Apple ARM binary codesign issue

[Michael Dickens]

I have macOS 11.0beta7 installed : check!

Compare / contrast ARM Mac versus MacBook Pro 16 : check!

I have Xcode 12.2 beta installed : check!

I've removed "/Library/Developer/CommandLineTools" : check!

I hope that Apple fixes their toolchain to work without such intervention : check!

Do you know that best way we can complain to Apple to fix the toolchain?

Still doesn't work for me ... those specific files are almost the only ones that just don't respond to codesign. I'll try reinstalling from scratch ... maybe ports built with Xcode 12.0 don't entirely work with those built using 12.2beta? Hmmmm ....

Thx! - MLD
