Matgen84 Posted October 2, 2020 Share Posted October 2, 2020 Hi all users I don't know if it's the right place to post my issue. I download 3 times Full Catalina 10.15.7 for a clean installation and try 2 USB stick without success: Panic cpu 0 failed to validate root image against chunklist. Screenshot below. I try Clover and Opencore, same issue. Maybe Catalina 10.15.7 installer is buggy ??? Any ideas, please. Spoiler Link to comment Share on other sites More sharing options...
fusion71au Posted October 2, 2020 Share Posted October 2, 2020 Hi @Matgen84, Try verifying SHA1 hashes of BaseSystem.dmg and InstallESD.dmg inside your Installer.app. Here are mine for 10.15.7 "Install macOS Catalina.app"... fusion71au@fusion71ausiMac ~ % shasum /Applications/Install\ macOS\ Catalina.app/Contents/SharedSupport/BaseSystem.dmg 659df693220f543976e8ce22fd3cd025200bf8d4 /Applications/Install macOS Catalina.app/Contents/SharedSupport/BaseSystem.dmg fusion71au@fusion71ausiMac ~ % shasum /Applications/Install\ macOS\ Catalina.app/Contents/SharedSupport/InstallESD.dmg dee249c729ef80c6d2b8b09f74cdcc0e5b352984 /Applications/Install macOS Catalina.app/Contents/SharedSupport/InstallESD.dmg If the hashes are the same, also check your OC config.plist/Misc/Security/DmgLoading setting (mine set to "Any")...

I try to boot with Opencore. This setting doesn't exist in Clover (new) and his config.plist.... Very strange issue, it(s the first time since I download and create USB Installer for macOS Link to comment Share on other sites More sharing options...
fusion71au Posted October 3, 2020 Share Posted October 3, 2020 (edited) @Matgen84, If BaseSystem.dmg and InstallESD.dmg are the same, maybe the problem lies with the other files in your /Catalina/Install\ macOS\ Catalina.app/Contents/SharedSupport? AppleDiagnostics.chunklist AppleDiagnostics.dmg BaseSystem.chunklist InstallInfo.plist Try replacing the files in your SharedSupport folder with attached files from my 10.15.7 Installer.app SharedSupport folder. Out of curiosity, did you download the installer from Official Mac App Store or did you use a utility like @crazybirdy's installScript_1016fullapp to download from Apple Software Catalog? Maybe there is some App Store signature required? 14 hours ago, Matgen84 said: I use @crazybirdy as usual to download regular or developer beta. Note: I don't understand the modification date in one of your file 13 hours ago, Matgen84 said: @fusion71au Right, the problem lies to the other files. Why that is the question ? In my case, I downloaded the Catalina 10.15.7 installer app from Mac App Store instead of using @crazybirdy's script. To make the installer USB, I just used Apple's createinstallmedia utility. Maybe the strange forward dating on BaseSystem.chunklist and InstallInfo.plist explains the difference why it now works when you replaced the files? Not really sure myself...

Matgen84 Posted October 3, 2020 Author Share Posted October 3, 2020 @fusion71au Right, the problem lies to the other files. Why that is the question ? To make USB, I use DiskMaker X or Install Disk creator: both apps who works fine usually. If you any other ideas! Thanks. Link to comment Share on other sites More sharing options...

You can try another USB sticky, the USB sticky could have some issue if shasum is fine. Link to comment Share on other sites More sharing options...

I think it is not full installer app issue if shasum is ok. Kernel patch is the other unnecessary option to try it. It could USB disk issue.

I also download 3 times 10.15.7 full app with your script and create USB Installer, also 3 times. Very strange ! The only thing that I didn't try is to manually download Catalina with your script.
