I have only switched to Mac since May 20 2004 after getting a new ibook G4 14" 1.2GHz 768MB ram, and I have already encountered many unexpected quits and application/process hang. Examples: 1) Mac Help quits. After calling apple support, I managed to get it working again. Then next day it quits unexpectedly again. 2) So far I have encountered one unexpected quit on Safari. Always got the impression it is the best browser. I read this forum that Mac OX is very rock solid stable. Am I doing anything wrong that is causing the crash? Why is preference file so easily corrupted? Don't get me wrong, i love my new ibook. But just get a bit upset i am having so many problems so soon. I hate Windows XP but it is working better than my Mac OS now! I also wonder if some of the softwares downloaded from versiontracker or other websites may have caused some of this problems. Would really appreciate advice from mac users.
