I have recently purchased two new MacBook Pros. One is a 2016 13" MacBook Pro, the other a 2017 15" MacBook Pro. On both of them, I have had to reinstall macOS High Sierra from the Recovery Tools. On both machines, it has taken over 5 hours to install.
These aren't the low-end Mac Pros, these are the maxed-out config-to-order, with upgraded processors, drives, and RAM. So it is unfathomable that it would take so long to install macOS High Sierra.
I am currently waiting for the 15" MacBook Pro to install High Sierra going on 6 hours now. The progress bar does move, but ever so slightly. The "time remaining" is always 1 hour +/- 30 or so minutes, but obviously that isn't accurate.
Since posting this question, macOS is still sitting at 52 minutes remaining for the last hour. The progress bar has not moved a pixel.
It is normal for macOS High Sierra to install this slowly on these machines? If not, what can I do to reinstall the software more quickly?
