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?

  • What do you want to know? How to save your data? Obviously you should have your keyboard fixed...

What Mac are you using (Macbook Air / Pro)? Does it have a replaceable disk?

If the disk is not replaceable, I see the following options:

  • Assuming the T key is still functional: Access your Mac in target mode and unlock the disk from the other computer. For example this article explains the procedure.
  • Assuming the cmd and R keys are still functional: Recovery Mode
  • Assuming the alt key is still functional: Same as above, but you manually select the recovery partition

Sometimes the filevault2 volume cannot be opened easily. See here for a workaround.

If the disk is replaceable I would remove it asap, unlock the disk, and save the data e.g. with an USB-IDE adapter (like this one).
