Hello bbsoc, For automatic global-protect logins, firstly we need to make sure that the connection method is Single-Sign-On (SSO). As far as the error 'Detected another instance (An old Global Protect instance exists, new instance cannot be started!)' is concerned, can we try to uninstall the entire GP package from MAC and re-install it? Here is a document that will help you in doing the same: How to Uninstall GlobalProtect Client Mac OS X FYI, there was an old known issue where the same error was seen while running GP client 1.1.4 on MAC. Although, it was fixed in 1.1.6 version. I am sure you would be using the latest version : GP-1.2.8 Let me know if that works! Thanks and regards, Kunal Adak
