I would like to know how to permanently disable the Alt key. I have a problem where by the computer is acting like the Alt is pressed down. Every time I type I get strange characters.
I have tried going into the keyboard preferences and disabling the Option key but that don't seem to be working. I disabled the Alt in the past this way and it worked. When I open the keyboard viewer it's showing the Alt as being pressed down.
This is a 2011 Macbook Air. I can't afford a repair at the moment.
