Jumpy or Shaky Pointer on MacBook Pro

I have a macbook pro as well and was experiencing the same issue. I called apple support and they said to increase the tracking speed of the mouse through the system preferences menu. It seemed to help for now but I haven't played around long enough to see if it will come back.

I have had the same problem in the past with my mighty mouse. To fix the problem I have turned it off to lose the connection then reconnect the bluetooth. Seems to work fine then. A reboot also worked for me.
The problem is very intermittent for me... has only happened about 4 or 5 times.

Good luck.

Well, I've got 10.5.1 and I have the same problem. I've tried plugging in an external keyboard and mouse, unplugging it, unloading and reloading the trackpad kernel extension, and logging out, and the only thing that works is a reboot. It isn't every time it goes to sleep, but I haven't figured out the pattern yet. I really hate having to reboot my machine to fix it.

I have a similar problem on my MacBook Pro. My cursor gets very jumpy but only when waking the machine from sleep. I've tried adjusting the tracking speed but it didn't seem to make any difference. The only way to get back to normal is to restart.

This never happens on my girlfriend's MacBook...only my MacBook Pro.

Same here with my SR MBP, it sometimes takes a while to wake from sleep (sits there with a black screen for ages) then when it loads the mouse is jumpy / jerkey

My install is a tiger upgrade not a fresh install. anyone else?

I have the same issue running Leopard (upgrade installation). It started yesterday and since then I had the shaky mouse pointer every time I try to wake my MBP from sleep. I also experienced the black screen. Changing tracking speed (or trying to) doesn't have any effect, after a reboot everything works fine.
Hope they will fix it with 10.5.1.

Same here. Definitely an intermittent problem, but it's unrelated to either CPU load or memory usage. I woke my MBP from sleep, noticed the jumpy cursor, and went about trying to find the culprit.

Quit every application (except terminal), killed off a bunch of background daemons, restarted the Finder, restarted the Dock... nothing worked except a reboot.

Same thing here when I came back to my machine, but it never wen't to sleep totally, just the screen, and now the cursor is jumpy. This is the first time it happens for me and I've put the machine to sleep several times a day since Leopard was released.

Update:
Logged out and back in again, and cursor moves as normal again.

I have the same issue with a user's MBP. We upgraded in place from 10.4.11 to 10.5, and then updated to 10.5.1. I called Apple Support, and they instructed to Archive and Install. I'm doing that as I type, and will report my results later.

Having the same problem. Got a slightly used MBP 2.4 and immediately did a clean install of Leopard, updated to 10.5.1. I began noticing the jerky pointer within a couple of days. It usually happens after the computer has been asleep for a while. Some have thought that it might be related to Parallels but I did not install that, nor is it related to Time Machine because I haven't used that. Activating Dashboard does not seem to to cause it either. Not sure what causes it, but rebooting fixes it, temporarily.

Same issue here. Restart is the only thing that works. I have also experienced the black screen after waking my Macbook Pro from sleep (several times). I waited about 2-3 minutes each time and then forced a restart. That seems to be the only thing to bring it out of that state.

Exact same problem. I am glad I'm not the only one. Hopefully there will be a massive bug fix for Leopard soon. Anyone else annoyed that Frontrow can't integrate with AirTunes?

Same problem here. Brand new MBP with Leopard. Happens on wake from sleep.

Same issue. Did clean install. MacBook Pro C2D 17"

only occurs after waking from sleep. sometimes keyboard & mouse are complete non-responsive.

So did 'Archive and Install' solve the problem?
