I got my first Mac, a late 2008 MBP, last week. For the past couple days, most of my programs keep crashing. For example, when I opened iTunes last night, it crashed 4 times in a row, so I reinstalled it and it seemed to work fine. This morning I got a message that the mac software updater crashed (I had left it on over night). Why are my programs crashing more often than on Windows? What can I do?
