Chameleon 2 RC4 patched with 915resolution for Snow Leopard and Intel GMA X4500

!!Attention: this post is old, you can find an updated version here!!

Unlike the previous HowTo, this time I’ve made the things much simpler. The goal is to get 1336×768 resolution on Intel GMA X4500 with Snow Leopard, so I’ve patched and compiled Chameleon 2 RC4 bootloader, integrating the 915resolution patch, including the strings for GM45 chipset. So you don’t need anymore to have Linux, Grub2 and sacred spirit installed!

All you have to do is replace your Chameleon bootloader in the root of leo filesystem (/boot) with the one supplied in the archive below.

Note: you have to install Chameleon 2 RC4 from the original package first!

I’ve tested it with my Dell Inspiron 1545 (Intel GMA X4500) and got 1336×768 resolution with Snow Leopard 10.6.2, Hazard release, without any further patch!

Obviously, you can test it with other Intel chipsets, such as 915, 945, 500 .. and hope it works.

This is the download link:

—Edit: Updated to support more Chipsets (Intel G31, G41, and G45):

—Edit: Latest build, with source code:

Note: delete any “GraphicsMode=…” flag from /Library/Preferences/SystemConfiguration/ and /Extra/

-Currently, this is the only method to boot Snow Lepard kernel in 64bit mode with this card!!

All the other patches (applied to IntelGMAX3100.kext, IntelGMAX3100FB.kext and dsdt.aml) work only in 32bit mode, and give no benefits other than getting native resolution. So, until someone patches the modules or implements QE/CI, there is no need of using them!
