When I press the left shift key a ± appears on the screen. It is a bit hit and miss, but for the most part it happens.
Googling I found this seems to be a common problem. The common recommendation is to reset the NVRAM and SRAM.
- I did both of those things
- It was recommended to try to reset the NVRAM several times so I did that
- uninstalled my logic mouse driver (which uninstalled the related kernel extensions)
How can I get this fixed?
[EDIT] This is a 16" MBP. I am using a matias keyboard. It is a $100 keyboard from Fry's. Pretty high end; the action is really good.
[EDIT] I plugged in an old MS keybaord I had laying around. IT was working when I traded up to the new keyboard. IT throws garbage on the screen when I press the shift keys.

Solved: For my Matias keyboard, the Mac combination for NumLock is simply the 'Clear' key. Simply pressing the 'Clear' key resolved the issue!

So ±I have this same problem with a ±Matias keyboard. ±At first ±I thought the ±Num ±Lock was pressed, as there is no numlock on the keyboard. ±Funny thing is that my keyboard is Bluetooth and was connected to Windows 10. Both the Windows and ±Mac exhibited this same behavior.±
±Pressing 'fn + N' on the keyboard stopped the behavior on Windows, but not my ±Mac ±(as you can see from this post±). The best part is that pressing Shift on my ±MacBook's built-in keyboard does not insert ±!
±Checked keyboard mappings and nothing seems to be set incorrectly. Reconnected my ±Bluetooth connection to a different key ±(keyboard has 4±), and still have the same problem. ±I'll probably let the battery drain on my keyboard and see if that resets it.
Thanks to da4 for the keyboard mapping for the normal ±.
