Answer 1

I have had the same issue and searched the forums and found nothing that helped. I contacted apple support and this is what they told me to do:
First we’ll do the SMC reset
1.) Shut down the Mac and connect to power source.
2.) Unplug external devices, flash drives, external monitors, external HD (Keep the Mac plugged into power source)
3.) Hold down “Shift” + “Control” + “Option” (On the left side of the keyboard) + Power key for 30 seconds.
*The Mac should remain powered off during the reset, the LED on the MagSafe Adapter may change colors.
**The “Option” key is also known as the “Alt” key on some Macs.
Awesome, now let’s reset the NVRAM
1.) Locate these keys “Command”, “Option, “P” & “R”
2.) Power on your Mac
3.) Immediately press and hold all 4 keys “Command” “Option” “P” “R”
4.) Listen for 2 boot chimes and then release.
**The “Option” key is also known as the “Alt” key on some Macs.
