We have a new handy script (install_1013_DP7_17A352a.sh) to install macOS High Sierra Beta DP-7.
The installer.pkg created by the script will simulate the App Store download and installation method, and all you have to do is:
1.) Run install_1013_DP7_17A352a.sh
2.) Run /Applications/Install macOS High Sierra Beta.app
Notes: I have yet to try the scripts myself – I cannot download the files right now (we’re still at sea). Also. You may want to run checkAPFSSettings.sh in single-user mode.
Please note that the App Store.app downloads files to: /Library/Updates but this script will use: /tmp/091-28482 and the downloaded files will be gone after a reboot, so you may want to make a backup of the files!
Note: The preferred way of installing / upgrading High Sierra (DP-7) on a Mac is to use the App Store !!!
