After I accidentally left my Mac on my balcony last summer and after a heavy rain when typing the mac keyboard only symbols appear.
When using external keyboard things have worked smoothly since until today when I turned on Filevault.
Now suddenly it wouldn't accept my password any longer.
Now I can only access the guest account on my mac.
And the Mac wont recognize my password even after the restore password--- nothing happens in keyboard when i try to type these passwords.
I have even tried resetting the PRAM but it would not work. Any suggestions?
