We’ve just released a little update to Jamf Switcher, bringing the app to 1.1
This update strips /?failover from a JPS URL when writing to the com.jamfsoftware.jss.plist for the Jamf Applications, but keeps /?failover when opening Safari.
1.1 is available now, & Jamf Switcher should prompt for the update when launched or can be installed via the “Check for updates” menu from within Jamf Switcher itself or manually downloaded from here.
