Right button won't click on Apple Magic Mouse 2
I was having trouble with the right-click on my Magic Mouse 2 but couldn't find much in the Apple Community or anywhere really. I did watch one YouTuber pry his open with a screwdriver... don't do that! He fixed his clicking problem, but he had dropped it, so that maybe forced his hand.
Upon closer inspection of my mouse, I saw there was a bunch of junk in the space between the top and bottom parts of the mouse, so I took a toothpick and dug out a pretty sizable amount of lint. Works like a champ now.
Try that first before you go all Terminator on your sleek, delicate, little mouse.
