i was running 10.4.9 on my quicksilver G4 until yesterday when i decided to run the update since i needed it for some software and fixes. now it wont start up most of the time and has causes a ton of problems. first, my transparent dock is gone. second, my sound card (m-audio revolution 7.1) now doesnt work properly as the sound is fuzzy when i play music. i even tried to reintall the drivers but then i got NO SOUND and the analog out was disabled in sound preferences. i uninstalled the drivers and am left with no sound now. its been giving me kernel panics and tells me to restart when i try to boot up. also the apple is huge as well as the restart box (looks like its on a 640x480 monitor). when i started up, the time was gone and my internet didnt work. the network preferences didnt even allow me to check built-in ethernet. i restarted and now everything works again *knock on wood*. is there any way i can go back to 10.4.9? also, how well does 10.5 work on PPCs? would my dual 1 GHz G4 run slower with it?
