Steps to reproduce the issue:

On the Mac client:

Run "podman machine init".

$ ./podman machine init test
Extracting compressed file

Run "podman machine start", it will stop with an error.

I was able to start the VM by adding the QEMU option.

$ vi ~/.config/containers/podman/machine/qemu/test.json`

  "-accel",
  "hvf",

$ ./podman machine start test
Waiting for VM ...
$ ./podman machine list

Hypervisor.framework is supported on macOS

$ sysctl -a | grep kern.hv_support
kern.hv_support: 1

For some reason it is only added on arm64, but not on amd64: pkg/machine/qemu/options_darwin_arm64.go: "-accel", "hvf", pkg/machine/qemu/options_linux_amd64.go: "-accel", "kvm", pkg/machine/qemu/options_linux_arm64.go: "-accel", "kvm",

Note: this was in v3.2.0
