We have now had 3 reports of this error. #8893 was also Antechamber, and #10132 was ffmpeg. All 3 are on M2 CPUs. It may be that the newer Apple M2 machines do not have Rosetta installed by default.
In any case we are probably going to have to replace all our Intel-only third-party binaries with universal binaries (or ARM only) in the future when Apple drops Intel support. That could be the distant future, and if we wait until Apple drops Intel support, we may also drop ChimeraX on Mac Intel and then we would only need ARM binaries which would be simpler.
Should probably survey what Mac Intel-only binaries we are including in the distribution. Possibly the universal build lipo script logs all those and we could find them by looking at the lipo script log.
