13 Feb Solved: FortiClient VPN permission error on MacOS

Using FortiClient VPN on macOS can sometimes be tricky. One common problem is the pesky permission error. If you’ve run into this issue, don’t worry! We’ve got a simple fix for you.

Understanding the Problem

FortiClient VPN needs specific permissions to work properly. MacOS often blocks these for security reasons. The result? You get an error when trying to connect.

This usually happens after a new installation or an update.

Step-by-Step Solution

Follow these steps to resolve the issue:

1. Check System Preferences

• Click the Apple menu () and go to System Settings (or System Preferences on older macOS versions).
• Navigate to Privacy & Security.
• Scroll down to Full Disk Access.
• Find FortiClient. If it’s not listed, click the + button and add it.
• Enable the checkbox for FortiClient.

2. Allow System Extensions

• In Privacy & Security, look for a message stating that a system extension has been blocked.
• If you see this message, click Allow.
• Restart your Mac.

3. Grant Network Permissions

Sometimes FortiClient needs explicit network permissions.

• Go to System Settings > Network.
• Ensure FortiClient VPN has the necessary access.
• Click Apply if you’ve made any changes.

4. Reinstall FortiClient (If Needed)

If the issue persists, a fresh installation might help.

• Uninstall FortiClient using the official uninstall tool (found in the installation folder).
• Restart your Mac.
• Download the latest version of FortiClient from the official site.
• Reinstall and follow the above steps.

Why Does This Error Happen?

MacOS prioritizes security. It often prevents apps from accessing sensitive data and network functions. FortiClient requires special permissions, which aren’t automatically granted during installation.

That’s why manual configuration is needed.

Additional Tips

• Keep macOS and FortiClient updated.
• Check your firewall settings. Some firewalls may block VPN traffic.
• If using an M1 or M2 Mac, ensure Rosetta is installed.

Still having issues? Try contacting your IT administrator. Sometimes, company policies affect VPN configurations.

Conclusion

Fixing the FortiClient VPN permission error on macOS is straightforward. A few security settings adjustments can get you back online. Follow this guide carefully, and you’ll be connected in no time!
