I bought a used Mac that only had Windows 7 installed. The seller didn't have the original OS DVD, and the hard drive only had a single NTFS partition. I downloaded Lion from a torrent, burned it to a DVD and attempted to install it. When I create a user, it errors out and continues to ask me to create a user again and again.

How do I get past the user creation step?

  • Which mac do you have? – MrDaniel Sep 26 '12 at 12:01

One solution would be to not download a copy of OS X from a torrent, you never know what you are getting.

  1. Obtain a legal, trusted copy of OS X. If your Mac supports it you can get Mountain Lion for $19.99 USD from the App Store, if not you can order OS X Lion from apple for probably around $29.99.

    • Borrow a friends Mac, visit a Mac at an Apple Store, etc., log in to Mac App Store using your Apple ID.

    • Buy and download OS X.

    • Make a boot-able USB OS X installer

    • Log out of app store

    • Delete the installer you downloaded.

  2. Boot from that copy, by holding down the option key while booting your mac.

  3. Run Disk Utility from the OS X install media, erase the entire hard drive.

  4. Install OS X

  5. Enjoy...
