Chosen Solution

press and Hold Shift + Control + Option and Power button for 12 seconds.

Release all keys at the same time, then reconnect the Power cable and turn the Mac back on again.

Now, reboot the Mac again and this time hold down Command+Option+P+R keys concurrently for about 20 seconds, this resets the NVRAM and restart Mac
