Trackpad very slow and unresponsive on C2D MBP

I seem to have varying degrees of success duplicating the bug. However, one thing that works one minute won't work the second time around. Yesterday I could get it to hang if I clicked on a menu in Safari and used the keyboard to select a menu-item. It locked up every time, for about a minute, then it acted normal. Then I tried it again later and it hung, then I couldn't get it to hang. I've zapped the PRAM now, I'll be doing an archive and install later tonight if it hangs again. If it still hangs, full erase and restore tomorrow, and after that I'm calling apple.

Oh, and Stefan, was that a C2D MBP? If so I'm going to tell Apple that and request a new machine instead of a replaced trackpad.

To me it seems like it's either software, or something weird with the logic board/input controller, like it gets confused when receiving input from both at the same time, and if so, switching the pad obviously isn't going to help.

Still remained, I managed to get it to freeze by pressing two keys on the keyboard while browsing a safari page and moving the mouse, as well as highlighting menu items in the menus again. As well as when pressing command+n to open a new Mail window.

I haven't been able to replicate it in the installer though, which I guess is a plus.

Unfortunately, I didn't get an option as to whether I wanted to archive and install or erase, or just upgrade, so I'm not sure what installation I'm doing right now 😝 So if it works, I'm still going to do an erase and install either way to get a fresh system.

Clarification: when I said mouse, I meant trackpad/cursor 😝

I made a video showcasing the bug as it exists on my system:

Once again, when I say mouse, I mean cursor 😝

Naturally it doesn't just show up in the menus (or in just safari), as that would have been an insignificant problem, but it seems this is the most reliable way to duplicate it for me. It still doesn't work every time though. And I haven't been able to do it with a mouse.

And the reinstall didn't do any good (obviously), but more importantly, I managed to duplicate it in the Mac OS X installer a few times. Which I guess would indicate that it's a hardware problem since that software runs off the DVD.

Just for the **** of it I'm going to do a proper erase and install on the whole thing, but I doubt it'll make any difference.

Could anyone with a "healthy" MBP C2D try to replicate it?

Hehe, too late, already did. Though I didn't have too much on it anyway. I'll just have to replay a few levels of HL2 and copy over some files from my G5 again, no biggie.

But I'm about to call it quits on this one, and I'll be calling Apple on Monday to get a replacement MBP. Anyone know if they have a policy on replacements vs repairs? I mean, it ought to be cheaper for them to just send a replacement and send mine to someone else than potentially have to pick mine up several times.

I didn't think it was a huge problem at first, but somehow it seems it's gotten more frequent now, and this is the only computer I'll be affording for the next five or six years, so unless it's fricking tip top I won't keep it.

Now if only I can send it away so that I'll get a return before my girlfriend gets here, she'd give me **** if my "$2000 toy" was broken from the get go 😝 I'm quite content with the crap I've gottne just for buying a Mac.

Well, mine's a 15" 2.16 stock config. I wouldn't be surprised if it's connected to the 15"'s logic board.

Good, I was going to do the same but they're close for the weekend over here. Hopefully they might have made some progress until I call them.

Mine is a CD nto a C2D.

I am experiencing this exact issue with my new C2D 15" MBP (2.16 stock). I didn't notice the problem until after I installed Microsoft Office 2004. This has been the only software addition since taking receipt of the computer. Perhaps this was just a coincidence but I was curious to find out if those experiencing the cursor freeze have Office installed?

The cursor freeze problem was most noticeable to me while using Safari and iTunes. I was also experiencing hang-ups while scrolling with the remote in the Front Row software as well.

I did notice some improvement after booting from the installation disc 1 and performing "repair disc permissions" included with the disc utility software. I have only experienced one cursor freeze today but this should not be happening at all on a brand new computer.

I hadn't installed Office on any of the three installations that I got it to freeze in, so I don't think that's the culprit. I'd agree about it happening often in safari, but I think that might just be because it's the app I spend the most time in, since it has happened in other apps as well.

And as I said before, when the error is there during the install-process, with no applications yet installed, I don't think it's to do with any specific app.
