Known Issue: VPN not working after upgrade to macOS 11.x (Big Sur)

Tags vpn mac

After upgrading macOS to version 11.x (Big Sur) the GlobalProtect VPN software will not connect. This happens because GlobalProtect versions less than 5.1.4 do not support macOS Big Sur. 

You should upgrade your GlobalProtect software to version 5.1.4 or higher. You can install the newer version over top of the existing GlobalProtect client. You can get a new version of the GlobalProtect client that supports Big Sur from this article (login required). Download the file and launch it.

You can review the Related Articles session for instructions on how to install GlobalProtect (skip the download steps 1 and 2).

After the upgrade, when you connect you may receive a message regarding a different version of GlobalProtect.  The message may state that there is an older version available and asks if you would they like to install it. Click NO to this prompt if it is for an older version.
