Hello, I'm on a rMbp 16GB Ram I7, I'm honestly tired of seeing the Sierra upgrade window whenever I'm in the app store..and new is new I guess. Has anyone run into any problems with Sierra, running a similar setup as me? Any slowdowns or sluggish behavior? Battery life? WIFI/NEtwork Problems? Does it use more memory than El Cap? Thanks for your help and my apologies if this has been covered before.
