Re: macbook 13inch retina a1502
Sorry i didn't see you already did upload ...ok here are the steps now password is gone no need to do anything else with your file just reflash it and follow my steps after you do so or the cloud will reset it again once you go online.
steps:Make sure to do this steps after reflash:
Resetting NVRAM
i) Shut down your Apple Mac.
ii) Locate the following keys on the keyboard: Command, Option, P, and R.
iii) Turn on your Mac.
iv) Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
v) Hold these keys until the computer restarts and you hear the startup sound for a second time.
vi) Release the keys.
And after that... reinstall the OS is a must to have no other problems.
