Keep checkra1n up to date on your Mac
checkra1n is covered by Floodtide. It shows up in your update list the moment a newer version ships, and updates in one click along with everything else on this Mac.
How checkra1n gets updated
Floodtide reads the Homebrew catalog, a community-maintained index of Mac software, to learn which version of checkra1n is current. When yours is behind, the row appears under Updates with the version it will move to and the download size. Pressing Update, or Update All, does the rest:
- The vendor’s own build is downloaded, several apps at a time, with real progress.
- The download is verified against the checksum the catalogue publishes.
- checkra1n is asked to quit politely if it is open, and never forced.
- The bundle is swapped and the old version kept for seven days, so Undo Last Update always works.
- The replacement’s code signature is checked; a build signed worse than the one you had is rolled back automatically.
If checkra1n lives in a folder macOS protects, the swap asks for your administrator password once for the whole batch, exactly as the Finder does when you install anything by hand.
