How to Fix Problems Uploading Large Files

If you are trying to upload a file of 3-5 GB to Drive for Mac and see an error message or a Waiting to Start message that doesn't disappear, you may be able to resolve the problem by granting Drive full disk access.

To enable full disk access:

1. Go to System Preferences > Security and Privacy.
2. Click the Privacy tab.
3. Click Full Disk Access in the left panel.
4. If the CloudDrive application does not appear in the window, click the +, and add it.
   
   Drive now has full disk access.
