Hi, My mac keyboard and mouse have stopped working. With the mouse it will now only left click, even when pressing right click. And the keyboard letters are all mixed up (if I press "f" it will show a "t" or act as if I've pressed "enter" or something). I have tried with 2 mice and the problem persists (only have one keyboard). So I assume it's the software. Has anyone else had this problem? The annoying thing is I can't even restore to factory settings as the computer doesn't recognise me pressing command and r during the startup. Have no idea what to do! Any help really really appreciated. Thanks
