Thanks for the direction. So I tested out each of these ig-platform-ids I pulled from Pike's site.
[ 1] : 0x0c060000 - Haswell SDV Mobile GT1
[ 2] : 0x0c160000 - Haswell SDV Mobile GT2
[ 3] : 0x0c260000 - Haswell SDV Mobile GT3
[ 4] : 0x04060000 - Haswell Mobile GT1
[ 5] : 0x04160000 - Haswell Mobile GT2
[ 6] : 0x04260000 - Haswell Mobile GT3
[ 7] : 0x0d260000 - Haswell CRW Mobile GT3
[ 8] : 0x0a160000 - Haswell ULT Mobile GT2
[ 9] : 0x0a260000 - Haswell ULT Mobile GT3
[10] : 0x0a260005 - Haswell ULT Mobile GT3
[11] : 0x0a260006 - Haswell ULT Mobile GT3
[12] : 0x0a2e0008 - Haswell ULT E GT3
[13] : 0x0a16000c - Haswell ULT Mobile GT2
[14] : 0x0d260007 - Haswell CRW Mobile GT3
[15] : 0x0d220003 - Haswell CRW GT3
[16] : 0x0a2e000a - Haswell ULT E GT3
[17] : 0x0a26000a - Haswell ULT Mobile GT3
[18] : 0x0a2e000d - Haswell ULT E GT3
[19] : 0x0a26000d - Haswell ULT Mobile GT3
[20] : 0x04120004 - Haswell GT2
[21] : 0x0412000b - Haswell GT2
[22] : 0x0d260009 - Haswell CRW Mobile GT3
23 0x04160002
24 0x0a260008
These 4 get me to the desktop with no GPU acceleration. System profiler lists HD5000 4MB
0x04060000, 0x04120004, 0x04160002, 0x0a260008
All of the other IDs I can only get in to through screen share. System profiler lists HD5000 1536MB
I saved an IOReg each time I tried a different ig-platform-id.
So thats what I have so far.
Attached is the IOReg from the ig-platform-id of 0x0a260008.
Let me know your thoughts.
0x0a260008 is not a valid ig-platform-id. It serves only to disable the graphics drivers. Your results in this ioreg are the expected results.
Use a valid ig-platform-id (0xa260006 usually), and provide ioreg.
Your profile provides no details on your hardware...
Please provide complete details
in your profile/signature
(Profile/Settings link in upper right corner of this site)
Mobo: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution
For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768
Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.
Note: When specifying your bootloader, if using Clover legacy, please be sure to specify "Clover legacy"). Specifying "Clover" will be assumed as "Clover UEFI"
