I just got a logitech M510 wireless mouse that I am using with my 2012 MacBook Pro. The problem is every time I put the computer to sleep, the mouse doesn't work when I turn it back on. Toggling the power switch on the bottom of the mouse won't fix it... I have to unplug and replug the unifying receiver to get it working again. Anyone else have this problem? Is there any way to fix it? I have a different model logitech wireless mouse that works fine with an old windows machine (even after sleeping). Hoping I can make the mac do the same. Thanks.
