hello!! i am running osX tiger on a dual g5, and when i got the computer it was super fast. nothing ever crashed, it would start up from off to ready to go in ten seconds. i was in love. now it takes a very long time to start up. safari crashes all the time. photoshop runs super slow. im sure i have done something stupid to mess it up, but i cant figure how to cleanse my comp!!!! before i made the switch i would run adaware, i would go to start-run-msconfig and get rid of startup items that i dont know or dont need. now that i am on a mac, i dont know these little tricks. can anyone give me some advise? thanks a whole bunch!!!!
