My MBP has been feeling a little sluggish. It is relatively new, maybe 8-10 months old. I stll have Tiger, but will be upgrading to Leopard soon. It feels like it has been slower than normal to open up programs lately. I have also been having some problems with my web browsers. (Firefox will sometimes just stop loading webpages graphics and will just show text.) I'm not sure if these are connected at all. If I was still using a PC this is where I would erease any junk programs and like defrag the hard drive and stuff. Being as how I am a relative mac newbie I don't know what, if any, action I can take to keep it running like new. I checked the programs in the "Utilities" folder in applications, but didn't see anything that really seemed helpful. Like I said, I am going to be installing Leopard (and I will be boot camping vista soon afterwards) and would much prefer to begin with a system that i running ship shape.
