macOS Troubleshooting settings
Reset, restart, and diagnose common issues.
- Erase & Reset MacErase All Content and Settings lets you wipe your Mac back to factory defaults — useful for major troubleshooting, or before selling, trading in, or giving away your device.
- macOS RecoverymacOS Recovery is a built-in set of utilities for reinstalling macOS, restoring from a Time Machine backup, repairing a damaged disk, and resetting a forgotten password — all accessible without needing a working copy of macOS already running.
- Safe ModeSafe Mode starts your Mac with only essential system software and drivers loaded, skipping login items, most fonts, and system caches. It's a diagnostic first step used to determine whether a startup problem is caused by third-party software or a deeper system issue.
- Analytics & ImprovementsAnalytics & Improvements controls whether your Mac automatically sends crash reports and usage analytics to Apple, and optionally to third-party app developers, to help them find and fix bugs. It's separate from location services and general privacy settings, focused specifically on diagnostic and usage data.
- Activity MonitorActivity Monitor is macOS's built-in tool for seeing exactly what's using your Mac's CPU, memory, energy, disk, and network resources in real time, broken down by individual app and process. It's the first place to look when the Mac feels slow, hot, or the fan is running loudly.
- Disk Utility First AidRun Disk Utility's First Aid tool to check a disk or volume for directory and file system errors and attempt automatic repair.
- Apple DiagnosticsUse Apple Diagnostics, launched at startup, to test your Mac's hardware components including memory, logic board, and battery for underlying issues.
- Console: View System LogsUse the Console app to view real-time and historical system logs, crash reports, and diagnostic messages generated by macOS and installed apps.
- Reinstall macOSReinstall the current version of macOS over your existing system through Recovery Mode, replacing system files while keeping your apps, settings, and personal data intact.
- Force Quit Unresponsive AppsUse the Force Quit Applications window to immediately close an app that has stopped responding, without needing to restart the entire Mac.
