Certain keys on my keyboard aren't working and because of this I can't enter my password and login to my macbook. I tried to disable my filevault in recovery OS but it says "the supplied password failed to unlock the disk" , but I know it's the correct password. I also tried to password as it suggests but once I get back into the login screen it won't allow me to login.
Any help would be greatly appreciated!
MacBook Air
Hi,
Connect external keyboard to MacBook Air if it works correctly.
If it works, you'd better make Genius Bar reservation to take your MacBook Air to Apple authorized service provider to check the keyboard.
I had that problem my self.
I got a cheap USB cable keyboard and restarted my MBA.
It worked with that keyboard.
I would try by Resetting the NVRAM that holds your keyboard setttings
Resetting NVRAM
After resetting NVRAM, you may need to reconfigure settings for speaker
volume, screen resolution, startup disk selection, and time zone
information.
Can you try to Start up in Safe Mode ?
hold shift key during boot
Well then there is a serious problem.
Try the Internet Recovery with hold down the Command (⌘) – Option (⌥) – R during booth.
If that does not work, hope you have USB with OSX on it.
Open keyboard Viewer
Click on the Flag in menubar
Now type keys on your keyboard and watch them in keyboard viewer
You can also use the keyboard viewer to type by clicking on the letters in it
Yes I've tried the external keyboard. It works when I attempt to change the keyboard in recovery OS, but once I've changed the password and return to the login screen the external keyboard no longer works.
Well most of the top row of letters (q-p) and bottom row of letters (z-m), but it differs everytime I turn off or restart my macbook. Sometimes maybe only 1 key works. Also the keys aren't functioning properly. For example when I press the letter "m", quotations (") is what shows up.
Yea I have one too. I just tried resetting the NVRAM like you said but this time I did it with my usb keyboard. The macbook keyboard still isn't working and it doesn't allow me to type in my password with the usb keyboard. But my computer did restart when I reset it.
Certain keys on my keyboard aren't working
Which ones exactly??
Thanks but it's not working. All the keys aren't functioning properly either. When I press a certain key i.e. "m" it outputs the quotation symbol (").
I can't access this because I can't login without my password and the nonfunctioning keys won't allow me to enter my password.
How do I do that?
It won't start up in safe mode.
