Undaunted, I decided to try a new approach. I was perplexed, so I tried to kick it off a couple of times in case I just had a bad download.

Instead, the soft reboot would happen and the installer would attempt to create the special volume, but said partition never got created. With Public Beta 7 and Developer Preview 8, that process didn’t go as it should have for me. It might take another reboot or two before the beta is fully updated, so you have to watch Clover and make sure it’s selecting the correct option. You have to make sure the Clover boot loader selects the correct volume, and then the update proceeds. It creates a special software update volume on your hard drive, and then reboots. The machine soft-reboots into an installer that is supposed to get things ready. When you update Hackintosh High Sierra, things are different. That’s not necessarily the case with a Hackintosh. You don’t have to think about what it’s doing when it reboots, because it always boots from the correct volume. When you update your beta build on a real Mac, it’s almost seamless. The Way High Sierra Updates Proceed on Hackintosh Here’s what seems to have changed in the latest developer and public beta builds. I certainly never needed it when I tried to update Hackintosh High Sierra. This wasn’t universal, and I didn’t have to do it with my build at the time.

For the first beta build, Developer Preview 1, some Hackintosh users found they needed to input a Firmware Features value into their ist files. This isn’t a new obstacle, but it’s one I thought we were past. Finally, after some research and tinkering, I was able to update Hackintosh High Sierra successfully. Then I tried installing Developer Beta 8, and had similar symptoms. I discovered it on my own Hackintosh when I tried first to update to High Sierra Public Beta 7. Apple seems to have upped the ante a bit for Hackintosh users who want to run the latest beta build. There’s another obstacle to installing or upgrading the latest version of macOS High Sierra on a Hackintosh, but I’ve got an answer that worked for me.
