I have reset and erased all my data from my MacBook ready to pass it on, but Mac OS Sierra will not download onto the Macintosh hd disk. I have used first aid to try and find the problem but first aid is unable to run in this disk. Are there any suggestions that I could try? Thank you
If you are trying to install Sierra from an external source, turn back the clock on the computer to a couple of months after the date on the install.
