I've followed practically all the tutorials on cracking hashes for a macOS password, but I've come up empty handed.

I've ultimately come up with this hash:


I have tried both hashcat -m 7100 and john the ripper, but still nothing.

Any help would be immensely appreciated. I am trying to crack a Yosemite password.

  • @Deesbek any further help or tips on the hash? – bigman Oct 18 at 14:52

You may find that just like with most unix like systems OS X uses a salt and a hash.

I would review some of the answers on AskDifferent such as:

What type of hash are a Mac's password stored in?

Your password and the salt is grilled by sha512 many times, then the result is base64'ed and reverse xxd'ed. Together with the salt and the iterations it's xxd'ed and base64'ed again.

  • so yes, i did follow that tutorial today and on the second to last step it says how to put together the hash for hash cat, which is the one I've included in my original post. so it's $ml$<iterations(integer)>$<salt(hex)>$<entropy(hex)> – bigman Oct 18 at 0:31
  • well if they are using sha512, then I don't think it can be cracked – scipsycho Oct 18 at 13:59
  • @scipsycho well i mean in the tutorial that Deesbek linked, the poster said it worked just fine.... – bigman Oct 18 at 14:53
