For example my wireless keyboard and mouse use one receiver that is plugged into one usb slot, whereas my previous ones each came with a receiver. One for my mouse and another for my keyboard. It took up two usb slots. MX Keys unable to pair via Bluetooth on MacOS Mojave. Keyboard appears to be charged and in pairing mode; Mac quickly finds the device and attempts to connect. However, I am unable to input the pairing code as none of the keys actually work. The backlight just slowly blinks. Any ideas? 3- find your keyboard name from the list of Bluetooth devices and click connect The first step in fixing the issue is to rule out hardware problems. The best way to do this is to connect the same keyboard to another computer or laptop. If the issue occurs on the other system as well, then your keyboard is to blame.
