How to update BatchPhoto on your Mac

1. Download the current build from batchphoto.com. BatchPhoto's developer publishes each release at batchphoto.com. Get the Mac build from there.
2. Replace the old copy. Quit BatchPhoto, open the download and put the new BatchPhoto 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.

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.

Floodtide's own signed catalog lists where BatchPhoto's 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.
• BatchPhoto is asked to quit politely if it is open, and never forced.
