If you sync certain files, you might need to give macOS permission to access folders and devices. These include:
- Desktop, Documents, and Downloads folders
- Removable and network volumes
- Your Photos library
Drive for desktop requires permission to:
- Access folders or devices you sync with Google Drive or backup to Google Photos
- Use Real-time presence or a Bluetooth key to sign in
If you don't initially grant approval, and later decide to sync a folder or device, go to "System Preferences" and change your privacy settings by following these easy steps.
