MacBook Pro (Retina, 15-inch, Mid 2014)
In recent days the mouse pointer will be inoperable after waking from sleep. If I cmd tab I can find the pointer, but it will not respond to trackpad movement or clicks. It does not recover if I close applications, open the force quit window or resleep. Only a reboot will bring it back.
Just now it froze as I was typing. Additionally, the character I was typing repeated, as if I was holding my finger on the key combination (it was the '$' character). Again, only a reboot would stop it.
SMC reset did not fix it.
How can I resolve this so that it does not happen again?
