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.
