Racket now builds and runs on M1 Macs using a Git repo checkout. If all goes well, snapshots will appear tomorrow at the Utah snapshot site linked at
https://snapshot.racket-lang.org/ Meanwhile, I've uploaded an image here (link will last a few days): https://www.cs.utah.edu/plt/snapshots/20201205-10ea287/installers/racket-7.9.0.10-aarch64-macosx-cs.dmg Yes, the M1 MacBook Pro is pretty fast --- about x1.5 as fast as a 2018 i7 MacBook Pro for tasks that aren't primarily about loading files: i7 M1 racket -n 0.08s 0.07s racket -l racket 0.27s 0.25s racket -cl racket/base 2.50s 1.60s shootout mandelbrot.rkt 1.40s 0.94s racket -l drracket ... -e '(exit)' 4.42s 2.79s make base in fresh Git clone[1] 7m02s 5m02s raco setup[2] 21m08s 14m48s [1] After `make pb-fetch` to avoid network time [2] After `make`, `raco setup --clean`, and `rm -r racket/docs` Since we had an AArch64 backend for Chez Scheme, porting Racket CS was mostly straightforward. Racket BS also works, but there's no AArch64 JIT in BC, so it can be slow. Some work was needed to conform to W^X requirements (i.e., can't make memory both executable and writable at the same time), but unlike other W^X environments that I've tried to use, the OS provides good support for code-generating programs. Building third-party libraries like Cairo went better than expected. I spent most of my porting time and effort being confused about aspects of code signing, but it seems reasonable enough in the end.
