Q: Can I use createinstallmedia in Mavericks to make a Yosemite Install USB?
Hello, the last line of Apple's support page on this topic says createinstallmedia "is only intended to be used with the version of the OS X Installer app it came with," but this MacWorld article implies that I can use Lion, ML, Mavericks, or Yosemite to make a Yosemite Install USB.
I have a MBP with Retina Display running Mavericks and can download the (Yosemite) Install OS X.app. Can I use the createinstallmedia command on Mavericks with the Yosemite installer to make a bootable Yosemite install USB or must I upgrade first?
Has anyone used createinstallmedia in Mavericks to make a (working) Yosemite Install USB?
Thank you.

Ok, so my plan now is to get a 32GB USB stick, make four 8GB partitions on it, and make install volumes for Yosemite, Mavericks, Mountain Lion, and Snow Leopard (for legacy machines) on each. For Yosemite and Mavericks, I will use createinstallmedia, and for Snow Leopard, I will restore the DVD to the USB in Disk Utility. How about for Mountain Lion -- createinstallmedia or restore the ML InstallESD.dmg via Disk Utility?
Thank you.
What you're suggesting to do is what I have done with a 32GB thumb drive but only for ML, Mavericks and Yosemite. I don't have any Macs that can run SL. And I'm not interested in running Lion for any reason even though I have a Mac that can run Lion.
I always use the InstallESD.dmg and Disk Utility/Restore for OS X Mountain Lion and Lion. I use the createinstallmedia with Mavericks and Yosemite only. I don't even know if it's even in the Install OS X Mountain Lion.app file. I doubt it.
Also, I just ran that createinstallmedia within Mountain Lion against the Yosemite install app and it created a USB thumb drive installer for Yosemite.
