...and it's been a pain in the butt looking for one. Basically I just want the standard essentials, somewhat ergonomic (no Magic Mouse. I have the Magic Mouse 2 and it strains my hand), has scrolling, back and forth page button THAT WORKS ON OS X, and horizontal scrolling of some sort. It also has to be bluetooth, as my 2016 MBP has no USB ports... Problem is... I've tried 3 different Logitech Bluetooth mouses (MX Master, MX Anywhere2, M720 Triathlon) and they are amazing, for about 3 minutes, then they start connecting and disconnecting and dropping. Eventually just becomes completely incompatible. It works fine with the Unifying receiver, but other than that. It's garbage on Bluetooth. I don't know why. I've attempted to troubleshoot my best. So that being said, what mouses are you guys using that is bluetooth and functional? I have one from Amazon that's been fairly good, but it doesn't have horizontal scrolling.
