Hi,
I have an A1398 MBP, which was working fine until last couple of days. I will list the series of events that occurred:-
1. It suddenly started booting in safe mode.
2. Did not accept the password.
3. There was a left shift key issue seems to be.
4. Used the Right shift to key in the password, successful, but the mac was slow.
4. An update for the OS was pending.
5. Installed the update.
6. After the update, it did not accept the password, tried to reset the password, but it is not accepting the updated password.
7. I tried to do a recovery using Command+Option+R keys, it went to Internet Recovery, downloaded files, but thereafter displayed the white prohibition screen.
8. So, I am unable to login, unable to reach the disk utility (even with Command+R, it goes to login screen)

Kindly support if you have faced this.
Thanks in Advance.

Do you have a firmware password set up?

Or just a regular account password?

If you suspect a keyboard problem, do you have an EXTERNAL USB keyboard you could plug in and try?

Hi,
I had tried the above mentioned steps using a wireless keyboard, after i realised the shift key stopped working.

Thanks
