MacBook Pro Trackpad And Keyboard Issues

And you know better than to press Caps Lock when entering passwords—Apple even alerts you when you have it accidentally enabled. Early key IBM keyboards had a numeric keypad that doubled as arrow and other keys for text-screen-based interactions. The Num Lock key was a product of the intermediate age, where mechanical and digital met.

1. Clean the keyboard

IBM doubled up: It added a Num Lock key that flipped the numeric keypad to act as arrow keys to move a cursor around a screen-based interface, before computer mouses. On certain laptops, including older Macs, Num Lock had a different function.

What to do if your MacBook keyboard is not working

Lacking a numeric keypad, Num Lock turned part of the main keyboard into a pseudo-keypad. There was sometimes a unique Num Lock key, sometimes it doubled with a Clear key and Shift, and sometimes it was a function to invoke, like through F6 on a Mac.

I then suspected my Mac internal hard drive was malfunctioning, so I went ahead and pulled out Disk Utility and several other apps to check Mac hard drive health. It turned out the main drive is working fine without any problems. Check out this and this article from Apple. And guess what? Nope, the Mac cursor still kept jumping and clicking and moving on its own after that. Check it. Now the erratic cursor jumping issue should disappear. And you should be able to use your external mouse to navigate smoothly on your Mac.

Note: we recommend this tip to Mac power users only. Anyway, I hope the simple guide has helped you resolve the erratic trackpad issue. I tried the solution on my MacBook Pro, and it worked. Feel free to leave a comment below and let me know how it works for you? I have a Macbook pro where the cursor position jumps randomly.

I tried an external trackpad where I check to ignore the built in trackpad - same problem. I purchased an external mouse. The Senior Advisor was just a bully and hung up on me. I figured out the solution below for one application, but it might provide a more universal solution—disable the keyboard navigation key-combinations.

I think this is a general hardware issue.. However, specifically to my word processor: Nisus Writer Pro I discovered that 1. The cursor was jumping backward in the text to the last insertion point. There is a key-combination for this: Command [ , and to go forward to the next insertion point Command ], 3. I can duplicate the issue if I touch the TrackPad, then hit either [ or ] the cursor will jump back to the last insertion point.

Things I Tried But Didn’t Work

The NisusWriter commands are very specific, the trackpad sequence is either bracket. I suspect that it might be happening anywhere there are similar key-combination shortcuts. I hope this helps. Hope this helps some people. The Apple woman was really snarky and not helpful. I expressed frustration, she was just looking for an excuse to hang up on me.

My God thank you. I was 5 seconds away from hurling my laptop out the window.

How to Troubleshoot the Trackpad on a MacBook

You saved me a couple of grand there. I often kept my iPhone right near my Macbook Air. Read somewhere that sometimes Bluetooth devices can interfere with each other. Turned off the Bluetooth on my iPhone as a trial, and the jumpy, erratic cursor immediately stopped.

1. Check the mouse’s batteries

I was able to use my external mouse based on the article, so thanks. I use Alfred, but the process is generally the same: trigger the utility with its keyboard shortcut usually Command-Space or Control-Space , type the first few letters of its name, and then hit Return when the correct app appears.

You can also use those tools to run quick calculations. If you really want to keep your fingers on the keyboard at all times, you can actually use your number pad to move the mouse cursor. Then you can move your mouse—and even click—using the right keys.
