Now, CI builds for macOS involve three separate builds for a range of macOS versions, and a final Universal macOS Binary made on Big Sur. It should work with the M1 chip and x86_64 Intel Macs.
I have also renamed osx_environment->macOS_environment.sh to reflect the new name change of Apple's desktop OS.
In terms of the clean_builds.sh script, this has also been refactored to be more resilient, and efficient (marginally).
