After updating my Mac to MacOS Mojave 10.14.5 (18F108f) I cannot open Drive File Stream and can't "allow" in Security & Privacy, because previously I've already did it before few years ago. There is no option "allow" now and Drive File Stream can't be opened.

I believe this is a beta-release of OSX? That means things are going to break. I would keep watching for updates, or otherwise rollback to the previous supported version of OSX.

I'm facing the same issue as well.

Yes, This is Beta Version, but before with other beta versions was everything ok. Maybe I can reinstall Drive File Stream, but from the beginning with this certificate to "allow" in Security & Privacy setting?

Clovis Museux's solution on 4/23/19 worked perfectly for me.  I'd tried all the other solutions in this forum, amongst other things.  But using the specific terminal command in Recovery Mode is what ultimately worked in my case.

I am running 10.15 Catalina Beta operating system and version of File Stream.
