My keyboard number pad has been messed up ever since I installed OS X 10.10.4.
The numbers type as follows:
when I press "1" increase volume key goes up as well.
When I press "2" the ' key comes up as well.
"3" some wired key.
"4" ] comes up.
"5" [ comes up.
And "6" the equals sign comes up.
And vice versa for the concurrent keys. 7 and 8 as well as their shift keys work fine, 9 highlights everything in shift and goes to the beginning.
I've tried a reinstall and a separate Bluetooth apple wireless keyboard I have seems to work fine.
Please help I've scoured the Internet for answers, nothing has worked.
