Maybe you need to download the latest installer from App Store: https://itunes.apple.com/us/app/macos-high-sierra/id1246284741?ls=1&mt=12 Quote Link to comment Share on other sites More sharing options...
Guest 5T33Z0 Posted July 24, 2022 Share Posted July 24, 2022 I did install High Sierra on my laptop 2 weeks ago without issues. But with HS you have to use some additional settings like blocking the MATS table (if present )as well as enabling "Normalize Headers" (ACPI/Quirks in OpenCore) or "Fix Headers" (Clover).

$tealth Posted July 25, 2022 Author Share Posted July 25, 2022 @ricoc90 @Cyberdevs and @5T33Z0, I did all the the steps that you have mentioned but the installer fails. I guess High Sierra is cursed on my computer I tried to install Via El Capitan no luck , Via Sierra no luck. I guess some problem with the apple installer. 😃 or may be I am wrong.
