I have apple care for 3 years. Basically my MBP is being painfully slow in opening itunes for example. What used to take 3-5 seconds now takes 10-15 seconds upon boot up. The longer the mac is on, the slower things get. Once an app is open, its fine but opening up an app have 2-3 days will take a minute. How can i resolve the problem? looks like HDD or RAM? will apple cover this? whats the proces?
