Well, I've had my Macbook Pro for about a year now (it's a Rev A one; 2.16 Core Duo, 2gb RAM, etc...). I am still new to Macs so please excuse me if I say anything wrong. So here's the problem, my Mac is slow as a snail now. Namely apps like Firefox, iTunes, Quicksilver are slow to launch. Startup time has been slowly increasing since the day I purchased the computer. Sometimes I get just plain computer lockups. It's kind of annoying because my old old Windows desktop ran a lot more reliably and smoother than my Mac is now . I'm guessing this isn't normal... Now, I've done a couple searches and it seems that a few people have been having the same problems as me. I've looked and tried out a few solutions like running Onyx to little to no avail. Please help me get my Mac back up to speed!
