There was no way to 'wake it up' from the keyboard or the mouse. Reviewed in the United States on October 21, 2013. I have tried USB keyboards designed for the pc with little or no effect.
The keys feel a little more 'loose' and lighter than some keyboards, and I was afraid that that would make the keys either not responsive or cause double-touch issues or something. after the bluetooth keyboard is set up on mac, click on quit button to close bluetooth setup assistant, the btkey is ready to use.
