Where is the Original High Sierra 10.13.1? It says I need to down load it first before I can download the latest version which is 10.13.6.
iMac, macOS 10.12
You must have the 10.13 Combo Updater, you need the full installer, which is 10.13.6...
Don't use FireFox or Waterfox for this link…

If you get a corrupted message...
Naw, not damaged, it's just that you have an old copy already in Applications, there are 2 cures...
Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS High Sierra App in Applications, so expired Certificates are not expired.
Or... trash the Install MacsOS High Sierra.app in Applications, empty trash & restart, then a new copy of a more recent version can be downloaded…
