I'm sure the answer is pretty simple or has already been asked alot but I figured I'd open myself up with my basic help question at this time. I have an iMac20 and am still running OS Tiger. I know I'm basically very behind on upgrades but I haven't spent much time on the internet on my Apple computer. I mainly use it for composing music, iTunes or making movies but since I recently changed jobs, I no longer have use of a company laptop or office computers where I was doing most of my net surfing so now all of my internet work is being done on my iMac. Most recently, my Safari OS has been crashing alot. Not sure if it's because I'm using an old OS or if it's something else. Does anyone have any insight or experience with this? I'm not the most computer savvy person.
