I’ve been relying on the Hyperkey app to allow for the easy keyboard shortcut “CMD-SHIFT-CNT-OPT”… it seems to not be working after upgrading to 15.4. Anyone else seeing this?
It’s working fine for my using Karibiner, what app are you using to configure the hyper-key as that could be the issue.
Maybe this one?
Duh, should have read it after my first coffee 
For a while, I used Karabiner for my hyper key. It started having problems, so I switched that function to the free Hyperkey app. Now, the reverse happened, and Karabiner is working well for hyper key:
- Karabiner Settings > Complex Modifications > Add predefined rules:
- Change right_shift + left_shift to caps_lock
- Change caps lock to hyper key
It’s working great now. I tap both shift keys to toggle caps lock. There’s also a predefined rule “Change double tap right shift key to caps lock” if you prefer that to tapping both shift keys.
