Greetings all, I'd really appreciate some suggestions. I have a Macbook, running 10.5.2, and it seems that since I updated to the aforementioned release, I'm having all kinds of problems with software downloads. More specifically, I've been trying for over a week to download Parallels 5584, I've tried via the Parallels software update process and by going directly to their download link. When I try to execute the file, I always get invalid checksum. Tonight, I just tried to download the latest release of Itunes, same type of problem, a week back I tried to do software update for the graphics update, it took many many tries, it finally downloaded, not via software update but via a link at Apples website. So, any suggestions would be most appreciated. I should mention that I've done a repair disk permissions and that didn't help. Thanks for any suggestions.
