Hi. Yes, not signed. We don’t yet actually provide packages for MacOS, just binaries.
Here are two things that can help:
Add an exception for Manticore apps:
In the Finder locate the app you want to open: searchd, indexer etc.
Control-click the app icon, then choose Open from the shortcut menu
Click Open
The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it or from cli, just as you can with any authorised app
Sure, we should eventually pack that as a .dmg and sign it properly. It’s just that not many people are using Manticore on Mac and there’s also HomeBrew.
