I've spent too much of the last few days trying to figure out why I couldn't get Google File Stream running on a new account on a mac. I tried all of the recommended solutions with no luck so finally I decided to try to figure it out myself and I did get it working.
The problem I was seeing is that I was just getting an error every single time I tried to run the application. All I'd get was "drive file stream has encountered a problem and has stopped" and I couldn't change any preferences at all or do anything besides quit the app.
What fixed this issue for me (after trying everything else recommended online) was to uninstall Google File Stream, and then in finder show hidden files on the HD (cmd + shift + .) and go to Volumes and delete the Google Drive volume. Then I reinstalled Google File Stream, and once that was done it started working just fine the next time I fired the program up.
My guess is that the volume is created under the context of the user who installs the program, and if another account gets created it doesn't have permissions to access that volume. Purely a guess though. Anyway I hope that helps anyone who is running into this same issue.
