Desktop updates

Replace an installed copy and verify the local engine after an upgrade.

Updated 22 July 2026Applies to 0.2.8 release

Current update flow

Use the newer signed DMG and replace the existing app in Applications. The desktop does not document an unfinished partial updater as an available feature.

Engine compatibility

At launch, OpenSS queries the local engine version and API version. An incompatible OpenSS-owned engine is terminated and the bundled engine is started before chat and capture become available.

Verify an update

  • Open About OpenSS and confirm the desktop version.
  • Send a normal message.
  • Capture a supported target.
  • Quit and reopen, then confirm only one active engine service is available.
