How can I customize my Mac's configuration in Game Agent to see what games might run if I upgrade?
Click on the button next to the "System Requirements compared to:" popup menu to open the custom configuration panel. You can then customize your Mac or the standard Apple configurations by clicking "Customize" and then editing the various fields.
Your new custom configuration will appear at the bottom of the "System Requirements compared to:" popup menu.
Clicking on the button again will hide the custom configuration panel.
