Google Drive Not Syncing: 12 Fixes for Windows and Mac (2026)

Google Drive sync issues are one of the most disruptive cloud storage problems — especially when you're mid-project and a file you edited on one device simply isn't showing up on another. The causes range from a full storage quota to a stuck proxy setting, and the fix is rarely obvious from the error state alone.

This guide covers 12 tested solutions to fix Google Drive not syncing on Windows and Mac, ordered from the quickest checks to the more involved resets. If you've already tried the standard fixes without success, Part 3 covers UPDF Cloud as a reliable sync alternative specifically for PDF documents — no syncing errors, no storage quota headaches.

Part 1: Why Is Google Drive Not Syncing? Common Causes

Google Drive sync failures typically trace back to one of these root causes:

• Weak or unstable internet connection — sync requires a stable connection; packet loss or VPN interference can silently stall uploads.
• Google server outage or maintenance — if Google's servers are down, no client-side fix will help until the service recovers.
• Full storage quota — once your Google account storage (shared across Drive, Gmail, and Photos) hits its limit, new files stop syncing.
• Insufficient local disk space — if your computer's drive is full, Google Drive for Desktop cannot write synced files to it.
• Incorrect proxy or firewall settings — corporate or VPN proxy configurations can block Google Drive's sync processes.
• Outdated Google Drive for Desktop app — older versions may fail to authenticate or communicate properly with current Google servers.
• File conflicts or unsupported file types — certain file names (with special characters) or file sizes exceeding Google's limits can cause sync to stall on specific items.
• Account authentication issues — an expired session or account disconnection silently stops sync without a clear error message.

Part 2: 12 Fixes for Google Drive Not Syncing on Windows and Mac

The solutions below are ordered from quickest to most involved. Work through them in sequence — most sync issues resolve within the first four or five fixes.

Solution 1. Check the Server

Before trying any other fix, check whether Google Drive's servers are experiencing an outage. Visit the Google Workspace Status Dashboard to see real-time status for all Google services. If Google Drive is listed as "Service Disruption" or "Outage," the issue is on Google's end — wait for it to resolve before troubleshooting further. If all services show green, move to the next solution.

Solution 2: Check the Internet Connection

A dropped or throttled connection is one of the most common causes of sync stalls. Try the following in order:

• Open a browser and load a page you haven't visited before to confirm connectivity.
• If the page loads slowly or not at all, restart your router or modem (unplug for 30 seconds, then reconnect).
• If you are connected via VPN, try temporarily disabling it — some VPN configurations block Google's sync servers.
• Switch from Wi-Fi to a wired Ethernet connection if available; unstable Wi-Fi can cause partial sync failures that are hard to diagnose.

Solution 3: Pause and Resume Syncing

If sync has stalled on a specific file, a pause-and-resume cycle forces Google Drive for Desktop to re-evaluate all pending items and retry any stuck transfers.

Step 1: Click the Google Drive icon from the Taskbar on Windows (On Mac, it appears in the menu bar) and tap the "Gear" icon.

Step 2: Select "Pause Syncing" to pause the syncing, and after a few moments (wait 15–20 seconds), choose "Resume Syncing." Watch whether the sync status indicator starts moving.

Solution 4: Restart Google Drive

You may need to restart the Google Drive app on your system if Google Drive is not syncing is still unresolved. Restarting it will force Google Drive to look for un-synced files and synchronize them. Use these steps to restart Google Drive:

Step 1: On Windows: right-click the taskbar → Task Manager → find Google Drive in the list of processes → click End Task.

On Mac: open Activity Monitor (Spotlight → type "Activity Monitor") → find "Google Drive" → click the Force Quit (✕) button.

Step 2: Relaunch Google Drive from the Start menu (Windows) or Applications folder (Mac). Wait about 60 seconds for the initial sync check to complete.

Solution 5: Run Google Drive as Administrator

This fix applies to Windows only. If Google Drive lacks permission to write files to a protected folder (such as a folder in Program Files or a network-mapped drive), syncing will silently fail for those specific locations. Running Google Drive as Administrator grants it elevated access.

Step 1: Search for Google Drive in the Windows search bar and once it appears, select "Run as administrator." It will launch Google Drive with administrator privileges. Confirm any UAC (User Account Control) prompt that appears.

Step 2: Check whether the previously stuck files now begin syncing.

Solution 6: Reconnect Your Google Account

It is also possible that the problem behind the Google Drive files not showing up issue lies with your Google Account. Thus, you should try disconnecting and reconnecting the Google Account from the Google Drive app. Follow these steps to disconnect and reconnect your Google Account:

Step 1: Click the Google Drive icon in the system tray and tap the "Gear" icon. Here, press "Preferences," and on the next screen, click the gear icon again inside Preferences to open "Settings".

