I've just started having a similar problem. It happens only after the MacBook has been running awhile; the fans start up (I'm seeing about 95 CPU temp), every application slows down. Memory shows very little free, but ~1.25 GB (out of 4) in the inactive category, presumably still available.
Looking at Activity Monitor, none of the apps appear to be hogging CPU time; closing them down one by one doesn't have any effect. Shutting down and restarting does.
I will try more of the fixes suggested here; posting now in case this problem turns out to be more widespread at the moment.
Using the DVD is a terrible way to see how the system is running as it seeks all the time and any action must first be read by at the most a 16x read speed. Usually an 8x. You'll see the beachball MORE often.
True enough. But usually you can hear the optical drive seeking and know whether the stall is related to the drive seek or not. If you get bad stalls and the drive is silent, I figure there is a problem.
Rebuilding the directory can usually suss out sectors and malfunctions or at least fail with some indicators. OP should try repairing the disk with Disk Utility while booted from the Mac OS X DVD. If it fails it is usually enough for a drive replacement from Apple.
HI I am not sure where to post this. I've run into the same issue. Slow macbook pro. I ran the install disk and the disk utility. Reported back with disk error - telling me I should reinstall my os. I have an external drive with enough space to accomodate a back up. I went through the process of reinstalling - backing up user data on the external drive. When I choose the drive I want to back up everything on to and hit ok it tells me there isn't enough space on the drive. I am perplexed - there is ample space on this xternal drive. After doing this I checked my xternal again and tried copying the data over manually - the xternal was then locked - so I found a stream of code ran it on the xternal and was able to unlock the disk. I tried to install the os again - attempting to back up the user data from the mac - again it tells me there isn't enough space on the xternal. I tried partitioning the xternal drive and again the drive locked up - I unlocked it again and tried to install the os again and ran into the same problems. Does the xternal drive need to be entirely clear of data to back up user data from the mac? The drive is functional I use it regularly. Another problem I am having is every once and while the screen goes blue - flickering from blue screen to the desktop on and off intermittently.
I bought the thing privately so I don't have a warranty and I don't really have the money to sink into this thing.
It's barley a year old now from assembly line -
For the amount of money I paid for this thing I really shouldn't be having any issues like this. I have another mac from 8 years ago that still runs just fine - never had any issues with it.
I had the white macbook before this macbook pro and the HD died on it after about a year. I think its getting near the time where I drop my dedication to mac and go with a windows machine.
