Extra Keys is an app which allows the use of the Logitech G13 Advanced Gameboard on macOS, particularly macOS 10.15 (Catalina) and later, where the manufacturer's software ended, but also on macOS 10.14 (Mojave) if preferred.
The G13 Advanced Gameboard is a USB keypad which has been popular with gamers as well as non-gamers to increase their capabilities and efficiency controlling games, development tools, and other apps. Since manufacturer support for this hardware was dropped with the release of macOS Catalina, Extra Keys fills the void allowing owners to keep using their gameboard.
