10.6.8 Supplemental Update (10.6.8 v1.1)

This is a minor update to 10.6.8 released in the last day or two.

If you are already running 10.6.8, you can safely install this update without re-patching for your HD 5870 or 5770.

If you need information about updating to 10.6.8 from another OS X version, running a 5770 or 5870 ATI graphics card, see the article here.

New version of 10.6.8 patch

It turns out the original patch, while fixing the drivers for the 5770 and 5870, caused some problems for the older ATI cards, most notably the 2600XT, which some people have running alongside 5xxx series cards.

The new patch keeps your older ATI cards running as well.

Update: The ability to install to a separate volume has been added, so you can run the patch installer from 10.6.7 with your 10.6.8 drive as the destination.

You can find the new patch here.

For installation instructions, see the original post.

If you’d like to uninstall the patch for any reason, here is the uninstaller package.

Tips for Recovering 10.6.8 for 5770/5870

Special notes for those who have already upgraded to 10.6.8 and have lost display functionality

If you still have access to a display (most cards still have DVI/VGA functionality), simply install the patch to your boot volume and restart.

Get the new 5xxxDriverPatch here.

In the case of a card that won’t boot (this seems to be the case for some 5770 cards), or if you depend on DisplayPort for your display, here are some recovery options:

1. Use another video card (remove the 5770) to boot 10.6.8 and install the patch.

2. If you have another mac boot drive or can create one, you run the patch from the other drive with your original drive as the destination.

3. If you have a monitor that supports analog, try booting in safe mode (boot with the shift key held down) with only the VGA display plugged in. You’ll be using the DVI-VGA adapter (on the DVI port closest to the CPU tray on the 5770 standard, DVI port farther from the motherboard on the 5770 single slot). Once booted in safe mode, install the patch and restart normally.

10.6.8 without breaking your 5770/5870

How to Upgrade to 10.6.8 without breaking the 5770/5870 video drivers

Unfortunately the 10.6.8 update completely disables some 5770 video cards, and disables the DisplayPort on other 5770 cards and 5870 cards.

If you have already upgraded to 10.6.8 and have lost display functionality, please see this article.

There is a patch that fixes the broken drivers in 10.6.8. The trick is to install the patch after installing 10.6.8 but before restarting the computer to apply the update. If you restart and complete the 10.6.8 before installing the patch, you may find yourself with no display. Read on for details.

Warning: Follow this procedure at your own risk! The smart thing to do is to fully back up your 10.6.7 boot volume before proceeding.

1. Instead of updating to 10.6.8 via Software Update, download the 10.6.8 installer from Apple here. (This installer assumes you have 10.6.7 already installed. If you have 10.6.6 installed, you can download the 10.6.8 combo from Apple here.)

2. Run the installer, but when the installer finishes, DO NOT CLICK RESTART. Before restarting your machine, run the 5xxxDriverPatch. After installing the patch, you can safely restart.

Get the newest 5xxxDriverPatch here. (The new patch keeps older ATI cards like the 2600xt working, see the release notes, also you can now install the patch from a different volume.)
