It'd be nice if there was a prebuilt binary of rg that ran without Rosetta 2 on ARM Macs. There could either be a separate macOS-arm binary, or there could be a single universal binary that runs on both ISAs.

rust-lang/rust#73908 covers support for this in upstream rust. This feature request is probably blocked on that completing.

https://github.com/shepmaster/rust/blob/silicon/silicon/README.md has some notes on cross-compiling.
