Key mapping no longer works after 13.0.0 update

I tried to re-install the program
I tried to re-define my mapping
I restarted the program and the system
I tried to map various keys: letters, function keys, modifier keys - the issue applies to all keys
karabiner_grabber and karabiner_obsever are enabled in system security settings.

Here's the log:

Thank you for feedback!

Seeing the same behavior.

MacOS Catalina version 10.15.2 (19C57).

My MacOS version: 10.15.7 (19H2)

I encountered the same issue after upgrade to version 13. All the mapping does not work.

The driver alert is always come back after all methods: safe-mode, disable other apps on mouse event before clicking allow...

Here is the log in the Preferences:

Same issue here for macOS 10.15.2 and karabiner 13.0. Revert to 12.10.0 and everything works again.

Could you show me /var/log/karabiner/virtual_hid_device_service.log? You can confirm it in Console.app > Log Reports > virtual_hid_device_service.log.

Sure, but I don't know how helpful it will be because I already downgraded to 12.x and updated again to 13.0.0. Now everything works fine.

I can still see the grabber_client error: Connection reset by peer error, but mapping works fine now.

I confirmed macOS Catalina sometimes fails the activate the driver property. In this case, restart macOS just after deactivating driver may solve the issue.

https://karabiner-elements.pqrs.org/docs/help/troubleshooting/driver-alert-keeps-showing-up/ (macOS Catalina Note #1)

hi all +1, macOS 10.15.7, karabiner 13.0.0 key bindings (actually one key binding caps_lock -> f19) stops working after i launch vmware fusion guest vm o_O also karabiner device disappears from System Preferences - Keyboard - Keyboard - Modifier Keys...

thanx.

@deadElk Thank you for feedback! I tried running Debian 10 on VMware Fusion on my machine, but could not reproduce your issue, unfortunately.

Is there any crash report? You can confirm them on Console.app > Crash Reports.

I had similar issues with v13.0. When I opened Karabiner Elements, I getting the popup saying the virtual keyboard was not installed. I went through the steps to deactivate the keyboard, but when I clicked "activate" keyboard, nothing happened and was not prompted in the system prefs menu to install it, so my keymaps didn't work. Reverted to v 12.10 and had no issues. Running MacOS 10.15.3.

this is the last one out of 10+

@deadElk Thank you for the crash report! This crash causes your issue. Please use Karabiner-Elements 12.10.0 until it is fixed.

I have not yet been able to reproduce this crash, but I'm working to fix it.

@theothermattm Judging from a lot of feedback, Karabiner-Elements v13.0.0 requires macOS 10.15.6 or higher because macOS 10.15.5 or earlier has an issue around DriverKit. Please downgrade to v12.10.0 while you are using macOS 10.15.5 or earlier. https://karabiner-elements.pqrs.org/docs/releasenotes/

I have not yet been able to reproduce this crash, but I'm working to fix it. just tested:

create guest VM

select CD with some linux ISO (have used zorin os)

boot from CD

let's the system boot automatically to the installer

check the Modifier Keys - Karabiner driver disappeared

P.S.: guest VMs tested are pinguin, freebsd, macos i think vmware has it's own HID drivers and there is some conflict with new native karabiner's driver

is there any way to restart HID subsystem without rebooting? very annoying procedure ...

I have macOS 10.15.7 but v13 also doesn't work for me. Downgraded to v12 that perfectly works. Will wait for macOS 11

same issue on macOS 10.15.7

It stopped working suddenly yesterday. I reinstalled 13 and it started working again.

@deadElk I fixed this issue at the latest beta version (v13.0.12). Please confirm it.

It seems to be working fine. Thanks for the fix!
