对于有强迫症的可以往下看，写给新手的

对于安装好了黑果的，但是没有亮度调节的（小太阳），我也是爬了好多帖子才找到的，

首先下载下面两个文件并安装修复权限：
clover放到clover/kexe/10.10下面变色龙放到e/e下面

ACPIDebug.kext.zip (24.85 KB, 下载次数: 468) 放到s/l/e下面记得修复权限

首先修改DSDT 在DSDT最后面添加 RMDT method，

Device (RMDT)
{
Name (_HID, "RMD0000")
Name (RING, Package (0x0100) {})
Mutex (RTMX, 0x00)
Name (HEAD, Zero)
Name (TAIL, Zero)
Method (PUSH, 1, NotSerialized)
{
Acquire (RTMX, 0xFFFF)
Add (HEAD, One, Local0)
If (LGreaterEqual (Local0, SizeOf (RING)))
{
Store (Zero, Local0)
}
If (LNotEqual (Local0, TAIL))
{
Store (Arg0, Index (RING, HEAD))
Store (Local0, HEAD)
}
Release (RTMX)
}
Method (FTCH, 0, NotSerialized)
{
Acquire (RTMX, 0xFFFF)
Store (Zero, Local0)
If (LNotEqual (HEAD, TAIL))
{
Store (DerefOf (Index (RING, TAIL)), Local0)
Increment (TAIL)
If (LGreaterEqual (TAIL, SizeOf (RING)))
{
Store (Zero, TAIL)
}
}
Release (RTMX)
Return (Local0)
}
Method (COUN, 0, NotSerialized)
{
Acquire (RTMX, 0xFFFF)
Subtract (HEAD, TAIL, Local0)
If (LLess (Local0, Zero))
{
Add (Local0, SizeOf (RING), Local0)
}
Release (RTMX)
Return (Local0)
}
Method (P1, 1, NotSerialized)
{
PUSH (Arg0)
}
Method (P2, 2, Serialized)
{
Name (TEMP, Package (0x02) {})
Store (Arg0, Index (TEMP, Zero))
Store (Arg1, Index (TEMP, One))
PUSH (TEMP)
}
Method (P3, 3, Serialized)
{
Name (TEMP, Package (0x03) {})
Store (Arg0, Index (TEMP, Zero))
Store (Arg1, Index (TEMP, One))
Store (Arg2, Index (TEMP, 0x02))
PUSH (TEMP)
}
Method (P4, 4, Serialized)
{
Name (TEMP, Package (0x04) {})
Store (Arg0, Index (TEMP, Zero))
Store (Arg1, Index (TEMP, One))
Store (Arg2, Index (TEMP, 0x02))
Store (Arg3, Index (TEMP, 0x03))
PUSH (TEMP)
}
Method (P5, 5, Serialized)
{
Name (TEMP, Package (0x05) {})
Store (Arg0, Index (TEMP, Zero))
Store (Arg1, Index (TEMP, One))
Store (Arg2, Index (TEMP, 0x02))
Store (Arg3, Index (TEMP, 0x03))
Store (Arg4, Index (TEMP, 0x04))
PUSH (TEMP)
}
Method (P6, 6, Serialized)
{
Name (TEMP, Package (0x06) {})
Store (Arg0, Index (TEMP, Zero))
Store (Arg1, Index (TEMP, One))
Store (Arg2, Index (TEMP, 0x02))
Store (Arg3, Index (TEMP, 0x03))
Store (Arg4, Index (TEMP, 0x04))
Store (Arg5, Index (TEMP, 0x05))
PUSH (TEMP)
}
Method (P7, 7, Serialized)
{
Name (TEMP, Package (0x07) {})
Store (Arg0, Index (TEMP, Zero))
Store (Arg1, Index (TEMP, One))
Store (Arg2, Index (TEMP, 0x02))
Store (Arg3, Index (TEMP, 0x03))
Store (Arg4, Index (TEMP, 0x04))
Store (Arg5, Index (TEMP, 0x05))
Store (Arg6, Index (TEMP, 0x06))
PUSH (TEMP)
}
}

复制代码

放到DSDT的最后就可以了
或者可以添加补丁源：http://raw.github.com/RehabMan/OS-X-ACPI-Debug/master 打补丁

选中补丁点击应用！
在DSDT搜索 IGPU.DD02亮度函数应该会看到两处

Method (_Q8E, 0, NotSerialized)
{
Store (0x70, P80H)
If (LGreaterEqual (OSYS, 0x07D6))
{
Notify (^^^IGPU.DD02, 0x86)
}
}
Method (_Q8F, 0, NotSerialized)
{
Store (0x71, P80H)
If (LGreaterEqual (OSYS, 0x07D6))
{
Notify (^^^IGPU.DD02, 0x87)
}
}

复制代码

在_Q8E下面添加\rmdt.p1("EC0._Q8E enter") 和\rmdt.p1("EC0._Q8E exit") 注意红色字体，修改成你自己的！！！
代码变成：

Method (_Q8E, 0, NotSerialized)
{
\rmdt.p1("EC0._Q8E enter")
Store (0x70, P80H)
If (LGreaterEqual (OSYS, 0x07D6))
{
Notify (^^^IGPU.DD02, 0x86)
}
\rmdt.p1("EC0._Q8E exit")
}
Method (_Q8F, 0, NotSerialized)
{
\rmdt.p1("EC0._Q8F enter")
Store (0x71, P80H)
If (LGreaterEqual (OSYS, 0x07D6))
{
Notify (^^^IGPU.DD02, 0x87)
}
\rmdt.p1("EC0._Q8F exit”)
}

复制代码

记得保存后退出！！重启系统！！！
打开Launchpad，找到控制台打开
在右上角的输入框里面输入： ACPIDebug
我这里显示一条信息：

不要关闭控制台按FN键+F5（减亮度）或者 FN键+F6（加亮度）
看控制台输出的信息如果FN+F5输出的是 _Q8E 那就是Q8E是减暗度 FN+F6 如果不出错的话就是Q8F
再次打开MACIASL来修改DSDT，点击打补丁输入下面内容（注意【】里面需要修改包括【】）

# Make EC-based brightness up/down work with RehabMan VoodooPS2 ACPI keyboard mechanism
into method label _Q【改成8E 这里是加亮度的键值】 parent_label EC0 replace_content
begin
// Dell code for brightness up\n
Notify (PS2K, 0x0206)\n
Notify (PS2K, 0x0286)\n
end;
into method label _Q【改成8F 这里是减亮度的键值】 parent_label EC0 replace_content
begin
// Dell code for brightness down\n
Notify (PS2K, 0x0205)\n
Notify (PS2K, 0x0285)\n
end;

复制代码

修改好的代码：

# Make EC-based brightness up/down work with RehabMan VoodooPS2 ACPI keyboard mechanism
into method label _Q8E parent_label EC0 replace_content
begin
// Dell code for brightness up\n
Notify (PS2K, 0x0206)\n
Notify (PS2K, 0x0286)\n
end;
into method label _Q8F parent_label EC0 replace_content
begin
// Dell code for brightness down\n
Notify (PS2K, 0x0205)\n
Notify (PS2K, 0x0285)\n
end;
