After you update to OS X 10.11 or OS X 10.11.1, devices that use Logitech Control Center (LCC) may experience the following:
-
Cursor movement stops working when an LCC-supported Unifying mouse is connected.
To fix this issue, unplug the receiver and then plug it back in again. -
A Unifying software prompt for multiple receivers appears, even though you only have one Unifying receiver connected.
Reboot your computer to resolve the problem. -
All devices appear twice in the LCC user interface.
Reboot your computer.
