Trackpad very slow and unresponsive on C2D MBP

so it freezes completly for a short bit then resumes working again? That's strange. If it was a hardware fault, I would stay it freezes and that's the end of the story.

But if it freezes and comes back, it means that the processor choked while trying to do something and only started working back when it was done finishing such choking task.

I'm not sure how can this be tackled but maybe if you can try to force-quit when it freezes and see if that helps? Does the caps lock light come on & off when you press the caps lock during that time?

Last but not least, I've learned my lesson the hard day since my early days with a Mac. That lesson is never to continue using the pre-installed image of the OS. I usually boot from the included OS CD, format the drive and partition it if necessary or needed, and fresh install the OS. Maybe it's just my bad luck but that's what I always do.

Best of luck dude.

Try a PRAM zapping...............

i had the same problem, see if you have a box under trackpad settings titled "Ignore accidental trackpad input" checked

MacBook, MacBook Pro: Cursor reacts unexpectedly

Does the cursor on your Mac notebook move while you're typing? Do you notice that sometimes the cursor arrow doesn't appear when you use the trackpad, or you touch the edge of the trackpad and the cursor doesn't move?

MBPro 15" 2.16 120GB/2GB - Soon MBPro C2D 17" 2.33 160GB/3GB Mac OS X (10.4.8)

I have the same issue with my C2D MBP. If I read you correctly. The computer doesn't freeze, gifs keep playing, music keeps going, menumeters change, but the cursor stays stuck, but after a few seconds it comes loose. And I do have "ignore accidental trackpad input" checked as well.

And no, I'm not sweaty or oily, and during one freeze I was only touching the macbook at all with my index finger on the trackpad, nothing on the arm-rests.

I really don't want to have to send it back 😟

Before re-installing as above (which is a viable option before returning the machine) run Onyx or Cocktail on your new MBP set to clear ALL the caches and repair permissions. Onyx is available free at VersionTracker.com or MacUpdate.com.

I think I may have found a "lead". The problem went away for a while after Onyxing it, and didn't appear at all in XP as far as I could tell. However, I just had a relapse, BUT I found a pattern. I had a finder window open and had just used the keyboard to highlight a folder (ie. pressing g to highlight my games-folder). So I tried it again, press key on keyboard while circling with the trackpad, and it froze maybe five to ten times just after I pushed the keys. But didn't freeze when I didn't push any keys. But then it acted perfectly, even when I pushed keys. Then after a while I got the same "cycle" with the cursor stopping when the key is pressed.

Odd indeed, but at least this feels more software oriented to me now.

my MBP operates exactly like yours. It's as if, for the trackpad, everything else has priority. I have fooled with the prefs to no avail. Feels like software, definatly. especilly since I had the trackpad replaced and still has the same behaviour. I'm a recent Post Doc and paid for thi sour of my own meger funds so I'm upset that a $2700 machine does this.

As a troubleshooting step, you might want to launch Activity Monitor and leave its window open and viewable at all times. Then when the cursor freeze occurs you can observe which process is dominating the CPU at the time of the freeze. This might allow you to track down the root cause of your problem.

Hmmm. I'm not sure what to suggest other than some more experimentation to isolate the problem. Does the problem occur in all programs or just one? Has it ever occurred in the Finder?

Have you tried using a mouse instead? Does the problem exist when you use a mouse? If you haven't tried that, I would say hook up a mouse and use it instead of the trackpad for a few days. If the problem fails to manifest itself, you will have isolated it to some anomalous trackpad problem. If that is the case, I would contact Apple to have the computer serviced.
