Greetings! I have a nice Microsoft Bluetooth mouse 5000 that has a side button. OSX doesnt see it at all. Back when i was using my old Macbook 3,1 in 2012 with Lion i had intellipoint? i think it was called and the driver worked. But in Sierra on my MBP 9,1 i cant seem to find a suitable driver to say enable expose or spaces with this button. As well as to be able to separately scroll the proper way on a mouse unlike the natural way on the trackpad? Any suggestions?
