      can you tell me what is corrupted? I have confirmed that the download links are working fine. The files cannot be corrupt as the links come from Apple servers officially.

        Confirmed – It’s CORRUPTED 🙁

        I’m pc/linux user with new blank hdd on iMac and no install media.

        Downloaded twice, same result.

        With the size of only 1.9GB, something is missing for shure (as older versions are 4GB+).
        Using latest TransMac on PC to create bootable USB immediately says “This disk immage may be damaged or of an unsupported format”.

        Other DMF files are transfered fine with TransMac, but this one fails.

        Does exist some online OS loader on mac?
        Something like linux distros with small ISO footprint, and online installation?
