How to update Astrill on your Mac
Astrill's developer publishes each version on their own page at astrill.com. Below is how to run that update yourself, then how Floodtide does it for you, alongside every other app on the Mac.
Update Astrill by hand
- Download the current build from astrill.com. Astrill's developer publishes each release at astrill.com. Get the Mac build from there.
- Replace the old copy. Quit Astrill, open the download and put the new Astrill 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 Astrill'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.
- Astrill is asked to quit politely if it is open, and never forced.

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