Yep I’m on 26.4 Beta 1 And yes, brightness does increase when I press ctrl+opt+cmd+shift + M ---

I just tried and can reproduce, capslock+m doesn’t trigger brightness, but cmd+ctrl+shift+opt+m does. My other hyperkey bindings seem to work fine, and if I set capslock+m to volume-up it also works 🫠 ---

Ah, then I think I know what causes this (it is pretty specific to the brightness actions). I will probably be able to solve it but I'll need to do some tests. //edit I believe this has always been like this because the brightness keys do not work while ctrl is pressed (they work, but they then change the brightness of the external display) ---

Haha yep, can confirm volume works for me too Thanks Andreas! ---

Another confirmation for the Hyperkey fix in latest alpha. Thanks so much @Andreas_Hegenberg. ---

I can confirm that the Hyper Key does not work as expected. _ **However** _, some strange bugs have popped up, and I cannot for the life of me figure out why they are occurring. It is true that when I press Caps Lock in a BTT input box, it registers as it should with all four modifiers. It also works correctly when I use my keyboard commands with the Hyper Key in combination with any letter, number, etc. However, the issue is that for some reason, when Caps Lock (Hyper Key) is double-clicked—or clicked after a previous click, perhaps leaving a key stuck or not fully released—it triggers Right Control + Right Control key sequence. I have that combination set to the Hyper Key's AI feature (Bring Your Own Key/API). It's very strange. I've been racking my brain and can't figure out why it would be doing that. Does anyone have any ideas? ---

That is most likely due to how the workaround works. You can use this command to switch to an alternate "workaround mode" which should prevent issues with right-ctrl key sequences: ```auto osascript -e 'tell application "BetterTouchTool" to set_user_defaults key "BTTHyperKeyUseAlternateMode" numberValue 1' ``` Possibly I'll make that the default mode ---

Apple resolved the issue in 26.4 beta 3, so I will disable the workaround again with the next alpha! [Previous page](https://community.folivora.ai/t/hyper-key-cannot-be-set-for-internal-built-in-macbook-keyboard-on-macos-26-4-beta-1/46312.md?page=1)
