Did you contact Apple support? You paid one of the richest companies in the world for MacOS but khal is maintained by (mostly one) volunteer(s) free of charge (though you can offer to sponsor them, if you want) in their freetime.

That said, I did use khal on MacOS (M1 MacBook Pro) until the end of last year (installed via homebrew) and never had any issues.
So maybe if you provide some more information, somebody else will still be able to help you troubleshoot this.

Hello, Mr. Mschilli87
I quoted the error message, pal.

[mschilli87]

Well, it is certainly not enough for me to tell why you get this error when I didn't on a very similar environment. Have you tried different versions? Does the same config work on another OS? Did it work before or did is this your first attempt to run khard? If the former, when did it start failing? What is your configuration? ... 🤷🏻

But feel free for another volunteer to find time and motivation to help you. I tried. I'll spend my time elsewhere now.
