[QUOTE="Randy B. Singer, post: 1864207, member: 190607"] That doesn't mean what it says. It means that the copy of the Mac OS that you have has an expired certificate. Do this, which will eliminate the problem: 1. Go into the Applications folder. 2. Find the Installer for macOS in your Applications folder 3. Right-click (or Control-click) on the installer and choose “Show Package Contents”. 4. Open the folder named “Contents”. 5. Open the folder named “SharedSupport”. 6. Delete the file named “InstallInfo.plist”. 7. Enter your administer password to confirm. 8. Now the installer for MacOS will work perfectly. [/QUOTE]
