FRESH INSTALL MAC OS SIERRA INSTALL
Erased the MacOS Extended (Journaled) formatted SSD, formatted it in APFS as I thought it was logic to use the format that High Sierra would generate automatically when installing, then same problem: High Sierra on the USB-Drive would not want to install on a APFS formatted drive in Recovery Mode.

But now I don't have macOS to re-create the disk. Had the same problem on old Macbook Air 2011. Now I don't have a working macOS, since I erased the internal SSD, the SSD now seems to have a "installation state", since it can boot to start install, but ends with the above error.Ĭould this be that the USB disk has incomplete files? I feel that the download may still not be complete. I tried twice, with same error, two log files are saved: macOS will offer you startup drive by default so you need to click Show All Disks button and choose your non-startup disk volume. Or maybe you’re looking to install the operating system from scratch. It is the easiest way to install a fresh copy of an operating system. Maybe you’ve got multiple Macs and a limited amount of bandwidth, and don’t want to download the entire operating system for every system.

Change the target drive for installation. The Mac App Store is the default way to upgrade or install macOS, but it doesn’t work for everyone. You will need a way to connect your test disk to a working Mac or Hack like a USB to Sata or if you have a Sata connection available use it. it can be copied using carbon copy cloner or Super Duper, pulled form a working Hackintosh ( intel) or a fresh install. Launch the Installer from the Applications folder and press Continue. First you will need a HDD or SSD with High Sierra installed.
