Hello, Thanks for the clarification. Downloading 10.15.3 as we speak..

Hello, Thanks will download 10.15.3 and give it a go. By folder do you mean the fat32 partition with the drivers and kexts etc and boot loader?

Hello, Thanks for that,was thinking it was something I was doing wrong. Do you have a AMD version built with 10.15.3 I can try?

Hello, I have downloaded your AMD catalina 10.15.4 image to install on my Amd Threadripper build. The install proceeds ok until I get to the screen where you select the drive and click install to continue. Instead of beginning the install AMD Catalina jumps back to the Macos utilities screen. Any ideas why it is stuck in this loop? Another thing I found is if I let my PC go to sleep and then wake it and try to install I get a message box come up stating that "This copy of install macos catalina application is damaged and can't be used to install macos" Changing the date/time does not fix this issue.
