Tried to use Open Core so I can upgrade my 5,1 to Monterey, but I received the following error. Anyone know what to do?
Corrupted Installer!
Failed to validate installer, cannot continue.
This can generally happen due to a faulty USB drive, as flashing is an intensive process that can trigger hardware faults not normally seen.
STDERR: hdiutil: verify: unable to recognize "/Volumes/Install macOS Monterey/Install macOS Monterey.app/Contents/SharedSupport/SharedSupport.dmg" as a disk image. (image not recognized)
hdiutil: verify failed - image not recognized
