hidutil stopped working on macOS 14.2 update

Originator:Yaroslav.Yashin
Number:rdar://FB13465290 Date Originated:13.12.2023
Status:Open Resolved:
Product:macOS Product Version:14.2
Classification:Keyboard Reproducible:It happens every time
 
I've got the following command to run on every macOS start:

hidutil property --set '{"UserKeyMapping": [{"HIDKeyboardModifierMappingSrc": 0x700000064, "HIDKeyboardModifierMappingDst": 0x700000035}]}'

It always rebinds a key (non_us_backslash to grave_accent_and_tilde) on my international Apple Magic Keyboard to a convenient one to match with my us keyboard laptop.

Right after 14.2 install this command stopped working. It throws no error, the hidutil property --get UserKeyMapping prints out some kind a valid output as follow, but the key behaviour isn't updates after the command run as it appears before update. Also I'm not sure that in the past the --get argument output was printed out as a Decimal rather than hex. But this is as it is now.

The command output:

(
    {
        HIDKeyboardModifierMappingDst = 30064771125;
        HIDKeyboardModifierMappingSrc = 30064771172;
    }
)

Updated to 14.3, the problem no longer persists as long as you have hidutil run as root (e.g. sudo) as per:

• run hidutil w/ sudo

ps also make sure you are using the correct ProductID / VendorID...i noticed mine had changed w/ the update.

I've objected:

I can't confirm the full fix of this issue.

The issue is still persists, but with lower severity, as now the bug can be worked around with a few additional seteps.

But here's the steps to reproduce the issue on 14.2.1 (23C71):

  1. Power on and log it into a mac
  2. Input into the terminal app the command provided bellow
  3. Press the "non_us_backslash" key on an international keyboard

Actual result:

The original char will be appeared on a given input field instead of "tilde" char.

Expected result:

The "tilde" char appears on a remapped key press.

Additional info:

The expected behaviour occurs after keyboard replugging the keyboard, whether by restarting bluetooth service or reconnecting a wire keyboard. Having to do this is redundant and indicative of a bug.

The command that I run: hidutil property --set '{"UserKeyMapping": [{"HIDKeyboardModifierMappingSrc": 0x700000064, "HIDKeyboardModifierMappingDst": 0x700000035}]}'

Apple responded:

According to this[1] comment on my question on apple.stackexchange.com the same issue represents on macOS 13.6.3 as well.
