OEMden has instructions on how to re-patch the boot with SFOTT but it just does not work for me (error I get is Cannot parse volume.

The one I get from the AppStore does not have this, so I cant boot to it.

Im signed up as an Xcode developer (ha) so I should be able to get it from there if its available, but havent seen it.

EDIT: Would it be possible to use the InstallESD.dmg from a 10.9.2 installer to build a bootable USB drive to install 10.9.5.

I want to create a basic (command line) bootable CD that allows me to run this USB install program.

I found my answer.

I got a copy of Active Boot Disk from LSoft -.

Youre options are pretty limited so I would try this since disk utility cant read and mount the drive.

Maverick Dmg Mac In Terminal

In terminal command run: On another Mac in terminal command: CD to the directory where the dmg file is located type.

I email the SFOTT developer guy OEMDen and if he gets back to me, Ill let you know what he said.

Otherwise Ill just boot to SFOTT and disable auto-update checks.

I have access to an iMac here that our graphics designer uses.

Shes on Mountain Lion, so Ill get the 10.9.5 Mavericks installer that way.
