I don't know, I'm currently using CHIRP on my M1 MBA running Big Sur 11.5.2 and programming the 8 radios I have from Baofeng to Wouxun with custom channel lists, scan groups and even setting radio features. CHIRP is awesome software, and while it's not perfect, no software is, but it's certainly quite capable and better than what has been supplied to me by the various manufacturers of my radios. Sorry to hear you're having so much trouble, but whineing, acting entitled, and shitting on this list certainly isn't going to solve your problems.
Basically you’ve said it all - You get what you pay for!
You on the Titanic dodging icebergs in the North Atlantic without a compass.
The tragedy of it all is that you’re wasting time and your own money and producing nothing.
