I woke up this morning to find my iMac whirring away like a 747 trying to take of on a mollasses runway. I opened activity monitor to see what was causing all the cpu usage, and find out that mail was at 80%! When I opened mail, I noticed it was in the midst of trying to connect to gmail's pop server. I closed mail, and the mac calmed down. Opened mail again...everything was calm. Everytime I tried to check mail on the gmail account, the cpu went WAY up, and it never goes through with the connection. I have it set up properly and it was working fine yesterday. Anyone have any ideas whats up? p.s. what's kernal task? That was at a very high cpu and memory usage as well.
