Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide? (https://github.com/containers/podman/blob/main/troubleshooting.md)

Yes

Additional environment details (AWS, VirtualBox, physical, etc.):

Upon further investigation, seems to be an issue with qemu 7.0.0 on OS X 12.3 as discussed in the linked qemu issue.

Was not able to repro on OS X 12.4

[rhatdan]

This seems to be an issue between OS X and Qemu, not something Podman can fix. Problem is fixed as everyone updatest to 12.4. I am going to close this issue, but conversation can continue here.

[akirilov]

Agreed with that resolution!
