爱华网Intel HD4000集显驱动在系统10.8和10.7.5以后的系统中都自带了驱动。可是安装黑苹果的人还是有很多人驱动不了，包括我自己的E1 471也没有能驱动。所以写这一贴，只能说是大家相互探讨驱动方法而以，给没有驱动成功的人一点尝试另外一种驱动方法而以。
上面这两张截图是前两天一个网友我帮他用EFI String驱动成功的i3 3225的截图
先来讨论下DSDT驱动。其实DSDT驱动和我们的HD3000驱动类似，只是把硬件ID写到IGP0或是GFX0位置中，让系统识别硬件，主要起作用的代码为以下几行：
"AAPL,ig-platform-id",
Buffer (0x04)
{
0x0A, 0x00, 0x66, 0x01
},
其中这里的0166是你的显卡硬件ID，当然这里可以根据你的硬件修改成你的硬件ID代码。
完整的DSDT代码如下：
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x14)
{
"AAPL,slot-name",
Buffer (0x08)
{
"Slot -1"
},
"built-in",
Buffer (One)
{
0x01
},
"AAPL,HasPanel",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},
"AAPL,Haslid",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},
"AAPL,backlight-control",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},
"@0,backlight-control",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},
"@0,AAPL,boot-display",
Buffer (0x04)
{
0x01, 0x00, 0x00, 0x00
},
"device-id",
Buffer (0x04)
{
0x66, 0x01, 0x00, 0x00
},
"AAPL,ig-platform-id",
Buffer (0x04)
{
0x03, 0x00, 0x66, 0x01
},
"hda-gfx",
Buffer (0x0A)
{
"onboard-1"
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
其中含有亮度相关的代码，已经证实hd4000无法出现小太阳，亮度滑块调节也没用实际用处。各位可以自行删除。
最后提醒各位，代码模板有通用性不代表AAPL,ig-platform-id有通用性，各位需要自己尝试自己的id。

另外使用AAPL,ig-platform-id的EFI String驱动 Intel HD4000显卡驱动。其实有侦测HD4000的办法，但是我们还是使用笨办法吧！一个一个的试你的EFI String的值，反正HD4000EFI String的值总共没几个，总有一个适合你的。
首先请看平台列表：
ig-platform-id: 01660000, Stolen RAM for FB: 96MB, Pipes: 3, Ports: 4, FBMem: 3
ig-platform-id: 01660001, Stolen RAM for FB: 96MB, Pipes: 3, Ports: 4, FBMem: 3
ig-platform-id: 01660002, Stolen RAM for FB: 64MB, Pipes: 3, Ports: 1, FBMem: 1
ig-platform-id: 01660003, Stolen RAM for FB: 64MB, Pipes: 2, Ports: 2, FBMem: 2
ig-platform-id: 01660004, Stolen RAM for FB: 32MB, Pipes: 3, Ports: 1, FBMem: 1

ig-platform-id: 0166000B, Stolen RAM for FB: 32MB, Pipes: 2, Ports: 3, FBMem: 2
ig-platform-id: 01620005, Stolen RAM for FB: 32MB, Pipes: 2, Ports: 3, FBMem: 2
这些都是不同的管线端口配置的HD4000，至少有一个能成功注入驱动！而且台式机笔记本都可以使用！
如果你不知道该用哪个，首先你可以试试01620005，以上成功的截图就是用05驱动的。
使用方法：把以下其中之一代码填入到你的org.chameleon.Boot.plist里，并且按照表明的FB修改BIOS里的共享显存大小。
记住是显存（Internal Graphics Memory Size）的大小，不是DVMT的大小！DVMT大小永远设为MAX！并且在org.chameleon.Boot.plist 设置GraphicEnabler＝No

下面为举例：
比如我想试用05驱动我的HD4000
那么org.chameleon.Boot.plist的样子应该是这样的：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"[]>
<plist version="1.0">
<dict>
<key>GraphicsEnabler</key>
<string>no</string>
<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>
</dict>
</plist>
总结：通过以上两种方法驱动 Intel HD4000的显卡都不依赖特殊版本的变色龙，只要你的硬件ID匹配正确，那么都应该能驱动的，但不是绝对的。我对我的E1 471采用EFI String却没有驱动成功，当时驱动最好的就是四分屏了，估计与内存或是主板设置有关系，可是本本的主板是没有显存设置的，不知道添加内存能不能驱动好E1－471的i5 3210的本本！具体请各位网友测试，如果能在本贴中回复那就更好了！
2012年11月21日添加补充：
笔记本使用以下代码也能驱动你的集显HD4000，具体情况请自行测试：
<key>device-properties</key>
<string>5e0000000100000001000000520000000100000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601</string>
另外添加一组HD4000的代码，希望网友使用后反馈信息：
<key>device-properties</key>
