Karabiner-elements: allowing "system software from developer" not working

[hovzik]

got a clean (new) macbook and trying to install karabiner.
macos 10.14
karabiner 12.2.0

1. when run first time, got a "system software from developer was blocked from loading".
2. successfully allowed it (no issues with invisible or inactive "Allow" button)
3. now every time i open Karabiner it says that system policy prevents loading the kernel extension...

1. but there aren't any new messages/requests in System Preferences about blocked software / developers

• i've tried resetting the Gatekeeper with sudo spctl --reset-default -- didn't work
• i've tried whitelisting Karabiner from Gatekeeper with spctl --add /Applications/Karabiner-Elements.app -- didn't work

am i stupidly missing something or is this some kind of a bug?

EDIT: i have also tried getting the project from git and building it on my own, but it seems it's still built with the same developer id.
or at least it still didn't ask me for "System software from developer..." permission..

I have exactly the same bug. Only on my private laptop. Not om my work laptop. Both run Macos 10.14.3. Rebooting did not help

I was having this issue with the same version, it seems having chrome open when you go to authorise the application prevents you from clicking the button.

Hope this helps, solution was found in link below. :)

[Popl7]

Thx for the tip, but I think this is not the same issue we have.
There is no button shown.
(also Chrome is not opened op my computer)

I’m experiencing the same issue. After a reboot, I got the Karabiner-Elements Alert, but no button to allow karabiner. Until yesterday, karabiner was working just fine.

I’ve tried to reinstall according to the karabiner elements documentation. Unfortunately to no avail.

• macOS 10.14.4
• Karabiner Elements 12.2.0

[hovzik]

ok, i'm not sure what might be the problem / solution here, but my mac got updated to 10.14.4 yesterday and Karabiner just worked without any errors or messages or popups.

[Popl7]

I just updated my MacOS to 10.14.4 and this did not help me.

Any luck @Popl7 ? I'm having the same issues as well on my work macbook (currently running 10.14.3). I've tried everything including booting in safe mode but just don't see the "System software from developer..." message and button.

[hovzik]

i'm not sure if that'll help in any way but i've been trying various "solutions" i've found on the web..
spctl --remove --label "org.pqrs.Karabiner-Elements.Preferences"
spctl --remove --label "Karabiner-Elements" /Applications/Karabiner-Elements.app
sudo spctl --reset-default
those are all separate commands and i've tried all of them.. though, unfortunately, i don't know which one (if any) has helped..

[Popl7]

@mikowl no, sadly not.
I get the following errors when running spctl:

spctl --remove --label "org.pqrs.Karabiner-Elements.Preferences"
error: unknown error 99999=1869f
spctl --remove --label "Karabiner-Elements" /Applications/Karabiner-Elements.app
/Applications/Karabiner-Elements.app: unknown error 99999=1869f

I will try a reboot and running the commands in Recovery mode

[Popl7]

I have it working by deleting:
/Library/Application Support/org.pqrs
~/Library/Application Support/Karabiner

Hopefully this also works for you?

[Popl7]

I spoke too soon. Karabiner Elements starts up now. But it does not list any devices. Key changes also have no effect.

Uninstalling also did not work. I removed all Karabiner apps, settings, cache that I could find. Rebooted and reinstalled. I am now stuck again on the security button screen without any button for Karabiner and I cannot start Karabiner

[manuelhubacher]

@hovzik and @Popl7: thanks for the hints. As in @Popl7’s case, they didn’t work for me. The Karabiner-Elements Alert is all I get.

While Karabiner-Elements started up, I got the following message in the log:

[info] [grabber] kextload exit status: 71

The strange thing is that everything works just fine on my other machine (iMac, macOS 10.14.4). Any more ideas?

[manuelhubacher]

I got Karabiner-Elements working again by adding the team identifier G43BCU2T37. (Thanks @begatsby for the hint. See #1800.) At first, spctl wouldn't save the new configurations. So I started my mac in recovery mode, opened the terminal and added the team identifier in recovery mode with spctl kext-consent add G43BCU2T37. Maybe it helps you, @Popl7?

[Popl7]

@manuelhubacher thx for the tip. This did work for me. I can now use Karabiner Elements on this laptop too :-)

[mikowl]

Thanks @manuelhubacher - that worked for me as well.

@manuelhubacher Yesterday I ran into the same issue for no reason. It's been driving me nuts for a whole day. Your solution saved my day!!!!

does not work for me on
catalina 10.15.6 (19G2021)
karabiner 13.0.0

[tekezo]

@nerdfiles kext-consent has no effect with Karabiner-Elements v13.0.0, because v13.0.0 does not use kext.

If macOS Catalina Note #1 on this following page does not solve issue, please use Karabiner-Elements v12.10.0 until upgrading to Big Sur.
