ATI Radeon Mobility 7500 Driver Pack
These are the files currently known to work with the Radeon Mobility 7500 Video Card. These files are not guaranteed to work with anything else.
*USE AT YOUR OWN RISK!*
I do not accept responsibility for anything these files do to your machine. That is your responsibility.
File List:
ATIRadeon.kext
ATIRadeonGA.plugin
ATINRDV.kext
ATIRadeonGLDriver.bundle
ATIRadeonDVDDriver.bundle
AGPGart.kext
Callisto.kext
CallistoHAL.kext
OpenGL.framework
Quartz Extreme Check.app
Instructions:
1. Run the Installer Package. Do NOT reboot yet.
2. Open Terminal and enter in the following
ioreg -l
1. Locate AGP in the output. It will most likely be listed as AGP@1, but your machine may differ. You will see "compatible" = <"pcixxxx,xxxx","pciclass,xxxxxx">
The first set is the item you should note.
Enter the following at Terminal:
sudo nano /System/Library/Extensions/AGPGart.kext
Locate:
<key>IONameMatch</key>
<array>
<string>pci8086,2561</string>
</array>
Change this to reflect the information you got above.
cntrl-o, enter, cntrl-x
Now enter the following at the Terminal prompt:
sudo chown -R root:wheel /System/Library/Extensions/AGPGart.kext
sudo chmod -R 755 /System/Library/Extensions/AGPGart.kext
Now enter the following at the Terminal:
sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
Add the following in the middle somewhere after the Kernel key, but before a Quiet Boot or Boot Graphics key.
<key>Kernel Flags</key>
<string>-f</string>
cntrl-o, enter, cntrl-x
Now open Disk Utility to be safe (this stepp is not required, but highly recommended) and run Repair Permissions on your disk.
Reboot and pray.
Thanks to omni, jobo10 and all the others who created their parts of this driver pack. Also thanks to those in the OSx86 Community who helped work on this card over the past year.
中文翻译：
1、Run the Installer Package. Do NOT reboot yet.
运行ati安装包，完成后别重启
2、Open Terminal and enter in the following
打开终端，输入下面的命令：
ioreg -l
3、定位输出文件中的AGP@1，在此段下面有"compatible" = <"pcixxxx,xxxx","pciclass,xxxxxx">的语句，记住其中第二个xxxx，比如t40中的ati是pci8086，3341
4、在终端中输入
sudo vim /System/Library/Extensions/AGPGart.kext/Contents/Info.plist
然后定位到下面位置：
<key>IONameMatch</key>
<array>
<string>pci8086,2561</string>
</array>
将此处的pci信息改为之前找到的，比如改为pci8086,3341
退出vim编辑模式，输入:wq保存并退出。
5、在终端中输入下面命令，修改相应文件夹的操作权限
sudo chown -R root:wheel /System/Library/Extensions/AGPGart.kext
sudo chmod -R 755 /System/Library/Extensions/AGPGart.kext
6、在终端中输入下面命令
sudo vim /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
增加下面的内容
<key>Kernel Flags</key>
<string>-f</string>
然后保存退出。
7、打开磁盘管理，选择mac的安装分区，点击修复权限，完成后重启机器。

其他的中文说明，个人按照那个方法后不成功，所以，还是看英文原版的好。
