Question: Problems with High Sierra download and install

I finally got around to downloading and installing the new update but the install has failed or stalled. It’s been completing the install for about the last 5 hours, I’ve tried rebooting a few times and I’m worried I’ve lost everything. I couldn’t get an appointment to take it into the store because well I can’t wait 2 weeks for a slot. Is anyone else having this problem?
