To unlock the boot.efi fi le in CoreServices use the following command in terminal. Your fi le
path may differ depending on what you have named your USB drive.

Modifying the installer to recognize/allow the Mac Pro
1.
You will need to add two board ID's to the OSInstall.mpkg Distribution fi le. To do this you
will need to install the Flat Package Editor which can be found on
https://developer.apple.com/downloads/index.action
. You will need to login and then
search for "Auxiliary Tool
s”
.
2.
Download the “Late July 2012” dmg
3.
Once downloaded, mount the DMG and right click PackageMaker then
show the contents
.
4.
Browse to the /Contents/Resource folder and you will see the Flat Package Editor there.
Copy that to your Utilities folder.
5.
Once you have the Flat Package Editor, use it to open the OSInstall.mpkg found on the
installer drive at System/Installation/Packages.
6.
Click and drag the Distribution fi le to the desktop
.
7.
Open up the TextEdit app and go to its preferences and uncheck “Smart Quotes”.
8.
Now open the distribution fi le using TextEdit app.
9.
Scroll down a little bit until you see "var platformSupportValues=[..."
10.
That is followed by a bunch of board ID's. For the Mac Pro 1,1 and 2,1 you will need to add
"Mac-F4208DC8","Mac-F4208DA9". Add them to the end of the list.
11.
If you are not using a Mac Pro then you will need to get your board ID by entering this
command in terminal:
ioreg -lp IOService | grep board-id
12.
Make sure that you follow the same syntax as the other entries and make sure that you
have only opening quote marks around what you type in. You may have to copy and paste
the quote marks from an existing entry. If your closing quote after the boardID looks italic
then it will not work.

Save the edited Distribution fi le.

In the Flat Package Editor window with the Distribution fi le highlighted click delete.
15.
Now drag the edited Distribution fi le into the window and save the p
ackage
fi le.
16.
Also in the Packages folder you will need to modify the InstallableMachines.plist fi le with
the same to above board IDs again following the syntax.
17.
Finally you have to modify the PlatformSupport.plist located in the System/Library/
CoreServices folder, again adding the two board IDs in the correct syntax.

Installing

1.
Boot from the thumb drive by either selecting the startup disk in system preferences or by
holding option after the boot chime. It will probably take a little while to boot.
2.
Follow the normal OS X install process.
3.
After it is done the machine will restart and then you will continue setup.
4.
Done.
