Option key doesn't work when booting
Hi. My option key stopped working when I boot and I try to use it (for instance, to choose another startup disk or to reset the PRAM). It works normally when I'm using the computer afterwords (after signing in). Also, when my login screen appears, there are a bunch of dots filling in the password field, like if the computer was filling in the password itself (but it doesn't, I have to delete the chain of dots and enter my password). But this dosen't happen when I try (without success) to use the option key on boot.
- If I try to use the option key on boot, nothing will happen but my login screen will have a normal behaviour (empty password filed)
- If I do nothing on boot, I have a self-filling password field on the login screen.
