I haven't been able to find this issue anywhere in all of my searching...
Since installing Leopard on my Summer 2006 MacBook (both Upgrade & Install and later Erase & Install) I experience random periods of what I can only describe as "Loss of Write Permission to Any Disk." I cannot save files, empty the trash, write to a flash drive, print, sync my e-mail, etc. I can do things like browse the Internet via Safari, however upon restart any website that I visited does not show up in history... it is as if I never went there.
At first I thought it was just an issue with the fact that I upgraded from 10.4 to 10.5, then after the Erase & Install I decided my HDD was going bad until I found that I couldn't write to a Flash Drive either. Any ideas?
No... Repair Disk Permissions didn't do me any good either.
