I'm trying to reinstall macOS Sierra from the recovery partition, and I'm getting an error when it is checking for eligibility This computer is a mac

The computer that I'm using is most definitely a Mac, and I can't use it until I install Sierra


I just set the date in terminal using the date command, and it is now letting me install macOS Sierra

  • Unclear. You just set the date in terminal...and what happened? – David Nov 15 '18 at 16:22

  • Which is all good and stuff, but my external hdd connected isn't being recognized so I can't restore from backup – Sam Nov 15 '18 at 16:48

    I set the current date and it worked. Tried with dates which should correlate better to the release of the Sierra version in September of 2016 but that did not go through at all. – Gesias Nov 27 '18 at 10:23
