I have some problems with my mac. 1) After the update before last, my screen ended up tinted blue. Some other people got this too. The people at the apple support line got me to do a system re-install thing. I forget what it was called... but it re-installed OS X, it kept my files, etc. It did ****-all. For another week it was tinted blue, then it stopped. The only thing is, now I've lost like 12 GB if space just because of these people who made me hold for 23 minutes and basically through 12 GB of my Hard drive out the window. I have a 2.0 GHz MacBook. So obviously I want to undo what I did, keep my files (FOR SURE. no 'probablies ' How do I do that? 2) OS X always thinks the iSight is being used. Always. I click on Photo Booth, and it tells me 'Photo Booth cannot open because the camera is in use by another application'. The problem is, ITS NOT. This happens when I have programs open. This happens when I have just restarted, and its the first thing I open. It happens in the other user account. It happens in my test account. Ideas? Thank you all so much in advance.
