I've recently been having a LOT of problems with my MBP freezing. I was wondering if anyone else has had similar problems? I'm running a early 2008 MBP with OSX 10.5.7. I use time machine and have bootcamp installed too. I've been looking around for similar problems but the things I've tried haven't worked and it's getting REALLY frustrating. It happens probably 55% of the time I use the computer now and it feels like when it's doing something like loading a webpage and asked to start say, msn, it will just give up and stop responding. I cannot for quit either, the shortcut won't work and when I try to do it from the dock, it freezes too. So any tips would be greatly appreciated. My PC crashed so often I knew what to try to fix it, but my mac has always been so good, now that it's giving me grief I have no clue how to track down the problem. Thanks a lot, Chris Edit: Safari is an example - my MBP seems to freeze at random times in any program or sometimes even just after start up and I click an app in the dock.
