I first thought of SecuROM, a CD/DVD copy protection scheme applied to computer game discs: https://en.wikipedia.org/wiki/SecuROM
That's what I thought as well. I read the headline and was surprised that SecuROM was still around and was confused what it had to do with Apple... until I saw your comment.
A DRM scheme that often failed to work and had a limit to the amount of installs.
