Recently I was installing mac os x Sierra 10.12.6 on my Hp pavilion x360 laptop. The installation was successful. But I am not able to use some of the things on it like touchpad, bluetooth, wifi and the memory it is showing is only 7 mb. 


My laptop's specification are as follows:

Name : HP Pavilion x360 s101tu

Processor : Intel i5 6200U 6th gen

Graphics : Intel HD 520

Ram : 8 gb

Motherboard : 80D1


I want to increase the memory for the acceleration which is 7 mb currently. I have tried to install the kext files namely Lilu.kext and Whatevergreen.kext. But that also have not enabled the memory. 

Please help.

Your iGPU is being reported at 7MB because you do not have graphics acceleration. Full stop. It's not that you want to increase video RAM for graphics, you simply need to apply the correct configuration to achieve full graphics acceleration. Your system will thebn report something like 1536MB for your UHD520.


What you ought to do is:

  1. cache or inject latest Lilu + WEG kexts
  2. keep Clover free of any graphics injection (Lilu + WEG now take care of that)
  3. patch your DVMT, either in BIOS or through Clover on-the-fly kext patches (you can Google for this)


I have already inserted the lilu and Whatevergreen kext files but still not getting 1536 MB video memory.

Already installed these kexts?
- Lilu kext: https://github.com/acidanthera/Lilu
- Whatevergreen kext: https://github.com/acidanthera/WhateverGreen

Do you boot with special boot args?

Is your SMBIOS fitting your CPU generation? - It should MBP13,1

Upload your EFI if you still can't get acceleration
