Keep Playwrite US Modern Guides up to date on your Mac

Floodtide reads the Homebrew catalog, a community-maintained index of Mac software, to learn which version of Playwrite US Modern Guides 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.
• Playwrite US Modern Guides 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 Playwrite US Modern Guides 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.
