[Guide] Lenovo Yoga 3 14 [Broadwell, HD5500]

[RehabMan]

Can you help me with this?

Probably you didn't set DVMT-prealloc to 64mb (assuming you don't have a UHD screen).

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"

Wow, this is more important than wifi. How can I enable CPU Power Management?

Did you use the extended script from piker?

The generated SSDT-aml is in my first post.

That script is not from Pike...

The official 'Beta' branch has the additional CPUs.

I found that I have to manually patch the binary of AppleIntelBDWGraphicsFramebuffer.kext with 0xED or hex friend and fill 16160002 on both blank of graphic on clover setting (which seems unnecessary on Sierra) in order to solve this problem, for the clover patch on that didn't work properly.
However, after I update the system from AppStore, the patch works again and I don't need to patch that again.
I think you can try this method cause I think we have the same problem. (It took me almost two week to figure out that...sad

Keep in mind that Clover can only patch a kext that is in cache, or loaded without caches.
If you're transitioning from no graphics kexts loaded to attempting a boot with Clover KextsToPatch that apply to the graphics kexts, you must boot without caches, then rebuild cache before you can boot normally (with caches).

Hello

Thank you for the quick reply,
I managed to work the graphics card simply by changing ig-platform-id
I used 0x16260006 in Clover Configurator

It is the same as used in post #1, config_FULL.plist.
