Apple M1\/Apple Silicon\/arm64 macOS can run x86_64<\/code> programs via Rosetta and most M1 systems currently (~March 2021) very likely run a mix of x86_64<\/code> and arm64<\/code> processes.<\/p>\n

Activity Monitor can show the architecture:<\/p>\n

\"\"<\/a><\/p>\n

but command line tools such as ps<\/code> and top<\/code> do not due to Apple hiding the details of the proper sysctl()<\/code> incantations necessary to get this info.<\/p>\n

Patrick Wardle reverse engineered Activity Monitor \u2014 https:\/\/www.patreon.com\/posts\/45121749<\/a> \u2014 and I slapped that hack together with some code from Sydney San Martin \u2014 https:\/\/gist.github.com\/s4y\/1173880\/9ea0ed9b8a55c23f10ecb67ce288e09f08d9d1e5 \u2014 into a nascent, bare-bones command line utility: archinfo<\/code>.<\/p>\n

It returns columnar output or JSON (via --json<\/code>) \u2014 that will work nicely with jq<\/code> \u2014 of running processes and their respective architectures.<\/p>\n

Build from source or grab from the releases via my git (https:\/\/git.rud.is\/hrbrmstr\/archinfo) or GH (https:\/\/github.com\/hrbrmstr\/archinfo).<\/p>\n

UPDATE 2021-03-14<\/h3>\n
My original goal was to use Swift for this, but it dawned on me that the vast majority of the codebase is in C, so I’ve removed the Xcode dependency and simplified the build process.<\/p>\n
The updated code also now defaults to columnar output. Use --json<\/code> to return ndjson output.<\/p>\n","protected":false},"excerpt":{"rendered":"
