Hello,

Does universal apps work on macOS 10.9 or is there any minimum OS requirement.

The minimum OS our app is supported is Mac OS 10.9, and we plan to support from OS 10.9 to macOS 11 for both Intel and AppleSilicon using a single package.

Once ported to Apple Silicon, and have the Universal binaries created, will these universal apps work on Mac OS 10.9

I don't see why they would not. the Universal/Fat Binary format does not seem to have changed, so as long as you have a valid x86_64 slice in your app, any "unknown" architectures should be ignored. Heck, you could include a PowerPC slice and run on 10.0, probably ;)
