I was a volunteer at a thrift shop several years ago. One day we heard of a bunch of idiots at a party playing with home-made explosives. The radio news item mentioned that a young man from our town had list both legs below the knees and most of the fingers on one hand.
Henceforth the shop was closed on Saturdays as the only volunteers we could get for that day were the unfortunate fellow’s parents. They dropped everything to take care of him.
I vaguely recall seeing somewhere that machine-specific downloads of High Sierra are done. Certainly my attempts to install HS onto the iMac using the installer app from the MacBook Air have failed. Downloading again. Fortunately I have plenty of bandwidth available.
While the iMac lacks an SSD to get full benefit from the High Sierra update, it does have a hardware advantage when it comes to encoding HEVC videos in 10-bit colour.
From Ars Technicha: Only Macs with Skylake and Kaby Lake processors support hardware-accelerated encoding and decoding of HEIF and HEVC files at all; this covers all Macs introduced in 2016 and 2017 and 5K iMacs from late 2015. Only the Kaby Lake processors in 2017's Macs support hardware decoding of HEVC videos with 10-bit colour, one of the few new features that separated Kaby Lake from Skylake in the first place.

// @matigo has been made aware of the issue.
I had to check that my laser printer would still work under High Sierra, it does. There have been driver issues with Fuji/Xerox printers in the past, the Men's Shed iMac was stuck on Yosemite for almost a year before the slack dogs came out with drivers to suit El Capitan.
One nice difference between Sierra & High Sierra is when using Mail in full-screen mode. When you’re using Mail in full-screen mode and go to compose a new message, the compose window automatically pops up beside the main window in Split View mode; in Sierra, the compose window obscures the main window and needs to be minimised and maximised if you want to look at different things, à la iOS.
I had to shut down that YouTube video. Man's a fucken idiot. Pronounces Peugeot as Pee-gee-ot. Not on my computer you don't.
