Downloads 1 - 6 are the parts of a zipped disc image of the Install
DVD (game version 1.0). To reassemble the complete disc image, place
all the parts in one folder, then drag the .001 file to The
Unarchiver. This will join all the parts and unzip the archive.

After installing and starting the game, entering the product key below
presents the option to "Play with DVD"

Product Key: KDM2-YNGQ-CZ25-ZA7Z-BDYM-ZYVD

Download 7 is a CD image that contains the invisible SafeDisc bundle
that the game looks for in order to play. Burn this image to a CD,
mount the CD, and the game will play when you click the "Play with
DVD" button from within the game application. Using this CD avoids the
unattractive alternative of burning the full game disc image to a
double layer DVD to achieve the same outcome. Mounted disc images are
not sufficient to play. Also I do not have a No-DVD for this game.

Depending on your setup, you may be given the option to update the
game to version 1.1. The Feral servers will still perform this update,
but when they eventually become unavailable you can perform the update
manually using Download 8 below.

Download 8 contains version 1.1 of the game application but without
the large game data file GridData.dmg. To manually update the game to
v. 1.1, copy GridData.dmg from /Contents/Resources/ in the game
application on the Install disc image over to /Contents/Resources/ in
the application contained in this download. (To access the Contents
folder of an application, control-click the application and select
"Show Package Contents")

Download 9 contains a cracked version 1.1 of the game. To use it,
first update the game using the Download 8. Then unzip this file,
control-click the game application, select "Show Package Contents",
navigate to the MacOS folder and replace the GRID file inside that
folder with the cracked copy in this download. Ignore the Product Key
field when you start the game application and just click "Play". This
crack was made by checking how [Deus Ex: Human Revolution][1] was
cracked and then making similar changes to this game. The instructions
are also based on the instructions to install its cracked versions.
