It is completely done already in #4242. Just needs the final touches for the remaining build steps.

#4242 will be merged soon. Everyone who wants to give it a shot already can find the test binaries and signatures here: https://www.dropbox.com/sh/bos203ga9bq0akp/AAB6j5DPAINCPbCP9vyRB3n-a?dl=0 This version is based on v1.6.2. Please let me know if you still run into any issues on macOS when installing this version. Thanks!
