The reason why this insane message is happening is because as of February 2016, the security certificates that validate these Mac OS X installs seems to have expired. What this means is that when you try to install Mac OS X Mavericks, Yosemite or El Capitan from any USB or external source, the certificate checking process will render your copy of the installer null and void. You will then get the error “This copy of the Install OS X Mavericks application can’t be verified. It may have been corrupted or tampered with during downloading.”

The reason why this works is that you are actually turning your computer into a time machine–and you are telling it to go back to the date February 2nd, 2016. This tricks the certificate into believing that the date is now in the past and allows the installation to resume. You can also redownload any installers to get the new certificates, which are located in your purchase history on the Mac App Store. You would then have to make new installer disks with these new downloaded installers.
