I have been using MaxMenus with every OS release since 10.5. It worked well in Sierra and continues to work now in Mojave. But my old serial number does not work. While the program still functions, I have to work around some issues that do not fully function because it will not accept my serial number. Of course the developer can no longer be contacted. I would gladly pay a fee for a working serial number. And I am glad to offer for free my working serial number which worked well through 10.12. Does anyone have a MaxMenus serial number that Mojave will accept?
