How to update Synkmark on your Mac
Synkmark publishes its updates through a Sparkle feed, the updater built into the app. Below is how to run that update yourself, then how Floodtide does it for you, alongside every other app on the Mac.
Update Synkmark by hand
- Check for Updates inside Synkmark. Open Synkmark, open the Synkmark menu beside the Apple menu and choose Check for Updates. Sparkle, the updater built into the app, downloads the new version, verifies it and relaunches Synkmark on it.
- If nothing is offered. Sparkle reads the feed at sheepsystems.com on the schedule set in Synkmark's preferences, so a build that is out may not be offered until the next check. The menu item forces one now.
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 Synkmark'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.
- Synkmark is asked to quit politely if it is open, and never forced.

Questions about Synkmark
Does Floodtide update Synkmark?
Yes. Synkmark also ships its own updater, so it can keep itself current when you launch it. Floodtide covers it anyway, because a self-updating app only updates when you happen to open it, and it tells you nothing about the other apps on the Mac. Floodtide shows Synkmark beside everything else and updates the whole set in one pass.
How does Floodtide install a new version of Synkmark?
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 Synkmark if it is running and puts the new version in place.
Will updating Synkmark lose my settings?
No. Floodtide replaces the application only. Preferences, licences and documents live outside it and are untouched.
