dariuxzy Posted November 14, 2020 Author Share Posted November 14, 2020 Yeah, the mobo has nothing to do with it ... I tried 2 hours ago to download it from the app store, but at the end of the download it tells me: "An error occurred while installing the selected updates"... now I'm trying again. In any case, I have always used "createinstallmedia" to create the USB. I also downloaded from http://swcdn.apple.com/content/downloads/50/49/001-79699-A_93OMDU5KFG/dkjnjkq9eax1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg but the same error, both on hackintosh and real imac. Thanks for the support EDIT. again "An error occurred while installing the selected updates" Link to comment https://www.insanelymac.com/forum/topic/345719-installer-damaged/#findComment-2744096 Share on other sites More sharing options...
dariuxzy Posted November 14, 2020 Author Share Posted November 14, 2020 I used these two commands: sudo /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil unenroll sudo /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil enroll DeveloperSeed and this time I was able to download it from the app store. I created the USB, and now the installation continues without problems.
