Kensington TrackballWorks

Kensington TrackballWorks has been discontinued by Kensington and is no longer actively maintained. The preference pane will continue to work under Rosetta 2 today, but Apple is removing Rosetta 2 in macOS 28 (September 2028), at which point this preference pane will stop loading in System Settings if it remains Intel-only. Check Kensington's support site to see if a native Apple Silicon version of the TrackballWorks preference pane was released before discontinuation. If Kensington has not shipped a native build, you will need to either use your trackball's basic macOS-native pointer settings (available directly in System Settings > Trackpad, which work with most Kensington trackballs) or contact Kensington support to ask whether they plan to release a native build before Rosetta 2 is removed. Some Kensington trackballs function adequately with only the default macOS settings, so test whether your device works acceptably without the custom preference pane before the September 2028 deadline.
