Clean Install of High Sierra: Multiple Fails, Pls Advise
I'm trying to clean install High Sierra on a Mac Pro 5,1 (mid-2010, 6-core). High Sierra has been on this machine for two years.
Many attempts have failed, the last three failed with the message: "The recovery server could not be contacted". That's a new one.
Quick details:
1. I want to install High Sierra to an NVMe 480GB SSD. Two early attempts failed (they stopped at a window with a stuck progress bar)
2. Several more attempts installing High Sierra to the system drive also got stuck.
Then tonight I read I should try the file “Install 10.13.6 macOS HIGH SIERRA”. So I downloaded it, recreated a USB boot installer with that installer and then got the error "The recovery server could not be contacted" again.
3. Even an attempt to simply reinstate High Sierra from a Time Machine backup failed. My old school Time Capsule died last year, so backups from multiple Macs are all on a USB3 portable HD.
I followed prep directions from an Apple Support page to the letter.
Is there a way of doing a clean install via Terminal?
Thank you in advance!
Mac Pro, macOS 10.13
