part 1 and part 2 are not necessary, but they will help if you want to know more about gfx-efi.


find and download the right package in part 3 is the key to success. if you cannot find the package for your video card, you can either abort the mission, or study part 1 and part 2 carefully. this GUIDE is for those who can find the right package in part 3.


all right, the guide begins here. take my 7300GT card as an example.


1. go and visit nVidia topic: http://tinyurl.com/2v4ouz

2. download the 7300gt package

3. find the file which ends with hst, in this case, it's 7300gt.hst

4. open it in text edit

5. drag /Library/Preferences/SystemConfiguration/com.apple.Boot.plist to Desktop (Because com.apple.Boot.plist cannot be modified in its original location)

6. open com.apple.Boot.plist (the one on your desktop) with text edit, the last two lines should be like this:



above these two lines, add the following:


<string>PASTE THE STRING FROM STEP 4</string>

save and quit text edit (command+s, command+q)

7. drag com.apple.Boot.plist (the one on your desktop) to its original location (/Library/Preferences/SystemConfiguration/), when prompted, click authentic.. and replace

8. remove natit, or titan, or nvinject, etc ... (it's located in /System/Library/Extensions/ , remember to back it up first. )

9. IMPORTANT!!! do the following to clear the cache

a. open terminal.app

b. execute the commands below one by one

rm -rf /System/Library/Extensions.mkext

rm -rf /System/Library/Extensions/Caches/

rm -rf /System/Library/Caches/


10. when your machine boots, press F8, type -f, hit enter

11. may God bless your machine...

Ha! copperboy is Bill Yeung.. :)


But seriously, Step 9 is wrong. Those instructions are from Tiger.


On Leopard, the correct commands for Step 9 are as follows

a. open terminal.app

b. execute the commands below one by one

sudo -s

touch /System/Library/Extensions



Step 10 is actually not required as "reboot" in step 9 will build the Extensions.cache before rebooting.

yeah, copperboy is Bill Yeung, and Bill Yeung is copperboy :unsure:


I have always been a Mac fan, but not until the hackintosh became possible did I actually use a fully function Mac OS X. I read agrafuese's how-to before I install the gfx-efi on my hackintosh, and I found there were many information which was not necessery for implementing gfx-efi. So I wrote one simplified tutorial on my own.


Thank agrafuese for his/her how-to; and many thanks to the people who helped me, either on the forum, or on the irc.
