Mac App Store沙箱应用退出后自动重启问题排查求助

Hey there, sorry to hear you're stuck with this confusing auto-restart problem—sandboxed apps shouldn't be able to initiate their own restart after a user explicitly quits them, so this is definitely worth digging into. Here are actionable troubleshooting angles to help you narrow down the root cause:

System-Level Triggers #

• Check if your app is listed in the user's Login Items (System Settings > General > Login Items). While sandboxed apps require user approval to add themselves here, it's possible users accidentally added it, or a third-party tool did so on their behalf.
• Rule out third-party automation tools (like Alfred, Hazel, or Keyboard Maestro) that might be triggering your app to launch again after quit. Ask users if they have any workflows or scripts that interact with your app.
• Use this terminal command to check for unexpected launch daemons/agents linked to your app:

  launchctl list | grep YourAppBundleID
  

  Sandboxed apps can't register these without explicit entitlements, but it's worth verifying no rogue entries exist.

Background Task Misconfiguration #

• If your app uses BGTaskScheduler or the older NSBackgroundTaskScheduler, double-check that you're properly marking tasks as completed with setTaskCompleted(success:). Failing to do this might cause the system to re-launch your app to finish incomplete tasks.
• Confirm you've only requested necessary background entitlements (like com.apple.security.background-task) and haven't accidentally included permissions that allow auto-launch (e.g., com.apple.security.background-auto-launch, reserved for specific use cases like Bluetooth accessory triggers).

Crash vs. Intentional Restart #

• Users might confuse a crash-and-auto-restart with a post-quit restart. Guide them to pull system logs using this command to clarify the launch reason:

  log show --predicate 'process == "YourAppName"' --info --last 1h
  

  Look for entries indicating Termination Reason (normal quit vs. crash) or Launch Reason (whether the system initiated the launch).

User Environment Variables #

• Collect targeted details from affected users to narrow down environmental differences:
  • Exact macOS version (different releases have subtle sandbox behavior changes)
  • How they're quitting the app (Cmd+Q, Dock right-click > Quit, Force Quit via Activity Monitor)
  • Whether they have "Automatic Login" enabled in Users & Groups settings
  • Any other apps/extensions they're running that might interact with system launch processes

App State Handling #

• Review your app's quit logic: Are you saving any state that might be misinterpreted by the system? For example, if you're restoring windows on launch, ensure that a user-initiated quit properly disables this behavior (check NSApplication's shouldTerminateAfterLastWindowClosed setting if applicable).
