“Signboard” Not Opened Warning

[kimonostereo]

When I try launching Signboard on macOS 15.7.5, I get this message: Apple could not verify “Signboard” is free of malware that may harm your Mac or compromise your privacy. I tried several times and got that same message.

@kimonostereo Even though I notarize Signboard, I am distributing it outside of the App Store. So on macOS you have to set it to allow you to open apps like Signboard.

Take a look in Settings > Privacy & Security > scroll down to Security section and "Allow applications from" ... "App Store & Known Developers". You might also be able to see Signboard with a "Open Anyway" option there. But try opening Signboard again.
