I recently bought Bartender 3 do I need to pay for an upgrade? It has a 4 week trial after this Bartender 4 will be $15, and will have a great discount of 50% for users with a license to any previous version of Bartender. You can use a Bartender 4 license with Bartender 3. Because of the massive changes in macOS Bartender 4 could only be designed to work with the new versions of macOS. Can I use Bartender 4 on macOS Catalina or earlier?īartender 4 is compatible with macOS Big Sur and Monterey.
