keyboard typing wrong characters
I have a mid 2011 iMac 21.5", Mac OS X10.10.5, 2.8Ghz Intel Core i7
My wireless keyboard is not typing the characters that I press. The "a" and "q" keys work, but the delete key is a "q". It seem really random and obviously I can't log into my computer to troubleshoot this. I've changed the batteries in the keyboard and mouse as some others suggested. There was no water damage. I also sprayed the keyboard with compressed air and there wasn't any debris.
I followed the instructions on here twice and got he same results, which were different than what this user experienced: https://origin-discussions-us.apple.com/thread/3065163?tstart=0
Turn off your computer. Unplug for 30 sec, and everything attached. Then power it back on and hurry and hold Command + Option + P + R. I held Command + Option + P with one hand and then after I hit power I added the R.
The computer will make one chime. Keep holding it. I will then shut down and make one more chime and you can let go.
My results:
A black screen appeared with a lot of script. I never heard a chime. Some of the lines said "XXXX" is inefficient and should be removed.
And then the OSX Utilities screen appeared with the options to restore a backup, reinstall OS X, Get help online and Disk utility. I'm trying to avoid any reinstalls or restoring a backup.
Anyone have another workaround for this type of issue?
