I have copied the title from this thread, because my case is very similar, but not quite the same with respect to one detail. Basically, I got a second-hand Mac Pro that was all set up by the previous owner. But I wanted to just erase and set it up anew, because of privacy concerns. Unfortunately, I did wipe the disk first from the recovery menu (Holding Cmd + R on bootup). So I cannot boot to the previous OS either. I used to have El Capitan on it.
The issue is I get the same message "This item is temporarily unavailable", because I have never owned a Mac so have no account linked to macOS. After much research, I thought logging in to iCloud from Safari would help, but it just gives me a white screen as mentioned in the linked question. So now I am considering 2 options:
- Can I get a friend who does have a new Mac with a new version of the macOS (not El Capitan) to log in and then, once installed, remove him and login from my non-macOS-linked account?
- There are quite lengthy steps to get a bootable USB with El Capitan from a Windows computer in this question. I don't mind following them, IF they work. Will this work or just give me the same problem because my account isn't linked to any macOS?
