How iKnowMyMac updates Mixin Messenger Desktop

How it finds the update

1. Reads the latest release in the developer's GitHub repository.
2. Picks exactly one Mac build for Apple silicon or universal. If more than one file could be the right one, it does nothing rather than guess.
3. Checks the release's published digest when GitHub has one.

Checked before every install

• The code signature is valid and Gatekeeper accepts it, notarized if your copy was.
• It's signed by the same developer (team ID) as the copy you have. A change of developer asks you first.
• It's never signed worse than your copy, and never an older version.
• Your current copy is kept as a backup first, so Undo Last Update puts it back in one step.
• An app that's open is never quit for you: it updates when you quit it.
