Question

I recently upgraded my Macbook Pro to SL OS 10.6.8 and now have pink lines around the desktop borders and some menus. There is also a horrible red colour that appears in the background of photobooth and parts of Safari. The screen saver looks like an alien life form with red in the background. There are odd translucent colours in the background of other applications including MS Office. It looks like a horrible psychedilic trip from the 60's. I ran the upgrade again but nothing changed. Can you help?

Backup your files off the computer (not TimeMachine) and disconnect.
Hold c boot off the 10.6 disk, under the Utilities menu > Disk Utiltiy > Repair Disk, and Repair Permissions
(quit and stop if Disk Repair (only) issues a failure and notify us)
Quit and install 10.6 again, reboot and Software Update again,  this time download it and then run it. Check Software Update until clear.
c boot off the 10.6 disk and use Disk Utility >Repair Disk again (fixes a bug)
Reboot and check any installed programs, some may not function who have installed kext files into OS X, those need to be reinstalled.
You didn't mention if you upgraded from 10.5 or 10.6.7, the above steps are for fixing a 10.6 to 10.6.8
If you upgraded from 10.5, you should erase the drive in Disk Utility first, then install 10.6 fresh, but then all your programs will have to be reinstalled or updated from original sources.
Also the 10.6.3 upgrade disk has no free iLife, but you can install 10.5 fresh then upgrade to 10.6.3, then to 10.6.8 and then all new programs and that will give free iLife that came on the factory 10.5 disks.
You also can use Pacifist to extract iLife from 10.5 disks.
