Resolve Macbook Pro trackpad response issue Desktop
The Macbook Pro trackpad is very sensitive, and this falsely triggers the Accidental Input detection in Tiger. The result is that the trackpad seems to lock up for a few seconds.

The fix is easy enough: go to System Preferences > Keyboard and Mouse > Trackpad, and uncheck Ignore accidental trackpad input. I turned that feature off and I haven't had any further problems with the trackpad not responding.

Resolve Macbook Pro trackpad response issue

This hasn't worked for me at all. I've had that option checked since I bought my MBP and I still have times when the trackpad doesn't respond for a second or two (sounds like a short time but it feels like forever).

I've got the most recent software updates installed. Still hoping for a software fix from Apple...

But the suggestion is to turn it off.

So are you supposed to check it (turn it on), or turn it off. The hint seems to contradict itself.

Authored by: hollywoodpix on Dec 20, '10 05:09:58PM

I have two macbook pro 15" machines..and a 17" macbook pro-
The 15's have a similar problem in that often the trackpad is completely useless..grabs and drags and opens menu dialogue boxes when IT wants to. this seem to happen way more in the cold of early mornings..WHY?
my 17 NEVER has done this.
And just for the record the 'easy' FIX" requires a menu item I cannot find...?
I am using Snow Leopard.
any ideas??

I think there is a typo in the hint - uncheck the box and see if that helps.

Works for me. I had the "accidental input" checkbox checked as a matter of course as per my previous laptops and noticeed a slugishness in response. Now, with the box uncheked the cursor or scrolling works immediatly, but so does the "accidental input" so I guess it's a wash as to which is more annoying.

Does anybody else find it frustrating that the trackpad is not centered with the keyboard home position [Spacebar-F-J keys]? My right palm is always overhanging the corner of the trackpad on my 15" PB. Ignore input has never seemed to work for me. This has really frustrated me with Apple laptops.

I've suffered from the same problem on my 15" PB (PPC). "Ignore input" has never seemed to work. For a time there I had to just disable "tap clicks" and resorted to using only the physical button for mouse clicks. Now I'm back to just being ever-conscious of where my right palm is.

trackpad not centered is painful
Authored by: Scripter12 on Apr 26, '06 02:16:27PM

This has bugged me since the beginning. The trackpad needs to be moved or resized to avoid accidental inputs from your right palm.

I tried to just cover the trackpad with something but it didn't work. You need to cover part of the trackpad with something like a thin piece of aluminum that does not touch the trackpad itself. This is too much effort for me. I just try to be very careful about accidental input.

Reason + alternative suggestion
Authored by: PopMcGee on Apr 26, '06 03:49:24PM

The reason for that is that people often click with the right hand while holding modifiers like shift, cmd, alt with the left hand, and this way both hands don't have to travel as far.

My setup is no "ignore accidental input", and no "trackpad gestures - clicking" (i.e. always use the button to click). Works perfect for me.

Yes, this works, but now, due to the sensitivity, I end up switching windows or clicking in the wrong spot an awful lot. I'll stick with the trackpad not responding every once in a while over me writing into the wrong space when my wrist brushes it while typing, and not clicking buttons accidentally when I'm not ready to.

I'm not satisfied with this solution. Unchecking the box makes me accidently move the cursor all the time (even not really touching the trackpad is enough!), when typing or doing other stuff. I ended up checking the box again, rather have a small lag than findig my cursor in the wrong places all the time.

IMPORTANT re this issue: Apple today released Apple Keyboard Update for MacBook Pros: http://www.apple.com/downloads/macosx/apple/applekeyboardupdate10.html

I've downloaded and installed this, but havent had time to test it thoroughly, but I would guess that this fixes the trackpad lag!

I have tried the update and it seemed to fix the problem, BUT it will disable most solutions that get rid of the CPU whine on the MacBook Pro. Neither Mirror Widget nor MagicNoiseKiller still worked. You'll be stuck with using the QuietMPB application to kill the noise, which consumes about 6% of CPU cycles, reduces battery life and heats up your MBP.

So I'd rather stay away from that update if you're on an MBP.

The update was already installed, but I still had the lag problem. I unchecked the "accidental" box and it now works flawlessly.

A thing to note, from Apple's own Help: When you have "ignore accidental trackpad input" clicked, you must first touch the center of the trackpad after typing to resume your mousing. If you press the left or right edges, it thinks this is accidental input and ignores it.

I readed all posts in this topic because i had the same problem. But didnt find the solution. Than i tried removing the batery and the touchpad and mouse now works perfectly. So i think that this problem was caused from my damaged battery on my MacBook pro 17".
I hope this is usefull for you too.
