My macbook is relatively new and, for some reason, the numbers and letters won't type. It seems like I've looked up every shortcut and I haven't found one that works. I found a post somewhere else like this but there wasn't an answer. The track pad and mouse work perfectly, and when I startup my keys will type in my password, but after logging in they stop typing. The F keys and the command and control and option keys also work along with delete and the arrows but enter and neither shifts work. I'm not sure if this is in the correct spot so if it isn't I apologize.
