How to update Amazon Photos on your Mac

Amazon Photos is published as the Homebrew cask amazon-photos. Below is how to run that update yourself, then how Floodtide does it for you, alongside every other app on the Mac. Homebrew describes Amazon Photos as "Photo storage and sharing service".

Update Amazon Photos by hand

  1. Upgrade the Homebrew cask. If you installed Amazon Photos with Homebrew, open Terminal and run brew upgrade --cask amazon-photos. Homebrew downloads the current build and replaces the app in your Applications folder.
  2. Or download it from amazon.com. Otherwise get the current build from amazon.com, which is the same download Homebrew points at. Quit Amazon Photos, open the download and put the new Amazon Photos 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 amazon-photos

That 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 reads the same Homebrew record for Amazon Photos that the brew command above does, without needing Homebrew installed, to learn which version 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 developer signature of the installed copy; Gatekeeper must accept it before anything is replaced.
  • Amazon Photos 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.

Amazon Photos' publisher does not publish a checksum, so Floodtide verifies each download by requiring the same developer signature as the copy already installed, and Gatekeeper has to accept it before anything is replaced.

If Amazon Photos 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 Amazon Photos

Does Floodtide update Amazon Photos?

Yes. Amazon Photos 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 Amazon Photos?

It downloads the vendor's official build, verifies it carries the same developer signature as the copy already installed and passes Gatekeeper, quits Amazon Photos if it is running, swaps the bundle, and keeps the previous version for seven days so the update can be undone.

Will updating Amazon Photos lose my settings?

No. Floodtide replaces the application only. Preferences, licences and documents live outside it and are untouched.
