How to update Disk Jockey on your Mac
Disk Jockey is published as the Homebrew cask disk-jockey. Below is how to run that update yourself, then how Floodtide does it for you, alongside every other app on the Mac. Homebrew describes Disk Jockey as "Disk image creator and analyser for retro computers or emulators".
Update Disk Jockey by hand
- Upgrade the Homebrew cask. If you installed Disk Jockey with Homebrew, open Terminal and run
brew upgrade --cask disk-jockey. Homebrew downloads the current build and replaces the app in your Applications folder. - Or download it from diskjockey.onegeekarmy.eu. Otherwise get the current build from diskjockey.onegeekarmy.eu, which is the same download Homebrew points at. Quit Disk Jockey, open the download and put the new Disk Jockey 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.
brew upgrade --cask disk-jockeyThat 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 reads the same Homebrew record for Disk Jockey that the brew command above does, without needing Homebrew installed, to learn which version is current. When yours is behind, the row appears under Updates with the version it will move to and the download size. Pressing Update, or Update All, does the rest:
- The vendor's own build is downloaded, several apps at a time, with real progress.
- The download is verified against the developer signature of the installed copy; Gatekeeper must accept it before anything is replaced.
- Disk Jockey is asked to quit politely if it is open, and never forced.
- The bundle is swapped and the old version kept for seven days, so Undo Last Update always works.
- The replacement's code signature is checked; a build signed worse than the one you had is rolled back automatically.
Disk Jockey's publisher does not publish a checksum, so Floodtide verifies each download by requiring the same developer signature as the copy already installed, and Gatekeeper has to accept it before anything is replaced.
If Disk Jockey lives in a folder macOS protects, the swap asks for your administrator password once for the whole batch, exactly as the Finder does when you install anything by hand.

Questions about Disk Jockey
Does Floodtide update Disk Jockey?
Yes. Disk Jockey is in the Homebrew catalog that Floodtide reads, 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 Disk Jockey?
It downloads the vendor's official build, verifies it carries the same developer signature as the copy already installed and passes Gatekeeper, quits Disk Jockey if it is running, swaps the bundle, and keeps the previous version for seven days so the update can be undone.
Will updating Disk Jockey lose my settings?
No. Floodtide replaces the application only. Preferences, licences and documents live outside it and are untouched.
