Failing this, you may produce a bootable USB installer for Mac-OS Sierra, and boot up out of this by simply holding “Choice” while turning to your own Mac.

You still must wash out the driveway, yet, or your records will stay set up, therefore jump to the ending of this task to achieve that.)

Now proceed up the dial, to deliberately write data on your whole drive. You just have to write past a driveway once to safely wash it. However, if you are paranoid, it is also possible to wash it twice.

This could take a little while. Finally, your Mac will resume and request that you make a merchant account. If you should be donating your Mac off, or purchasing it, then I would advise that you shut down at this time and let those you are donating your Mac to produce their very own account. Afterall, it’s theirs today. Otherwise, love your now-fresh Mac!
