Closes #28044

Summary

Adds docs/tutorials/podman-macos-launchd-autostart.md — a comprehensive tutorial for automatically starting podman machine at login on macOS using launchd.

Why this was needed

There is widespread confusion online about how to do this correctly. The most common problem is that users set KeepAlive=true in their plist, causing an infinite restart loop because podman machine start forks a background daemon and exits, which launchd interprets as a crash.

What the tutorial covers

  • Complete, annotated plist for Apple Silicon and Intel Macs
  • KeepAlive=false and why it must be false (explicitly explained)
  • Starting a non-default named machine
  • Load / verify / unload instructions using both the legacy load/unload and newer bootstrap/bootout APIs
  • Troubleshooting section for the four most common failure modes:
    1. Restart loop from KeepAlive=true
    2. Wrong podman binary path
    3. Race condition between machine start and socket availability (with a retry snippet)
    4. Log file permission issues
  • Pointer to Quadlet for auto-starting containers once the machine is up

Testing

Tested on macOS Sequoia 15.x with:

  • Apple Silicon (M-series, Homebrew at /opt/homebrew)
  • Podman 5.x with applehv VM type

Made with Cursor

Add a comprehensive guide for automating podman machine start via
launchd (the macOS equivalent of systemd) so that the Podman VM is
already running when the user sits down at their machine.

The tutorial covers:
- Why KeepAlive must be false (the most common cause of the
  restart-loop problem reported by users online)
- A complete, annotated plist file for both Apple Silicon and Intel
- Step-by-step load/verify/unload instructions
- Adjustments for non-default machine names
- Troubleshooting section for the most frequent failure modes:
  - restart loop from KeepAlive=true
  - wrong podman binary path
  - race between machine start and socket availability
  - log file permission issues
- Pointer to Quadlet for auto-starting containers once the machine
  is up

Closes containers#28044

@turanalmammadov need signoff on your commit to pass the DCO check.

I should've mentioned that before the LGTM. My bad.
