I am trying to upgrade to 11 from version 10.4.1d4. I have paid for it downloaded it repeatedly from the reason website and also downloaded it via BitTorrent but each time I get a message saying that The Unarchiver can't extract the .pkg from the zip file as the archive is incomplete. (see attached image)
I am using the latest version of Unarchiver and running Sierra Mac O/S.
Any ideas of what the problem could be?
thanks
Mathew
