This is an addition to the last post on the Hyper Key and Shortcuts. There are a few shortcuts from macOS that already make use of the Hyper Key:

• cmd + option + ctrl + shift + . : Will run the system diagnostics on macOS. This will use up resources from your system and also waste a lot of disk space in /var/tmp
• cmd + option + ctrl + shift + , : Will open the most recent system diagnose in the Finder.
• cmd + option + ctrl + shift + w : Will run the Wi-Fi diagnostics – also using a lot of space.

An Apple StackExchange Thread helped me figure this out. Causing my manually defined shortcuts to fail inconsistently. But I wasn't able to find a way to disable this in macOS directly.

But I found a workaround: Assigning these key combinations to the f17 - f19 keys. 🎉 Those are in general not used by macOS, and so far, I didn't run into any complications.

Below the relevant part of my karabiner config:
