KVM Switch?
I want to use a KVM switch to share my mouse, and keyboard with my 2015 MBP and my 2011 iMac. IIRC, since the former has USB 3 ports while the latter has USB 2 ports, I was wondering if KVM switches are USB speed agnostic or if their ports have a particular USB speed (though for KB/mouse speed should not be a factor)? Also, I was wondering if there is a particular brand of KVM switch that is more "Mac-friendly" than the others.
