Late-2011 MacBook Pro here but similar vintage. Had in-place upgrades or Migration Assistant moves going all the way back to my eMac G4 on Jaguar (OSX 10.2). Really must try one of these wipe-and-reinstall things one of these years.

same, same though a clamshell Macbook. Just amazing. and to be honest I think Jaguar was an upgrade on MacOS9.

Can I just do a Option-Command-R to do a clean install from the internet? Has the online install from Apple been updated yet?

I just downloaded High Sierra from the App Store and kicked off the install process. I am now on the black screen where it says “installation in progress - calculating time remaining “. It’s been on that with no progress for hours now. Anyone know what I should do??

Some folks have had success forcing the computer to shutdown, then restarting.
 
Created a APFS partition on my MBP HDD and cloned over a copy of HS HFS+ to the APFS using CCC.
First boot was looooong but 2nd boot was about the same speed so no improvement on boot times even with APFS with a physical HDD.
I'll wait for the next update and see and compare HFS vs APFS boot times.
Once either boots they seem workable as a normal MacOS for general use.

Macbook Air Mid 2012 i7 / 8GB, if anyone has one or something close and upgrades pls let us know how it is and good luck!!
I have that model and it was successful but I have copies of Sierra just in case I need to fall back. Only app that was trouble was my Photoshop CS3. Has trouble using FILE:OPEN dialog. Could be a java problem since it had to be reinstalled.
I also am fiddling around with a clean install of HS on the HDD and APFS to see if any faster.
It might be good to test after you have an image copy using CCC or other duplicator. That way you don't have to do a clean install and reinstall.
[doublepost=1506918712][/doublepost]After booting from various clean installs and updated to latest OS X and MacOS on my MBP mid 2012 with HDD this is what I found:
10.7, 10.8, 10.9, 10.10 all 50-60 seconds
10.11, 10.12, 10.13 all 83-93 seconds
High Sierra APFS HDD 83 seconds.
10.12 HFS+ = 10.13 APFS boot times
So there's lots of room for improvement for physical HDD. Should boot below 60 seconds if they want to impress.
 
After installing macOS High Sierra today, I get graphics glitches on my MacBook Pro 2015 15" internal screen when logging out. Anyone has this issue or other graphics glitches issues?

On my MacPro, after it wakes up the icons on the menu bar (top of screen) and the menu bar itself are dark. They stay dark until i click on one of them then menu bar goes back to normal and and the icons look normal. On my rMBP 13", I have had one event where the computer shutdown but the screen never shut off, that is the screen was on but dark. A restart fixed that, so far.
