MacBook Pro keyboard typing funky characters

Post by ThankYouJack »

i have a 6 year old MacBook pro and the keyboard occasionally acts up. i tried troubleshooting before and finally reinstalled Mac OS which seemed to fix the problem for a bit.

The space bar used to type an odd character and currently the bottom left shift button + letters types characters like

ˆÅÍÎÏÒÚÔÒÔÎÏ´Ø∏‰¨ˇÁ¨ˆŒ¿Â˘Â◊ÇÍÏÍŒ„´‰ˇÁ¨ˆØ∏∏∏∏ÅÍÎÏ˝ÓÔÒÚ¸˛Ç◊ı˜Â¯


It doesn't matter which app I'm using and one minute it works fine, and then types the odd characters again. Pretty sure an external keyboard works fine all the time, but I can double check if needed.

Should I run a virus scan and if so, which one?

If anyone has any ideas, I'll give it a shot


UPDATE: It froze on me so I went to reboot it. It then kept freezing while booting, but finally went through after PRAM reset. But then the screen went black and I'm having trouble getting the screen to go back on. I remember this happening before and I finally gave in to reinstall the OS but it seems like a hardware (motherboard?) problem. It's lived a good life, but I think it's on it's last legs and I have a newer MBP that I have as a replacement.

The Googles seems to think that maybe your Option and/or Shift keys are stuck:

Maybe try typing qwertyuiop and see if your output is the same as in the link I posted.

And now it's working perfectly, although I noticed that the left option key isn't working at all. The right one works as expected.

The strange thing is if the left option key was stuck before, having caps lock on or the right shift key on should have also produced the funky characters.
Maybe pushing the left shift key, somehow was also engaging the left option key.

Hmmm, and maybe the startup problems I occasionally have are unrelated...

Maybe the keyboard is damaged? It seems you could have 2015 MacBook with the maligned butterfly switch keyboard.

Apple should repair the keyboard for free even if it’s no longer under warranty.

This would be the first thing I'd do, to figure out whether a software or hardware problem.

I missed this part on Apple’s website:
The program covers eligible MacBook, MacBook Air, and MacBook Pro models for 4 years after the first retail sale of the unit.
You could try taking your MacBook to Apple to see if they will repair it for free even if it’s past four years since your purchase.

There is a class action lawsuit for this issue.

It's the 2016 models that introduced the butterfly keyboard. OP's is older than that, it seems.

Nothing is permanent - keyboards can and do go bad. I think replacing the keyboard would be a top case replacement (keyboard, battery, trackpad, case) which is about $200.
