Mac Login Items Errors — Startup Apps Not Opening or Causing Slow Boot

Fix macOS login item errors including apps not launching at startup, slow boot from too many login items, and removing unwanted startup applications. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Login Items are apps, scripts, and services that launch automatically when you log in. macOS Ventura+ moved login item management to System Settings > General > Login Items. Background items (system extensions, launch agents/daemons) are now shown separately. Too many login items significantly increase boot time and memory usage. Some apps install login items silently during installation. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Too many apps configured to start at login, consuming resources during boot. Login item pointing to a moved or deleted application. Launch agent/daemon plist file misconfigured or corrupted. App's helper tool registered as a login item without user awareness. Third-party app installer adding background items without explicit consent. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Review login items: System Settings > General > Login Items & Extensions. Remove unwanted items: toggle off items you do not need at startup. Check launch agents: ls ~/Library/LaunchAgents/ and /Library/LaunchAgents/ for third-party plists. Remove a launch agent: launchctl unload ~/Library/LaunchAgents/com.example.agent.plist then delete the file. Identify which app installed an unwanted login item: check the plist file's Label and Program fields. If a login item keeps reappearing: the parent app may re-register it — check the app's preferences for an 'Open at Login' setting. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
