Problem 4: Monitor goes to sleep at the end of the boot sequence when using iMac15,1 or iMac17,1 or MacPro 6,1 system definition
NOTE: there really isn't a reason to use any of these profiles with the exception of those using X99 systems might want to consider using MacPro6,1. Likely you will run into more troubles than it is worth after each update.
Fix: modify the AppleGraphicsDevicePolicy.kext as pointed out by PikeRAlpha here.
For the iMac15,1 locate the board-id "Mac-42FD25EABCABB274" and change string below it from "Config2" to "none". For the MacPro6,1 you will do the same thing but for the board-id "Mac-F60DEB81FF30ACF6". For the iMac17,1 you'll have to see which board-id is declared in your config.plist SMBIOS: "Mac-B809C3757DA9BB8D" or "Mac-65CE76090165799A" or "Mac-DB15BD556843C820" and change the appropriate entry to "none".
Save the file by pressing Ctrl+O, then enter.
Exit by pressing Ctrl+X
Rebuild the kernel cache using the following two commands in terminal:
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches
Reboot
NOTE: you may need to use kext-dev-mode=1 if not already using it to allow the modified kext.
1. 两块 SSD 256GB都先接好,第二块的数据线暂时不要接先.
2. 用EI Captian 的U盘 UEFI 模式启动第一块硬盘,安装 EI Captian,2个区 , $diskutil list 结果如下 :
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *240.1 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS EI Captin 99.8 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
4: Apple_HFS 未命名 139.2 GB disk0s4
3. 拔下第一块硬盘的数据线,接上第二块硬盘的数据线,装 Windows,注意一定要从UEFI U盘模式启动,才能把windows10安装在 GPT硬盘中。windows 10分区格式如下:
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *240.1 GB disk1
1: Windows Recovery 471.9 MB disk1s1
2: EFI NO NAME 104.9 MB disk1s2
3: Microsoft Reserved 16.8 MB disk1s3
4: Microsoft Basic Data 106.8 GB disk1s4
5: Microsoft Basic Data 新加卷 132.7 GB disk1s5
