I've had issues as recently as this week with podman on an m1 laptop - the container would start but after a short time would freeze completely and couldn't even be killed - only solution i found was to restart my laptop. Eventually, I gave up and went back to using docker.
Yep, there's a thread with hundreds of people on M1,2,3 macs having issues, it bit some people at work on newer macs. If you installed it a while ago, it's fine, but if you installed recently, it's buggered. The solution was to install podman-desktop which was somehow packaged such that it's not getting the bug (podman machine start hangs forever).
