Microsoft Copilot Not Working on Mac? Fixes

If Microsoft Copilot is not working on your Mac, the fix usually involves updating the app, checking your network connection, or clearing the app’s cache. Below are the most common causes and step-by-step solutions to get Copilot running again on macOS.

Why Copilot Fails on macOS

Copilot on Mac is a native app (available via the Mac App Store) that wraps the web-based Copilot experience. Most failures stem from one of a few areas:

• Network issues: Copilot requires a stable internet connection. A weak Wi-Fi signal, VPN, or firewall can block requests.
• Outdated app or macOS: Older versions of the Copilot app or macOS may have compatibility bugs that were later fixed.
• Corrupted cache or local data: Like many apps, Copilot stores temporary files that can become corrupted and cause crashes or blank screens.
• Account or sign-in problems: Copilot requires a Microsoft account (personal or work/school). Token expiration or sign-in conflicts can cause errors.
• Server-side outages: Occasionally, Microsoft’s servers are down, and no client-side fix will help.

Quick Fixes to Try First

Start with these simple steps, as they resolve the majority of issues:

1. Check your internet connection: Open a browser and visit a site like example.com. If it fails, restart your router or switch networks.
2. Restart the Copilot app: Quit Copilot completely (Cmd+Q) and reopen it.
3. Restart your Mac: This clears temporary system glitches.
4. Check Microsoft’s service status: Visit the Microsoft 365 Service Status page (requires sign-in) or search for “Copilot down” to see if others report issues.

Update the Copilot App and macOS

Running outdated software is a common cause. To update the Copilot app:

1. Open the App Store on your Mac.
2. Click your profile icon in the bottom-left corner.
3. Scroll to Updates and find Copilot. Click Update if available.

To update macOS itself, go to System Settings > General > Software Update. Install any pending updates, then restart your Mac. Copilot typically requires a recent macOS version (e.g., macOS 14 Sonoma or later for the native app), so check the App Store listing for minimum requirements.

Clear Copilot’s Cache and Data

If the app opens but shows a blank screen, or responses hang, corrupted cache files are often the culprit. Here’s how to clear them:

1. Quit Copilot (Cmd+Q).
2. Open Finder and press Cmd+Shift+G.
3. Type ~/Library/Containers/com.microsoft.copilot (or search for “Copilot” in the Containers folder) and press Enter.
4. Look for folders named Cache, Caches, or WebKit. Move them to the Trash (do not delete the entire container unless you’re comfortable re-signing in).
5. Restart Copilot. You may need to sign in again.

If you’re not comfortable deleting files manually, you can also uninstall and reinstall the app (see next section).

Reinstall the Copilot App

Reinstalling gives you a clean slate and is the most thorough fix for persistent issues. Here’s how:

1. Quit Copilot.
2. Open Finder > Applications.
3. Drag the Copilot app to the Trash.
4. Empty the Trash.
5. Open the App Store, search for “Microsoft Copilot”, and download it again.
6. Sign in with your Microsoft account and test.

This removes all local data, so you’ll need to re-enter any preferences or customizations.

Sign Out and Back In

Sometimes your authentication token expires or becomes invalid. Signing out and back in refreshes it:

1. Open Copilot.
2. Click your profile icon (usually top-right).
3. Select Sign out.
4. Quit and reopen the app.
5. Sign in again with your Microsoft account.

If you use a work/school account, ensure your organization hasn’t disabled Copilot access. Personal accounts generally work without admin approval.

Use the Web Version as a Workaround

If the native app still fails, you can use Copilot in any browser. Go to copilot.microsoft.com and sign in. This often works when the app has issues, and it’s a good way to determine if the problem is app-specific or account-related. If the web version also fails, the issue is likely on Microsoft’s side or with your network/account.

Common Error Messages and Their Meanings

• “Something went wrong” – Usually a server-side issue or a network timeout. Wait a few minutes and retry.
• “You need to sign in” – Your session expired. Sign out and back in (see above).
• “Copilot is not available in your region” – Copilot is not available in all countries. If you’re traveling, you may need a VPN (though this may violate Microsoft’s terms).
• “Network error” – Your Mac cannot reach Microsoft’s servers. Check firewall settings or try a different network.

Frequently Asked Questions

Why does Copilot keep crashing on my Mac?

Crashing is often due to outdated app versions or macOS incompatibility. Update both, and if that fails, reinstall the app. Also, check that your Mac meets the minimum system requirements (macOS 14 or later for the native app).

Can I use Copilot on an older Mac?

Yes, but only via the web browser. The native app requires a recent macOS version. Older Macs can still access Copilot through Safari, Chrome, or Firefox at copilot.microsoft.com, though performance may be slower.

Is Copilot free on Mac?

Yes, the basic Copilot is free with a Microsoft account. Some advanced features (like longer responses or priority access) may require a Microsoft 365 subscription or Copilot Pro, but the core chat functionality is free.

Why does Copilot say I’m not signed in when I am?

This usually happens when the authentication token expires or the app’s stored credentials are corrupted. Sign out and back in, or clear the app’s cache as described above. If you use multiple Microsoft accounts, ensure you’re signed into the correct one in the app.

Does Copilot work on Apple Silicon (M1/M2/M3) Macs?

Yes, the native Copilot app runs on both Intel and Apple Silicon Macs. If you have an Intel Mac, ensure you’re running the latest macOS version that supports the app.

Can I use Copilot with Siri or Shortcuts on Mac?

Not directly. Copilot is a separate app and does not integrate with Siri or the Shortcuts app. You can, however, use the web version in a browser and create a bookmark for quick access.
