Karabiner-Elements: Karabiner-Elements does not work on macOS Big Sur 11.3 beta 1

Karabiner-Elements does not work on macOS Big Sur 11.3 Beta 1 due to a macOS issue around DriverKit. Please wait until Apple fixes the issue.

Detail

macOS Big Sur 11.3 beta 1 has an issue that loading the third vendor DriverKit driver will be failed.

Karabiner-Elements does not work until Apple fixes the macOS issue. We have to send a report to Apple by Apple Feedback Assistant about macOS refuses the third vendor DriverKit driver in order to fix the issue.

The macOS’s kernelmanagerd error message:

2021-02-07 10:41:17.913667+0900 0x379      Error       0x0                  104    0    kernelmanagerd: 
Error occurred while handling request "DextLaunch(arguments: Optional(["Driver Extension Server Name":

"Check In Token": 18947, "CFBundleIdentifier": org.pqrs.Karabiner-DriverKit-VirtualHIDDevice]))": 
Invalid argument: Can only launch dexts from a verified SIP protected path

You can confirm the error message by the following command on Terminal.

log show --predicate 'sender == "sysextd" or sender == "kernelmanagerd"' --info --debug --last 1h

I’ve filed the issue as a DriverKit issue. (FB8994577)

As I only use Karabiner Elements for swapping the right command to left control (I’m a vim user and using the left control hurts my hand after some time), and I don’t want to upgrade to a beta Big Sur, I’ve used the built in hidutil tool from apple:

0x7000000e7: Keyboard Right GUI == Keyboard Right Command
0x7000000e0: Keyboard Left Control

hidutil property --set '{"UserKeyMapping": [{"HIDKeyboardModifierMappingSrc":0x7000000e7, "HIDKeyboardModifierMappingDst":0x7000000e0}] }'

Great news everyone! This seems to be fixed in today’s B2 release.

It would be awesome if they stopped breaking the same thing repeatedly… cmon, Apple!

@neilio What is 20E5196f you mentioned? Is this karabiner-elements’s version?

macOS 11.3 build number

Before updating to 11.3 Beta 3, I just want to make sure that there the issue hasn’t been re-introduced

I’m on 20E5196f and everything is working as expected.

I just updated to Big Sur 11.3 and Karabiner-Elements stopped working for me as well. It won’t load the driver. I’ve done the recommended uninstall / restart OS / install and it still does not work. Tried with Karabiner 13.3.0 and the 13.3.1 beta.

Log shows: [warning] [virtual_hid_device_service] driver_version_ is mismatched: client expected: 10300, actual dext: std::nullopt
