That’s why it’s important to make some sort of emergency backup for that “oh sh*t” situation.

Here’s how:

1. First, download the full MacOS Tahoe installer here.
2. Connect a USB Flash Drive to your Mac.
3. Open Disk Utility (Finder > Applications > Utilities > Disk Utility).
4. Format the USB Drive.
5. Format it as Mac OS Extended (Journaled) with a GUID Partition Map, and name it something like TahoeUSB.
6. Now open Terminal, found from /Applications/Utilities or via Spotlight
7. Run the following command (see Appendix A).
8. Press [Return].
9. Enter your Administration Password when prompted.
10. Wait for the procedure to finish.
11. That’s it.

Appendix A:

sudo /Applications/Install\ macOS\ beta.app/Contents/Resources/createinstallmedia --volume /Volumes/TahoeUSB --nointeraction
