How to update KeychainCheck2 on your Mac
KeychainCheck2's developer publishes each version on their own page at eclecticlight.co. Below is how to run that update yourself, then how Floodtide does it for you, alongside every other app on the Mac.
Update KeychainCheck2 by hand
- Download the current build from eclecticlight.co. KeychainCheck2's developer publishes each release at eclecticlight.co. Get the Mac build from there.
- Replace the old copy. Quit KeychainCheck2, open the download and put the new KeychainCheck2 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.
The shorter route: one click in Floodtide
Floodtide's own signed catalog lists where KeychainCheck2'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.
- KeychainCheck2 is asked to quit politely if it is open, and never forced.

Questions about KeychainCheck2
Does Floodtide update KeychainCheck2?
Yes. KeychainCheck2 is in Floodtide's signed catalog, which reads KeychainCheck2's 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 KeychainCheck2?
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 KeychainCheck2 if it is running and puts the new version in place.
Will updating KeychainCheck2 lose my settings?
No. Floodtide replaces the application only. Preferences, licences and documents live outside it and are untouched.
