Mouse is stuck on a late 2015 27" iMac!
Rest the PRAM, still stuck.
System is active, can access screen and navigate with keyboard.
Anyone know what to attempt next other than buying a PC?
Macs are very frustrating when having issues.
Apple help is like buying Powerball tickets.
iMac (Retina 5K, 27-inch, Late 2015), OS X El Capitan (10.11.3)
