Apple's installer failed. Bad installer app maybe?

Tried 3 different Macs and downloaded the installer once more from Apple, no dice. I've even disabled our EPP in case it was being blocked. Any other suggestions?

Hi my colleague assisted me with this.

Tried installing manually using the instructions here:

https://github.com/MagerValp/AutoDMG/wiki/How-Does-AutoDMG-Work

The installer command fails with the error above. Steps to reproduce:

UserInfo={NSLocalizedDescription=Volume contains a macOS or OS X installation which may be damaged., NSLocalizedFailureReason=Volume contains a macOS or OS X installation which may be damaged.}.

Tried running the Apple USB media creation tool with known good USB stick, and the command succeeded (verifying that the installer should be good):

https://support.apple.com/sl-si/HT201372

Can you confirm that the installer command above is valid?

I'm also having trouble running the OSInstall.mpkg directly:

May 12 18:49:22 installer[958] : OSIInstallElement <OSIInstallRecoverySystemElement: 0x7ff935ed0ef0> errored out: Error Domain=com.apple.osinstall Code=-31 "A file required for installation could not be found." UserInfo={NSLocalizedDescription=A file required for installation could not be found.}

No description of what the file is, or what is expected.

Also verified the download by creating a bootable USB stick.

Could something have changed in a recent update to the installer from Apple?

Your suggestion worked. I will check the FAQs next time. Thank you.
