Jun 23, 2011 8:41 PM in response to Tazthedby Matthew Yohe,Just installed... Of note, there was this line in the install log:

Along with the ATISupport and ATIFramebuffer...

Jun 23, 2011 9:39 PM in response to Matthew Yoheby Eminemdrdre00,I just had my screen turn black and it froze 10.6.8 didn't fix the problem...back to the 10.6.2 kext files.

Jun 23, 2011 11:25 PM in response to Eminemdrdre00by Eminemdrdre00,Be careful... I got a kernal panic after installing the 10.6.2 kext files on 10.6.8. I just had to reinstall from my DVD, get the 10.6.7 combo update, and install the 10.6.2 kext files again. Let me know if you guys have any luck with 10.6.8 with our fix. I'm using the ATI2600 kext file.

Jun 24, 2011 12:33 AM in response to DazzaGby Tazthed,I installed the kext files on 10.6.7. I just updated to 10.6.8.
1) Do you know if I have to install the kext files again ?
2) And how do I see whether the kext files in the system now are from 10.6.7 or 10.6.8 ?

Jun 24, 2011 11:06 AM in response to Eminemdrdre00by morpho,Same here, the bug is still there (can be seen by just launching iTerm2 and watching its titlebar "flash" randomly) but the previous workaround causes a kernel panic on boot.
DO NOT (and I mean it: DO NOT) replace the kexts on 10.6.8.

Jun 24, 2011 11:57 AM in response to morphoby Harkaitz,By the way, I´m pretty sure that this will screw the kext compatibility on Lion

I just tried iTerm2 with 10.6.8, but the titlebar doesn't "flash" on mine.
Did you just update from 10.6.7 with the kext files to 10.6.8 or did you update to 10.6.8 from a version without the kext files trick ?

Jun 24, 2011 2:11 PM in response to Tazthedby morpho,@Tazthed:
The "flash" happened just after iTerm2 started up, the bar went a bit darker than usual and I could clearly see a bright square area around each window button. Then it reverted back to normal almost immediately.
As for the update, before installing the 10.6.8 Combo Update I took a full block-level backup with CCC (man, I owe the dev a beer. Or two), then I restored the ATI kexts shipped with 10.6.7 and applied the update. After booting I had the same exact problems, so I tried the usual switch to 10.6.2's kexts. I rebooted the system in verbose mode and I was greeted by a kernel panic in ATI2400Controller.kext.
20 minutes and a system restore later I was back on 10.6.7 with old kexts and rebuilding dyld cache

Okay thank you for the answer. I am on 10.6.8 now and I have not experienced any freezes (yet).
First, I was on 10.6.7 with the old kext files from 10.6.2. Yesterday I updated to 10.6.8 without touching the kext files. Today I still don't have any freezes.

Jun 24, 2011 5:41 PM in response to Tazthedby Eminemdrdre00,You'll experience a freeze soon, unfortunately. And now we can't even use our kext fix on 10.6.8. I REALLY hope Lion is free from this issue. If not, what do we do?

Jun 25, 2011 7:29 AM in response to Eminemdrdre00by nekosaur,Same issue here - had no graphics / freezing issues for 1 full day after updating to 10.6.8 with Combo update.
Waking iMac from sleep this morning triggered a full freeze with artifacts.
Installed the 10.6.2 ATI drivers using the kext tool (what is this, the 4th time I've done this?) and was greeted with a heart-stopping MAJOR Kernel Panic at reboot.
Obviously the OSX team has changed something significant with the drivers in 10.6.8 so that it breaks this process.
Had to roll back to 10.6, upgrade to 10.6.7, reinstall the 10.6.2 drivers and stay put.
Looks like this iMac is officially dead in my eyes. Will wait for a revision of the Mac Mini with a cinema dispay for my next machine.
Too bad - this iMac could have lasted for quite a few more years. How am I supposed to sell this thing with good concience knowing that if the next owner updates to 10.6.2+ it will be a brick?!?! There is nothing hardware-wise wrong with it, but installing the newest OS renders it completely unusable. Ugh. Thanks for nothing 10.6.

Jun 25, 2011 8:07 AM in response to nekosaurby jaycee1980,Precisely why my old iMac is now my girlfriends machine - running Windows 7, where it is perfectly usable and stable.
Apple, do you realise how stupid you have made yourselves look here. This is +1 for the Windows market. Well done.

Jun 25, 2011 12:00 PM in response to nekosaurby Eminemdrdre00,You summed it up perfectly. We know this isn't a hardware issue, there's a problem with the graphic drivers in 10.6.3+. My iMac runs great when I use the older drivers. It's got a 2.66ghz Core 2 Duo processor and 4GB of RAM. I shouldn't need to upgrade just because of a software bug. Is there anything we can do to have Apple fix this? We've all been dealing with this for over a year now. I'll be upgrading to Lion on day 1, but what if it has the same problem?

Jun 25, 2011 2:05 PM in response to DazzaGby Tardigrada,Looks like I could replace the ATI Radeon HD 2600 Pro with a NVIDIA GeForce 8800 GS. Could that solve the problem?
