Google Drive File Stream

I tried the above but no message is displayed on "Security & Privacy" --> General for any blocked apps. I've tried uninstalling and deleting the cache files as per this article https://support.itsolver.net/hc/en-au/articles/115005123203-Google-Drive-File-Stream-encountered-a-problem-and-has-stopped but it's still being blocked.

Certainly a bug and issue. I was able to fix by rebooting and then when Google Drive File Stream warns of extension blocked, use that dialog box and "Go to System Preferences" button, then General tab. Only in this manner does it ask or display an "Allow" button.

In previous attempts, I just skipped that box and went to System Preferences, Privacy & Security myself, but then doesn't show any developer being blocked message(s).

The short of it: close any other instances you have of System Preferences open, reboot if necessary and then use the Google Drive File Stream dialog box to get there, and it will hopefully present the "Allow" button.

Issue is not fixed. I went to Privacy and Security / General and clicked on the allow button. Then I rebooted (twice). And I'm still getting the "encountered a problem and has stopped. There is no longer a dialog box to click.

Same problem.

I had to reboot, and then immediately go to the Security > General pane, and there was the message about Google, and an Allow button, that wasn't there before I rebooted. That appears to have worked.

I work as an IT support engineer looking after almost 1,000 Macs and we have had this issue. For some unknown reason, kernel extensions have become unloaded or disallowed. This is affecting High Sierra as well as Mojave, they all started with Gatekeeper Configuration Data version 166 update. We have lots of other affected software such as Sophos, Wacom, Epson print drivers, HP print drivers, Solarflare and Sonnet 10GbE card drivers, Dropbox, VMWare Fusion, Parallels, just to name some we've had issues with. On 10.13 and 10.14 were experiencing the same issue, the Allow button in Security and Privacy is not appearing. Our only solution has been to push out kernel extension whitelisting out via MDM, this is an enterprise only approach and requires a signed MDM certificate and Apple push notification services, if any macadmins are reading this, this is your solution.

Google File Stream had another issue a week prior where Google renamed a kernel extension from com.google.dfsfuse.filesystems.dfsfuse to com.google.drivefs.filesystems.dfsfuse which has caused everyone to have to allow this new extension. People currently can't allow it as the button is missing in Security and Privacy.

I didn't have to reboot, but did have to quit Google Drive and restart the application. That was the only way I could find to prompt the "allow Google" tab on the Security & Privacy --> General tab.

I am having this same problem but when I connect to "Security & Privacy" there is no "allow" button. Desperately need to solve this, and help would be much appreciated.

I'm having the same issue as @ggwells and @pscimolai. This question IS NOT solved.

Made the same attempts as mentioned here. Tried it in a new user account on the same Mac and it worked.

Something within the user account has gone awry...not sure what it could be yet.

Worked perfectly. Thank you!

Hmm...

Should we be worrying why Google needs such high access to our entire systems, just to manage a few files?

Why is this extension not already signed by Apple?
