I just bought my first Apple in years in July and everything has been great until last week. I'm not sure what happened but all of a sudden applications have started to randomly quit on me and I have no idea what to do about it. I first noticed it when I tried to attach a file to an email using Mail and it just quit right there. It happens everytime. I also can't save file attachments people have sent me without it quiting. Safari will quit sometimes, Firefox does the same. Safari's history has vanished and it won't log any new websites I go to and after going to a few websites it will stop loading any and I have to switch to firefox. Just about any application I have used has randomly quit on me or frozen up since this started happening. I have even had the entire system freeze up several times which before I was extremely happy to have said hadn't happend to me once in the entire 3 months I had owned this computer. No, I'm not going to switch back to a PC, but as a mac newbie I have no idea where to go from here. Anyone else had this problem? Do I need to do a full system reinstall? If so, any tips on backing up files on the mac that I would want to save? Thanks!
