Recovery Mode

Recovery Mode is your emergency toolkit when things go wrong.

How to Enter Recovery Mode

1. Shut down your Mac
2. Press and hold the power button until "Loading startup options" appears
3. Click Options > Continue

What You Can Do

Tool	What It Does
Restore from Time Machine	Restore your Mac from a backup
Reinstall macOS	Download and install a fresh macOS (doesn't erase files)
Disk Utility	Repair disk errors, erase drives, partition
Safari	Browse Apple Support for help
Terminal	Advanced command-line troubleshooting

Reinstalling macOS

1. Enter Recovery Mode
2. Select Reinstall macOS Tahoe
3. Follow the prompts

This installs a fresh copy of macOS while keeping your files, apps, and settings. It's the equivalent of a "repair install."

Erasing and Starting Fresh

If you need a completely clean start:

1. Enter Recovery Mode
2. Open Disk Utility
3. Select your internal drive (Macintosh HD)
4. Click Erase (choose APFS format)
5. Close Disk Utility
6. Select Reinstall macOS

Warning: This erases everything. Make sure you have a Time Machine backup first.
