I am using a MacBook Pro 16 2019 (MacOS 13.2) and a very funny problem.

I created a new admin password that contains the symbols ¨^, but in the login screen I can’t introduce those symbols, because when I press the corresponding key no symbols appears. Because of this, I am unable to log into the device.

The symbols on my keyboard from Spain are done with the keys right to ñ and p (see the attached image) while holding down Shift, but I suppose that in different countries the combination may differ.

I can't restore the admin password with my Apple ID because I have a firmware password to turn on the Mac, and I don’t remember that password. Without that password I cannot restore the admin password.

What would be the best way to solve this?

More information about the symbols

Symbol ¨ [diaeresis]
ASCII code 249
HTML entity &uml
Unicode U+00A8

Symbol ^ [circumflex]
ASCII code 94
HTML entity ^
Unicode U+005E

  • Do you have an input format button in the toolbar on the screen you're seeing?

  • Get a Spanish USB keyboard so you can enter the symbols.

  • I tried with an english keyboard and the shortcuts “shift+opt+ u”, “shift+opt+ i” to add the symbols I mentioned. Thanks for your help! Unfortunately it didn’t work, the password is still not valid. I don’t know what to do right now,

  • Are you able to open "Accessibility menu" using ⌘⌥F5 ? There you'll be able to open software keyboard and enter those characters. Feb 17, 2023 at 13:36
  • You'd confused your dead-key commands. See answer below as to how to enter them.

If you enabled SSH in the past (by default disabled), you could SSH into this Macbook and use the passwd command to reset your password from there.

On a British English keyboard set to British or a US keyboard set to US English:

Diaeresis is generated by Opt ⌥ u then [space]
Circumflex is generated by Opt ⌥ i then [space]
This will not type a space afterwards, it's like adding an accent to a letter using a dead-key combo, but without adding a letter, so it adds only the accent with no letter under it.

On an English keyboard set to Spanish ISO (not Spanish, which can't do both symbols directly, as a far as I can see.) [From comments, this may have changed in Ventura, but I can't test.]

Diaeresis is generated by Shift ⇧ '
[marked single quote on UK English keyboard, 2 keys right of L]
Circumflex is generated by Shift ⇧ [
[marked left square bracket on UK English keyboard, 1 key right of P]
Same physical locations as on a Spanish keyboard.

By the way, Macs don't use Windows-style ASCII codes at all.

    Spanish ISO became “Spanish” in Ventura I think. Feb 18, 2023 at 18:14
  • @TomGewecke - ah, OK, thanks. Haven't used Ventura yet.

You may reset your password with: three times wrong password, then "Reset Password using your Apple ID". There is also a possibility in Recovery Mode (restart with Command+R or with M1-Chip hold the power button until you see "options")
