How to verify that Google Drive for Desktop is working (Macbook)
First thing to check is the color of the Google Drive for Desktop icon on the top of your screen.
It should always look like this - dark:
and not like this - light/gray: 
If it's light, it's not actively backing up your Macbook. If it's light/gray click on the Google Drive icon, then the gear, and tap on quit. Then find the app (Google Drive) in your Application folder and launch again.
Tap on the Google Drive for Desktop icon > gear symbol > Preferences > You should see two folders being backed up - Desktop and Documents


If no folders are listed that means your Macbook is not currently being backed up!
