Tried running your script from JSS and it just stalls out.

@LovelessinSEA It works for me. Can you send me the log?

@anverhousseini What log are you looking for? The install doesn't get past this point, it just sits here for as long as i would let it. Since the policy is pending it never gives a failure log in JSS.

@LovelessinSEA I can't help you if I don't see the logs. Can you run the script outside of JSS?

@anverhousseini apologies for not responding earlier, your script is perfect, I had some bogus code left over from testing that was causing an issue. Thanks for your help! only thing i would mention is it would be nice to open the application after the install.
so i added

open -a /Applications/Backup and Sync.app

to the script.

Thanks again!!

@LovelessinSEA
Do you know of a way to modify this script. To point to a local shared drive on the network to pull from instead of downloading backup & sync to each device I push the script to?

I'd love to find a way to further automate this using our single sign on so it can auto login to backup and sync.

Just tested this script against 10.14.3 on a new MacBook Air and it still works as advertised. Thanks!

Does this script manage any updates to Backup & Sync? A laptop displayed the message to install the upgraded version of Backup & Sync, so wondering the best method to manage this.

Does this still work since the app name is now Backup and Sync from Google.app ?

Does anyone have the updated script for "Drive for Desktop"?
