How To Fix Google Drive Not Syncing On Mac

Thе Backup and Sync app from Google works just fine to let you sync your local content with your Google Drive account. Occasionally, you might come across errors with this sync process. When the sync issues occur, you can’t sync any of the files from your Mac to your Google Drive account.

There are a few things you can do when Google Drive is not syncing on your Mac. These methods include restarting the sync process, disabling the proxy server, and so on.

1. Click on the app icon, choose the three dots, and select Resume to continue the sync process.

1. Launch Backup and Sync when your Mac boots-up and let it sync your files.

Turn Off The Firewall On Your Mac

1. Select Security & Privacy on the following screen.

Here’s how you ensure it.

1. Click on the app icon at the top, choose the three-dots, and select Preferences.

1. Click on My MacBook Pro in the left sidebar. The app might show a different device name depending on what you’re using.

1. If the folder isn’t listed, click on Choose Folder to add it to the sync list.

Ensure The App Opens At Login For Automatic Sync

If Backup and Sync doesn’t sync your files automatically, it may be you haven’t set it to automatically launch at boot-up. You can fix it by adding the app to your startup items list.

1. Click on the Apple logo at the top-left corner of your screen and select System Preferences.

1. Click on Users & Groups on the following screen.

1. Click on the Login Items tab on the right-hand side pane.

1. Ensure there’s an entry named Backup and sync from Google in the list.

1. If there isn’t, click on the + (plus) sign, navigate to your Applications folder, and choose Backup and Sync to be added to the list.

Run The Script Bundled With “Backup and Sync”

1. Open the Contents folder.

1. Open the MacOS folder.

Proxy connections may sometimes interrupt your sync process. Therefore, keep your proxies disabled while you use the Backup and Sync app to sync your files with your Google Drive account.
