I've an older iMac (27" mid 2010) that I'm trying to install macOS High Sierra onto. The install just keeps failing. I've redownloaded / recreated the installer several times and even tried installing to an empty partition but nothing worked. A snippet of the error log output is below:
Would be nice to get this iMac usable again so any help is appreciated. (Target Display Mode and a 32-bit version of EyeTV 3 prevent me from trying the OpenCore Legacy Patcher on this iMac).
Code:
NSFilePath = "/Volumes/Untitled/.OSInstallSandboxPath/Root";
NSLocalizedDescription = "An error occurred while extracting files from the package \U201cCore.pkg\U201d."
NSURL = "Core.pkg - file:///Volumes/InstallESD/Packages/OSInstall.mpkg"
NSUnderlyingError = "Error Domain=PKXARArchiveErrorDomain Code=101 \"archive verify failed\"
