（转贴）X1250显卡的解决办法，不知是否有效
在箫心论坛见到的
全文如下：
我干脆直接写脚本给你吧！！
反正我不时也用MAC，但不过我的笔记本显卡为X1600
我的操作系统为MacOSX 10.4.6 Hotiso版
你要确定你的系统干净！！！
打开终端，输入sudo -s 输入密码
这里需要用vi命令编辑三个plist文件
1。在终端编辑/System/Library/Extensions/ATINDRV.kext/Contents/Info.plist文件，把<string>ATY,WORMY</string> 改为<string>display</string> 再把<string>IONDRVDevice</string> 改为<string>IOPCIDevice</string> ，保存退出。
2。在终端编辑/System/Library/Extensions/ATIRadeonX1000.kext/Contents/Info.plist文件，找到IOPCIMatch 修改你的设备ID为 <string>0xXXXX1002</string>这里的四个大X代表了你的设备ID，我的设备ID是71C0，所以我应该改为<string>0x71C01002</string> ,在下面一行，确定你的IOProviderClass 值是 IOPCIDevice，保存退出。
3。在终端编辑/System/Library/Extensions/ATIRadeonX1000GA.plugin/Contents/Info.plist文件，找到<key>100271C0-0000-0000-0000-000a27898d3e</key>，红色部分改为你的设备ID，再找到下面几行的<string>100271C0-0000-0000-0000-000a27898d3e</string>，红色部分改为你的设备ID。
确定这个文件里面的<key>IOProviderClass</key>值是<string>IONDRVFramebuffer</string>。保存退出。
4。在终端输入：
rm /System/Library/Extensions.mkext
rm /System/Library/Extensions.kextcache
kextcache -k /System/Library/Extensions
5。退出终端，用磁盘工具修理磁盘权限。重新启动，完美驱动显卡的系统来了！！
附上我修改的这三个文件的全部内容，以供大家对照参考。

不知是否有效，我的也是X1250，正在下10.4.8。
