The version of the Chameleon bootloader that comes with the iDeneb 1.3 (well, UInstaller) is ancient. The new Chameleon bootloader version 2.0 is amazing, with a GUI, expanded features, and theme support, there’s no reason why you shouldn’t upgrade!
The first thing you need to do is go ahead and grab the Chameleon v2 RC2 bootloader package here: http://chameleon.osx86.hu/file_download/36/Chameleon-2.0-RC2-r640.pkg.zip
The next thing you need to do is go ahead and open Terminal (Applications > Utilities > Terminal.aap) and enter the following, hitting enter after every line:
rm -rf /.Chameleon
All done with Terminal, so you can go ahead and close it.
Now, open the Chameleon v2 Installer package and click through the installer until you reach the Customize button, and uncheck the “Extras (kexts)” box. Finish the install.
That’s all! You’ve just upgraded your bootloader!
