How to update Microsoft Teams on your Mac
Microsoft Teams is published as the Homebrew cask microsoft-teams. Below is how to run that update yourself, then how Floodtide does it for you, alongside every other app on the Mac. Homebrew describes Microsoft Teams as "Meet, chat, call, and collaborate in just one place".
Update Microsoft Teams by hand
- Upgrade the Homebrew cask. If you installed Microsoft Teams with Homebrew, open Terminal and run
brew upgrade --cask microsoft-teams. Homebrew downloads the current build and replaces the app in your Applications folder. - Or download it from microsoft.com. Otherwise get the current build from microsoft.com, which is the same download Homebrew points at. Quit Microsoft Teams, open the download and put the new Microsoft Teams in Applications in place of the old one: a disk image is dragged across, an installer package runs its own steps. Your settings and documents live outside the app and are kept.
brew upgrade --cask microsoft-teamsThat is one app. The same walk, through a different menu or page each time, is what every other app on the Mac asks of you, which is where Floodtide comes in.
The shorter route: one click in Floodtide
Floodtide's own signed catalog lists where Microsoft Teams' developer publishes each release, and Floodtide reads that source directly to learn which version is current. When yours is behind, the row appears under Updates with the version that is out, next to every other app on the Mac that is behind.
- The developer's own build is downloaded, with real progress.
- It is checked against a checksum where the source publishes one, otherwise against the developer signature of the copy already installed, and Gatekeeper has to accept it before anything is replaced.
- Microsoft Teams is asked to quit politely if it is open, and never forced.

Questions about Microsoft Teams
Does Floodtide update Microsoft Teams?
Yes. Microsoft Teams is in Floodtide's signed catalog, which reads Microsoft Teams' own release source, 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 Microsoft Teams?
It downloads the developer's own build and checks it before anything on your Mac changes: against a checksum where the source publishes one, otherwise by requiring the same developer signature as the copy already installed, and Gatekeeper has to accept it. Then it quits Microsoft Teams if it is running and puts the new version in place.
Will updating Microsoft Teams lose my settings?
No. Floodtide replaces the application only. Preferences, licences and documents live outside it and are untouched.
