I have a late 2012 macbook pro on Yosemite. I was trying to install something, but it said I needed at least 10.11 to install it, so I began to download High Sierra. It's been stuck at "macOS high sierra will be installed on the disk Macintosh HD" for a good while. I kinda need to use the thing I was originally trying to install right away, and this is taking forever. Is this normal? How long does it usually take to install? Is there a way to install El Capitan instead if it'll be faster?
Got a tip for us?

High Sierra download stuck?

Well, now you are committed, I think you cannot really stop this safely.
One of the OSX version upgrades (forgot which one, Sierra?) took sometimes multiple (I mean people reported 16 or more) hours - turns out at that time any unix code (installed by homebrew etc) needed to move and installer was very inefficient as it was moving file by file. This took forever, these unix programs have huge number of small files typically. Not sure if HS still has this issue, but this could be it.
Presumably you have a good bootable backup? In such case you may be able to kill this, boot on that backup and install fresh High Sierra after reformatting the disk. And then do Migration assistant to move back. But I believe that was not faster either.
Not sure if you can get older versions of OSX in App Store, unless you already "own" them, but El Capitan is the last which shows in my App store for download - but I "purchased" it in 2015.

Open up the HighSierra installer log and check what it says at that point. In my case there was an error contacting the server right at the beginning, turned out the internal date had to be set via Terminal first. bsd command looks like this: sudo date 0301100018 (march, 1st, 10am, 2018)
After that the installer went through without any issues.
