How to update Apple2 on your Mac
Apple2's developer publishes each version on their own page at jwz.org, and the app can also update itself. Below is how to run that update yourself, then how Floodtide does it for you, alongside every other app on the Mac.
Update Apple2 by hand
- Let Apple2 update itself. Open Apple2. It checks for new versions on its own, and if it has not offered one yet, look in the Apple2 menu, or under Help or its preferences, for Check for Updates, then let it download and relaunch.
- Download the current build from the developer. Apple2's developer publishes each release on their own site, with the download itself served from jwz.org. Get the Mac build from there.
- Replace the old copy. Quit Apple2, open the download and put the new Apple2 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 Apple2'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.
- Apple2 is asked to quit politely if it is open, and never forced.

Questions about Apple2
Does Floodtide update Apple2?
Yes. Apple2 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 Apple2 beside everything else and updates the whole set in one pass.
How does Floodtide install a new version of Apple2?
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 Apple2 if it is running and puts the new version in place.
Will updating Apple2 lose my settings?
No. Floodtide replaces the application only. Preferences, licences and documents live outside it and are untouched.
