Match the published build ID before you allow a new OFDownloader installer through Gatekeeper or SmartScreen

A first-run warning from macOS Gatekeeper or Windows SmartScreen does not by itself mean the installer is unsafe. Pause before you click through, and match the published build ID to the file you just downloaded.

Open OFDownloader (by SaveMyDayApp) trust notes beside the warning dialog, then follow the verify-installer guide against that exact build.

If the build ID and hash match the published notes, you can allow the official installer through Gatekeeper or SmartScreen. If they do not match, discard the file and download again from the official site.
