I am currently running MacOS Sierra 10.12.1. I have a magic mouse 2, magic trackpad, Wacom tablet, and a spare magic mouse. Suddenly while working my mouse cursor became stuck in the menu bar above my username. I could shake the cursor with the mouse to enlarge the pointer, but I couldn’t seem to move it.
- Turned off my Bose QC 35s
- Turned off my magic trackpad
- Tried my extra magic mouse
- Tabbed with my magic keyboard to BT in the menu bar to check battery levels
Still, the mouse cursor was stuck in place. 30 minutes later I see that my Wacom tablet stylus has rolled onto the tablet and was intercepting all mouse input with the stylus. Flipped it off and I could use my mouse again.
