CAUTION! Microsoft natural ergonomic Keyboard 4000 v1 began acting strange on yosemite, and on El Capitan, many [command key + (key)] functions totally AFU.
Support page op sys window only knows about OS X up to 10.7.
Using 27" iMac late 2012 3TB Turbo 3.2 GHz Intel Core i5 24 GB 1600 MHz DDR3.
Apps opening very slow on 10.11.

Serves me right for day one upgrade I guess
