On a 2016 MBP I get this error when trying to install Mojave beta 1.
Could it have something to do with having had a Time Machine disk plugged in while trying to update?Are you able to post a photo? I've had that issue in the past if an install was interrupted and there are staging install files in a folder at /macOS\ Installation\ Data. Try rebooting to High Sierra and check root for anomalous files

[doublepost=1528158997][/doublepost]Never mind, that didn’t help. Now how do I check root or what not?
I just checked, and there’s only three terminal scripts in that folder.
Can you take another photo, or tell me what they say?
Looking at your first image it looks like there is a partial High Sierra install on the disk as well as the Mojave install. I'd suggest a visit to the Genius Bar. They don't support beta macOS, but will be able to reinstall High Sierra quickly for you if you don't feel confident doing it yourself. Otherwise you could trying re-installing from recovery (https://support.apple.com/en-us/ht204904).
It shouldn't, but I'm only just installing Mojave myself!
It should be ok. Beta systems aren't designed for your daily driver though, so expect a few reinstalls before Apple releases 10.14 in the fall!Got this sorted out. Reinstalled High Sierra (clean), then installed Mojave over top the clean instal.
One thing that I'm unclear on -- can I restore from a Time Machine backup of my original High Sierra partition, or would that mess things up again?
