MXO with Nvidia or ATI? What you need to know.

[Matrox_Support_Mac]

For MXO users, please take note of the following:
- For ATI graphic card users, make sure to upgrade to Snow Leopard 10.6 or 10.6.1 only. ATI graphic cards will not work under Snow Leopard 10.6.2 and MXO 2.1.5 beta drivers or 2.1.6 drivers.
- For Nvidia graphic card users, you will need to upgrade to Snow Leopard 10.6.2.
Note: For ATI users who are already in Snow Leopard 10.6.2, you will need to revert back to Snow Leopard 10.6 or 10.6.1.
Please contact Apple support for instructions on how to do this.

Here are the individual Snow Leopard updates:
Snow Leopard 10.6.1 (for ATI users) - http://www.apple.com/downloads/macosx/apple/macosx_updates/macosxv1061update.html
Snow Leopard 10.6.2 (for Nvidia users) - http://www.apple.com/downloads/macosx/apple/macosx_updates/macosxv1062update.html

Important: This software is provided as is. We recommend that you back up your system before installing new software and we do not recommend that you update your MXO software if you're in the middle of a project.
