[Pablion]

Occasionally = 13 of 30 times I tested worked, while others 17 times failed. And sometimes there was a prompt saying GIGABYTE Keyboard is ignored temporarily until {"key_code": "caps_lock"} is pressed again.

[tekezo]

Thank you for feedback!

It seems Karabiner-Elements process is crashed frequently.
Is there any crash log in Console.app > Crash Reports?

[leocassioo]

I have the same problem here. Version 13.0.0

[dotmanner]

After installing version 13, caps lock key does not work intermittently. But LED light works fine.
After installing version 12, the key works fine. But the led is not displayed.

[kepford]

After the update I see this. After approving the app it still fails. After quitting the app I see the same window again. It appears that approval is not sticking.

[metersk]

Chiming in to say that my modifier Change caps_lock to control if pressed with other keys, to escape if pressed alone. stopped working this morning. Hitting capslock only results in left_control, not escape.

type:key_down        code:224        name:left_control    misc:flags left_control
type:key_up          code:224        name:left_control    misc:

My guess is that it's related to this issue, but can create another issue if not.

edit: for some reason this is only happening on my macbook's keyboard. everything seems fine with my external keyboard.

[spenrose]

I also have caps_lock issue like @metersk. I have my caps_lock mapped to left_control. I am unable to caps_lock + space it results in only left_control.

[jesp010]

Same problem as @Pablion

[tekezo]

Thank you for feedbacks!

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 if you are using macOS 10.15.5 or earlier.
https://karabiner-elements.pqrs.org/docs/releasenotes/

Even if you're using macOS 10.15.6 or later, other issues of macOS may prevent DriverKit driver loading.
In this case, please try macOS Catalina Note #1 on this following page.
https://karabiner-elements.pqrs.org/docs/help/troubleshooting/driver-alert-keeps-showing-up/

[Pablion]

I've tested the downgrade method for a while. Seems all fine for me.
Please follow the instruction of @tekezo said. I believe this will resolve most of our problems. @jesp010
To downgrade, just install the old version https://karabiner-elements.pqrs.org/docs/releasenotes/, nothing more is needed.

This screen didn't show on my Mac so I am not sure if the downgrade will help.

I saw the same problem as this, but since it is a minor one, I didn't report it.

After installing version 13, the caps lock key does not work intermittently. But LED light works fine.

[seathasky]

revert to version 12, it fixes this issue.

[tekezo]

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

Now it works almost perfectly.
The LED indicator on my keyboard does not light up when turning on the Capslock. Just details, thank you!
