4663	Make native Apple M1 CPU distribution	Tom Goddard	Zach Pearson	"Apple is replacing Intel CPUs in all machines with ARM cpus.  Already have Mac laptop and Mac Mini models with ARM (Apple M1) cpu since late 2020.  Apple M1 CPU is 5 nm process vs 10 nm for latest Intel cpus so much more energy efficient, or higher performance at comparable energy.

Macs use Rosetta 2 to run Intel apps on ARM cpu machines.  This seems to be working fine for ChimeraX.  Native ARM ChimeraX may give higher performance.  Python is reported to run up to 3 times faster on ARM cpu vs Intel emulation on Mac.

We proposed making native ARM version in Chan-Zuckerberg Science Initiative (CZI) Essential Open Source Software proposal submitted May 15, 2021 with possible funding date Sept 1, 2021.
