Keep Missive up to date on your Mac
Missive 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 Missive gets updated
Floodtide reads the Homebrew catalog, a community-maintained index of Mac software, to learn which version of Missive 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.
- Missive 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 Missive 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.
Questions about Missive
Does Floodtide update Missive?
Yes. Missive is in the Homebrew catalog that Floodtide reads, so it appears in your update list automatically when a newer version is published, with no configuration.
How does Floodtide install a new version of Missive?
It downloads the vendor's official build, verifies it against the checksum the catalogue publishes, quits Missive if it is running, swaps the bundle, and keeps the previous version for seven days so the update can be undone.
Will updating Missive lose my settings?
No. Floodtide replaces the application bundle only. Preferences, licences and documents live outside it and are untouched.
