Backup and Sync has encountered a fatal error, and will now terminate. Mid 2011 iMac - High Sierra I recently updated my 27in Mid 2011 iMac to a 1Tb SSD HD and to High Sierra. Now I don't have access to my Google drive :(

I've been looking everywhere and have found no solution to this. Can anyone help?

More details from the error:

"An uncaught exception was raised during execution of the main script.

This may mean that an unexpected error has occurred, or that you do not have all of the dependencies for this application.

See the Console for a detailed traceback."

Two errors I can see in the Console:

[ERROR] - Unknown CGXDisplayDevice: 0x41dc9d00

volume validation failed for &lt;&lt;(null)>>

Any ideas?
Had the same problem, now solved. ~/Library/Application Support/Google belongs to root. Either change privileges:

sudo chmod a+wx ~/Library/"Application Support"/Google


Or change owner:

sudo chown NameOfMyAccount ~/Library/"Application Support"/Google
