Need help. Have MacBook Pro for last 5 years. It has OS X 10.5.8, 2 GB RAM and 4 GB of free cpace on 80 GB HD. Recently it became very slow. I mean REALLY slow. Except for the web page that I can scroll up and down for everything else i see spininning color wheel a lot, actually all the time. I go to save something and scrolling through file list makes sliding stop and I see color wheel. If I open Word to type something or e-mail, letters I typed appear later after s1-3 seconds and so on. I try to keep just a one or two programs opened.
I tried to use Activity Monitor (utilities) and looked at CPU load and memory load and see nothing dramatic there. Low load on CPU and 300-400 MB of free RAM. Disk activity monitor displays peaks even that I am not saving anything at the moment. I really don't know what to look at to recognize a bottleneck in the system.
I must say that my oldest 20" iMac (about 6 years old) slowed dramatically with about same simptoms. My newest 24" iMac is still the fastest of the bunch but it is kind of going in same direction by slowing down. This is typical Windows behaviour and when I started purchasing Macs they promised me that it will never happen.
