Bootable Installer

For advanced recovery scenarios, create a bootable macOS installer:

1. Download macOS from the App Store (search "macOS Tahoe")
2. Get a 16GB+ USB drive
3. Open Terminal and run:

sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

1. Replace /Volumes/MyVolume with your USB drive's name

This gives you a standalone installer that works even without internet.
