Cindori had a fix right away when 10.6.3 came out -- was wondering if he or anyone else knows of a similar fix for the 10.6.4 update? I'd like to grab the update as soon as possible and don't want the same issues happening as before. I ran the update on a test machine, and same thing happened. No dual DVI and sluggish graphics. I did, however, try installing the KEXTs that fixed the issue last time, the ones Cindori uploaded, and it brought back dual DVI (yay) but graphics performance is horrendous. Exposé and dashboard flicker and lag like crazy, folders in the dock take forever to expand and display, etc. etc. If there is any sort of fix for this, I would be most grateful so I could update my main Mac Pro to 10.6.4. Thank you!
