The only things worth mentioning here are: The documentation on tonymacx86 for upgrading to macOS High Sierra worked perfectly for me. Getting past the error was as simple as loading my old config file into MultiBeast, changing the System Definition (Customize › System Definitions) to “iMac 14,2”, running MultiBeast again, and rebooting. This was due the System Definition I set in MultiBeast when I installed El Capitan (“Mac Pro 3,1”). The error shown read something along the lines of: “This version of macOS 10.12 cannot be installed on this computer”. Right out of the gate I ran into my first problem: the App Store wasn’t letting me download the High Sierra installer.

Wifi adapter: TP-Link PCI Express Adapter.

Case: BitFenix Phenom Micro-ATX (Black).

RAM: Crucial Ballistix Sport LT 64GB (DDR4).

Graphics card: EVGA GTX 950 SuperClocked.

Here’s a quick reminder of the specs I’m running: I got it done in a couple of hours with most of that time spent either waiting for High Sierra to download or waiting for High Sierra to install. Granted it’s not quite as simple as downloading and running the installer as you would with a regular Mac, but the tools and documentation provided by the Hackintosh community have never been better.

Hackintosh OS upgrades are renowned for being finicky: it’s one of the main criticisms I hear against them.

My first OS upgrade since building the machine. The time came yesterday to upgrade the OS from El Capitan to High Sierra though. I’ve been running a Hackintosh as my main machine for the last year and a bit, and it’s been steady as a rock. Upgrading my Hackintosh from El Capitan to High Sierra
