Make Yosemite Installer USB drive that does not require internet access There are plenty of instructions on how to to make a Yosemite installer USB drive that work using either the createinstallmedia program or Diskmaker X. However, when I take that drive to a machine which cannot be connected to the internet or to wifi, the installer tells me the OS cannot be installed because an internet connection is required. For all previous versions of the OS, it was trivial to do this with Diskmaker X because the installer did not require internet access.

Assuming this is possible, how can I make an installer USB drive which will not require network access?
I just noticed that 10.10.3 was available and tried it again. I am guessing that others noticed this bug and reported the problem for 10.10.2. createinstallmedia works as expected.
