I have a MBP 2.4 GHz with 2GB 667 ram using OS 10.4.11 This slab of metal is giving me trouble. Very slow operating speed. The power just doesn't seem up to par. I get really frustrated when using Aperture, iMovie, iDVD, iPhoto, dreamweaver, safari, and so on. It seems there is always a lag with windows opening and programs operating. Anyhow, I would like to take my laptop in to the apple store and have them do a check up on it. The only problem is that there is a good chance I could possibly have software on my mbp that I didn't purchase. My question is, do they look for this kind of thing and if they do come across it, what kind of action do they take if any? thanks. here is the XBench for my mbp.
