Since Pearcleaner writes the plist to `~/Library/LaunchAgents/`, and that path resolves to `/Volumes/<DriveName>/Users/<username>/Library/LaunchAgents/`, launchd rejects it. The actual error from `log show`: ``` Caller specified a plist with bad ownership/permissions: path = /Volumes/<DriveName>/Users/<username>/Library/LaunchAgents/com.alienator88.Pearcleaner.homebrew-autoupdate.plist ``` **Suggested fix:** Detect that `$HOME` is on a non-boot volume and write the plist to `/Library/LaunchAgents/` (system-level) instead, with `root:wheel` / `644` permissions. #### Steps: 1. Have home directory on a non-boot volume (e.g. `/Volumes/<n>/Users/<username>/`) 2. Enable Homebrew auto-update scheduling in Pearcleaner 3. Observe "Failed to register LaunchAgent: Bootstrap failed: 5: Input/output error" #### Screenshots: N/A #### Debug Console <pre> N/A </pre> #### Console Logs <pre> N/A </pre>
