Apple devices have custom support in macOS and they would miss some functionality if taken over by the USB Overdrive. Note that the USB Overdrive does not handle any Apple mouse, trackpad or keyboard. Please read the notes carefully and uninstall any previous version of the USB Overdrive before installing this one.
This is a beta version for Big Sur 11.1 to 11.4. Shameless plug: My famous Contact Tool for iOS is back! USB Overdrive supports macOS Big Sur 11.1 to 11.4.

USB Overdrive 5.0 beta 7 now works in Big Sur 11.4.
