MAC OS 26 Tahoe update prevents login with correct password u

Like I said I updated my MacBook last night to Tahoe. Everything looked good and it restarted like normal. I went to log in and it said my password was wrong. I have been using the same login password for years.


I have also tried to reset my apple password and was unable to do so .


What do I do?

After install of Tahoe 26.1 the login screen wouldn’t recognize my password. Multiple restarts, reinstalling Tahoe, resetting my password through Recovery mode → Terminal resulted in ability to login to Recovery, but not the main screen. Thanks to the comment above, and a long conversation with great support at AppleCare, I finally noticed the tiny TUR in the top right corner of the screen. The system had for some reason changed the keyboard layout to Turkish, so of course the password didn’t work. When I changed it back to Canadian, everything was fine. Basically 2 hours wasted, but now we are back on track.

I had similar issue.


For last 5 years I've been using macbooks 2019 and never had any issue with entering my password, I have always used Turkish Q keyboard and same password for years. After installing Tahoe 26.1 today, my password did not accepted.


I tried multiple times - the system locked me out for 15 minutes. After that (luckily), I thought about maybe the keyboard settings turned into US- UK settings for some reason - and since my password has Turkish letter ''i'' in it, I remembered for turkish keyboard it would be dotless ı - and it worked!

I managed to log in only because I had prior experience with an English keyboard layout and guessed the key mapping difference. Many users may not be able to resolve this. Literally, I entered wrong password purposely and solved the issue - even though the top corner keyboard shows Turkish Q - the system thinks it is not because it is accepting ''ı'' instead of turkish placements of ''i''


I tried again, and unfortunately the problem is still exists, after the update the system still thinks I am using english keyboard. I reported this to Apple, they need to ensure that the login screen preserves and applies the user’s stored keyboard layout settings instead of defaulting to English.
