Hi Cheryl,
I also had a failed High Sierra install last night. The update seemed to
download and install, but wouldn’t reboot. I used Be My Eyes to get a sighted
person to tell me what was on the screen, and there was some sort of message
about the computer encountered a problem and needed to restart. It wouldn’t
restart though. Just a spinning Apple symbol or something. Tonight I had a
sighted friend help me boot to a network enabled recovery by pressing command +
Option + R while turning on the power. For some reason I wasn’t able to get
Voiceover feedback on this screen, but once my friend chose my WIFI network, I
was able to turn on VO and then erase my hard drive and re-install High Sierra.
When setting up High Sierra, I chose to migrate files from a Time Machine
backup. I thought all my programs would be re-installed, but no luck. Not all
my documents were recovered either. Nothing crucial lost, thankfully! I am
running a brand new iMac 2017 with a 512 GB SSD drive, a 3.6 Ghz processor, and
16 GB of RAM. I’ve never had an install fail on my old iMac Early 2009, so
didn’t even worry when beginning the install. Lesson learned! :)
Having said all that, High Sierra seems really fast and responsive.
Cheers,
Russell

I don't want to start a panic or make people afraid to upgrade to High Sierra
but I just had a failed attempt last night. All I know at this point is that
I clicked the install button and the restart button - and sat and sat and
sat. I tried doing vo-f5 thinking that I would hear voiceover since my
computer was still running but there was no voice. I sat there waiting for
some time and even tried toggling voiceover on and off several times. I even
just about fell asleep waiting, probably did doze. Finally I had no choice
but to force the computer to turn off and then turn it on again. Nothing came
up, which is probably understandable. I put in my backup disk and booted into
that and found that my other drive still mounted and had a Users folder and
other folders that showed the installation must have been at least begun but
no system at all was now installed. It is important to note that I was
installing on an external drive because my hard drive has been dead for some
time but in all the installs I have done this has not been an issue. Anyway I
am now using superduper to copy my backup drive to the drive on which I
attempted to install, having erased it completely. I am sure eventually I
will try the upgrade again but it will probably be a while. I know this can
happen at any time but because this upgrade wasn't billed as being such a
major new release I somehow wasn't expecting a problem. Again, I have done
many, many installs - on my own and on other people's computers - without a
problem but I thought I should report this as a reminder that caution and
proper preparation of backup options is always essential.
