Reset macOS Without Losing Data
✅ Step 1: Back Up Your Data (Just in Case)
Even though this method preserves your files, it’s always smart to create a backup.
• Use Time Machine (built-in macOS backup tool)
• Or copy important files to an external drive / cloud storage
✅ Step 2: Sign Out of Apple Services
To avoid issues during reset:
• Go to System Settings (or System Preferences)
• Sign out of:
• Apple ID (iCloud)
• iMessage
• FaceTime
✅ Step 3: Use “Erase All Content and Settings” (macOS Monterey or Later)
If you're on macOS Monterey or newer:
1. Click the Apple menu ()
2. Go to System Settings / System Preferences
3. Select General → Transfer or Reset
4. Click Erase All Content and Settings
👉 This option removes system settings and apps but keeps your macOS intact, making it the easiest reset method.
✅ Step 4: Follow the On-Screen Instructions
• Enter your admin password
• Confirm the reset
• Your Mac will restart and begin the process
✅ Step 5: Reinstall macOS (Without Disk Erase)
If you want a deeper reset but still keep files:
1. Restart your Mac
2. Press and hold:
• Command (⌘) + R (for Intel Macs)
• Power button (for Apple Silicon Macs)
3. Enter macOS Recovery Mode
4. Select Reinstall macOS
5. Choose your current disk (DO NOT erase it)
👉 This reinstalls the OS while keeping your personal files intact.
✅ Step 6: Restore Settings & Apps
After reset:
• Reinstall apps if needed
• Sign back into Apple services
• Adjust system settings
⚠️ Important Tips
• Do NOT use Disk Utility → Erase unless you want a full wipe
• Ensure your Mac is plugged into power during the process
• Stable internet is required for reinstalling macOS
🎯 When to Use This Method
• Slow performance issues
• System bugs or glitches
• Preparing for a “soft reset” without losing files
