Got a doozy on this one... 2016 MBP 15” 6700k 16gb ram Rpro 455 Woke up with what appeared to be a stuck notification. Nothing works left click wise, some stuff will right click but go nowhere. Not even command option escape to relaunch finder works. However, guestures work perfectly. I can’t interact with anything but i can use multi touch guestures to move the UI around. Reboot to safe mode, same thing. Reset SMC and NVRAM. Same thing. Reboot to internet recovery, crash at options screen. Reboot to single user mode, nope. Reboot to target disk mode and get thunderbolt/usb icons. Fantastic, at least I can pull the data off before it goes to the apple store. Use girlfriends 2015, apple thunderbolt 2 cable and apple thunderbolt 2>3 adapter. .... Now hers has the same symptoms. What. The. ****.