Step 2: Click "Disconnect Account" and confirm your action through "Disconnect."

Step 3: Relaunch Google Drive from the "Start" menu (Windows) or "Applications" folder (Mac) → click "Sign in with browser" → complete the sign-in process in the browser that opens. Google Drive will re-authenticate and restart syncing.

Solution 7: Change Google Drive Proxy Settings

Sometimes, the issue behind Google Drive not syncing can relate to the proxy settings of Google Drive. Changing the proxy setting should resolve the problem if that is the case. Use the following steps to change Google Drive proxy settings:

Step 1: Open Google Drive Preferences (gear icon in system tray → Preferences → gear icon inside → Settings).

Step 2: Scroll down to find "Proxy Settings." Now change the "Proxy Settings" from "Auto-detect" to "Direct Connection" and check if the issue is resolved.

Step 3: Click Done and allow Google Drive to restart. If sync resumes, the proxy configuration was the culprit. If not, you can revert this setting and try the next solution.

Solution 8: Check That All Folders Are Enabled for Sync

Not selecting all folders when giving your computer access to Google Drive can also cause the Google Drive folder not to sync issue. To remedy this problem, you will need to change settings in the "Folders from Drive" part with these steps:

Step 1: Start by clicking the Google Drive icon on the Taskbar and tapping the "Gear" icon to access "Preferences." Here, select "Google Drive" from the left side.

Step 2: Under sync mode, you have two options:

• Mirror Files — all files are stored both on your local disk and in the cloud. Switch to this mode if you need all files to be consistently available offline and sync reliably.
• Stream Files — files are stored in the cloud and downloaded on-demand; if your connection is poor, some files may not sync immediately.

Step 3: If you switch modes, Google Drive will restart and re-sync. This may take some time depending on your total file count.

Solution 9: Restart Your Computer

Temporary system bugs and glitches in your computer or Mac can also prevent the Google Drive sync process. In such situations, it is better to restart your device to flush out all temporary system bugs and reset all processes. Given below are the steps for rebooting your system:

Windows: Click the "Start" menu to access the "Power" menu and tap "Restart."

Mac: Click the "Apple" logo from the top left corner and select "Restart" to reboot the device.

Solution 10: Free Up or Expand Google Drive Storage

If syncing has stopped for new or modified files, a full storage quota is a common culprit. Google account storage (15 GB free) is shared across Google Drive, Gmail, and Google Photos.

Check your current usage: Open drive.google.com → scroll to the bottom-left to see your storage usage bar.

To free up space without paying:

• In Google Drive, sort files by size (Storage → Large files) and delete what you no longer need.
• Empty the Google Drive trash: click Trash in the left sidebar → Empty Trash.
• In Gmail, delete large attachments and empty Gmail's trash.
• In Google Photos, remove high-resolution photos or videos you have backed up elsewhere.

To expand your storage:

Open drive.google.com → scroll to the bottom-left and click "Get more storage", choose a Google One plan starting from 100 GB. Plans are available monthly or annually.

Solution 11: Reinstall Google Drive

Finally, if no solution has worked so far, it is best to remove and reinstall Google Drive on your computer to resolve the Google Drive desktop not syncing issue. Reinstalling Google Drive will help remove all the system issues that were preventing the sync. Here is the guide to uninstall and reinstall Google Drive on your PC:

Windows:

Step 1: Press Win + R → type "appwiz.cpl" → press Enter to open Programs & Features. Find Google Drive → click Uninstall → follow the prompts.

Step 2: Restart your computer after uninstallation.

Step 3: Download the latest version of Google Drive for Desktop from https://workspace.google.com/products/drive/#download. Install and sign in — sync will resume automatically.

Mac:

Step 1: Open Finder → Applications → drag Google Drive to the Trash → Empty the trash.

Step 2: Restart your Mac.

Step 3: Download and install the latest version from https://workspace.google.com/products/drive/#download. Sign in to complete the reinstall.

Solution 12. Update Google Drive for Desktop to the Latest Version

An outdated client can fail to authenticate with Google's servers or encounter API compatibility issues that silently break sync. Google periodically updates the authentication protocols for Google Drive for Desktop — running an outdated version can cause sync to stop without any clear error.

Check and update on Windows or Mac:

• Click the Google Drive icon in the system tray (Windows) or menu bar (Mac).
• Click the gear icon → About Google Drive.
• If an update is available, you will see a prompt to install it. Click to update and restart the app.

If no update prompt appears, your app is current. Compare the version shown with the latest release listed at support.google.com/drive/answer/10838124 to confirm.
