hey all. ive been using my mac for around 7 months now and its been more or less fine until now. just the other day, i was starting up a few programs and i noticed that the loading time for each app had grown to be about 10-20 seconds each. ive been running the same few apps, but since it's gotten so slow, i'm even afraid to open up my dashboard.. even the typing freezes every few seconds for around half a second, no matter what application im typing into. has anyone else been experiencing this problem and how did you guys deal with it? thanks a lot.
