Probably relevant, though I’m not 100% sure where the illegal instruction comes in as that’s a CPU and not OS thing: Mac OS 10.6.8 32 bit crash, v0.14.41
I’m still open to making the 32 bit Mac build special as it’s only reason for existing is compatibility with obsolete unsupported machines. But no one has so far said “yeah, please do that, that would be great” and as Audrius says it implies extra work and oddness.
