Track pad cursor on MBP erratic!

I can barely get the cursor to stop jumping around enough to write this. It's like something is stuck. It will not follow my finger(s). I tried to adjust Preferences, but nothing I do affects the way it behaves. Help! Thanks for any input. Kate
PS it also won't scroll easily. I'm having a hard time getting to the bottom of this page so I can submit my question.

I asked the hosts to relocate your question to the MacBook Pro Forum.

You may have to send it again for repair.
It is not that common that trackpad is failing second time around.

I have problem with my track pad cursor ..need help pls?

my mac book pro track pad is not working as it should.. it goes different direction . what shoul i do ?? any way i ca reset the track pad . i tried with track function didnt work ?

wangyal3y4,
open the Trackpad pane of System Preferences, and select its Scroll & Zoom tab. If its “Scroll direction: natural” checkbox is checked, uncheck it; if it’s unchecked, check it.

Imac 2009, 10.7.4, track pad cursor locks up and won't function

My cursor has locked up the past few days.
It won't function at all except to move around. I've had to do a hard shutdown and restart to get things working again. Any suggestions?

Select  ▹ System Preferences ▹ Bluetooth. Select the device in the list on the left, then from the action menu (gear icon) below the list, select Update Services. If there's no improvement, delete the pairing from the list and recreate it.

Track pad cursor jumping around without being touched

My daughter has a macbook pro 1.5 years old running OS 10.6.8 and for the last two weeks has had the cursor jumping around and clicking on anything and everything. She is in college and uses airport to connect to college network. What is the problem?

You have some type of hardware problem. More then likely the battery is swelling and putting presure on the trackpad. The only thing to do is take to Apple and have them check it all out, replacing any parts that are needed.

OS X 4.6 - Erratic Track Pad

Just installed OS 10.4.6 on my four macs. I had no problems except my 15" Alum. PowerBook G4 (1.5 ghz, 1 gb Ram) where my track pad has become very erratic to the point of not being useful. The cursor movement is very erratic. Yet the cursor moves smoothly when I use a USB mouse.
Rebuilt permissions several times including using the original OS 10.4.3 disc. All to no avail.
By the way, the update went without a problem on my iBook (1.33 ghz, 1 gb Ram).
Any suggestions?

I have read that after updating, you should only repair permissions from the desktop disk utility, not the original install disk.
Try disk utility>Repair Disk from the install disk.

Erratic cursor and track pad when using 220v on MBA

Hello
I am travelling in Europe with my MBA, and I have noticed that when it is plugged into a 220v outlet the whole case has a slight electric charge (and a very slight vibration), this apparently makes the track pad very erratic, with the cursor jumping all over when I try to move it. I have resorted to unplugging the MBA when I want to use.
Any thoughts/solutions on this?
Thank you,
Peter

3 prong grounded extension cord may help.

Cursor and the track pad are acting erratically.

I have a 13" MacBook Pro (mid 2012). Currently have Mac OS X Lion 10.7.5 (11G63) install. My cursor and the track pad are acting erratically. Any suggestions. Google wasn't a great help.

Replace your MacBook's battery ASAP.

Track pad responsive at first then erratic

18 month old 16 inch macbook pro. Track pad responsive when computer first turned on then after a few minutes track pad erratic and unresponsive. Cursor floats, stubborn movement. When external mouse plugged in, all works fine. How much does it cost to replace track pad? Any first aid tips?

It could also be a swollen battery, that is pushing at the trackpad. By the way, Apple has no 16" MBP.

MBP keyboard and track pad not working

Today the keyboard and track pad on our mac book pro laptop just stopped working. The mouse connected to it by usb continued to work but we can't type or anything. We tried the ^F6 keyboard shortcut but it did nothing since of course the keyboard isnt working. And it is also not the number lock key. The computer was working fine all day up until now. It is just under a year old. Any ideas?

I'm having the same problem. It appeared yesterday and then magically "repaired" itself. My MBP was fine today. Tonight the problem is back. No response from the keyboard and track pad. Track pad works fine using a USB mouse. My problem appears at start up. The cursor is in the usual upper left hand corner. It can't be moved. Restart, sleep then restart do not solve the problem.
Suggestions?

My old MBP (2005) often crashes, freezes or shows grey screen at start up. Also track pad often does not work. I have re fomatted the HD and reinstalled system but to no avail. Genius bar says possible faulty HD, but suspect logic board, any ides any body

My old 17" MBP (2005) often crashes, freezes or shows grey screen at start up. Also track pad often does not work. I have re fomatted the HD and reinstalled system but to no avail. Genius bar says possible faulty HD, but I suspect logic board. All checks out OK on the Apple Diagnostic bench. Can a Logic board go intermittant?? Any Ideas any body??

Ive repaired 1000s of laptops over the years (translate: diagnose and replace parts).
Its not that old, Ive owned 100s of laptops (most were free) ....some I still have are nearly 13 years old and still perfect, ....some extremely expensive ones died in under a year.
other than becoming obsolete at some point, there isnt really any "will spoil on" data like Milk for solid state computer parts, ....alas.
You can have a $5000 laptop die in 4 months, and a junker one keep kicking after 10 years.... Ive seen that firsthand countless times.
Common logic dictates that "very expensive = long life" in computers,..... but all the repair people will tell you just the opposite.
I know you have a gripe, I get that all too well honestly .

NO Cursor scroll through any message thread using the track pad in the BB Classic

It very strange to know that I didn't find the cursor while i will scroll through any message thread i.e. Text msgs and in Whatsapp it will only selet the whole msg or multiple msgs rather then specfic text required, using the track pad in my BB Classic.
Where in my old BB 9780 there was a cursor which would always show there and would help in selecting text required.... Rather in BB Classic first you have to activate the selection mode in text msgs by pressing the shift key an slighty brush the finger against the trakpad. then you get the selection blue sticks on the screen to selet the text required.
Anyone who has noticed this short coming...?? Or it might be I am not very familair with the selection methods...!!!
Will appreciate your help
Thanks,
Falak Zaib

This is normal behaviour. Please go to the "Tutorial" app select
"Editing Text"
It will show you exactly how it works.

HT203171 Track pad is erratic, sometimes scrolling without touching the pad. Also highlighting chunks of my Thesis with the touch of a finger. Frustrating because I have accidentally deleted during this out of control mechanism with the track pad.

My Mac Book Air has developed an erratic process with the track pad. Sometimes the page scrolls without touching the pad, great chunks of my Thesis can be highlighted and sometimes I delete without realising. Does anyone else have this problem. The Tech wants to replace my track pad today, not sure what to do?

Erratic track pad pointer.

Hi new to the community. First post. I have a 2012 Macbook Pro (15 inch). I am running OS X Yosemite. For no reason at all, all of a sudden the track pad arrow is erratic and highlights words and gives the dictionary definition, moves the pages around and is driving me nuts! I am not a computer geek. I just want it to work. Any suggestions?

Hi. you can read this link for some possible solutions. https://support.apple.com/en-us/HT203171 You could also try a pram reset. Command/Option/P/R keys at startup for three chimes.
