I had absolutely no problems in setting up the SlimBlade BT mouse for use with my MacBook. Press the power button that is hidden under the slidable trim and look for the green power indicator on the opposite side to glow solid green for three seconds, then depress the mode switch that is located at the scroll wheel for three seconds and you’re ready to go for regular use as a mouse. The SlimBlade is a full featured laser mouse that just performs two functions, both very well.
