I am trying to download and install the High Sierra Public Beta. My Mac is running 10.12.5.
I'm registered in the Public Beta Test program. I have downloaded the app Install macOS High Sierra Beta. When I run the app (from within App Store) it does some work then responds with a notification:
"Installation requires downloading important content. That content can't be downloaded at this time. Try again later."
Has anyone else had this ? Is there a problem with the 10.13 downloads ?
Thanks.
Garry.
