My spouse and I both work from home. I have a Macbook Pro that will often times disable the default keyboard and start searching for the wireless keyboard that my spouse uses with his iMac. The mouse does the same thing. The wireless keyboard and mouse are always paired and connected to the iMac. How do I stop my Macbook from continually searching for a third party keyboard. The problem as I see it is when I disconnect from my 27" monitor with, wired USB and keyboard, the computer starts searching for another keyboard instead of just using the default one. How do I change this behavior without completely turning bluetooth off?
