Macs to operate other operating systems like Windows and Linux without having to be rebooted first. The “virtualisation” software is a popular alternative to Boot Camp and Parallels Desktop.

The message, posted to the “Team Fusion” blog on the VMware Web site, states that Mac OS X 10.5.7, released Tuesday, will break the 3D graphics acceleration feature supported by Fusion — it enables gamers and others running 3D software to use their products in a Fusion virtualised environment.

“You will likely see issues ranging from slow performance, to incorrect rendering, and even crashes, when you run your 3D applications in a Windows virtual machine on Mac OS X 10.5.7,” reads the blog.

“Both Apple and ATI are aware of this problem and are working to correct it in a future software update. In the meantime, if you have an ATI graphics card in your Mac and need VMware Fusion’s 3D features to work, we recommend that you do not upgrade to Mac OS X 10.5.7,” the entry concludes.
