What works and What doesn't:

Since intelbluetooth card is not officially supported in MacOS, it might be laggy when it comes to pairing.

Exchanging bluetooth card that support MacOS would be a great idea.

3.5mm headphone jack works yet poor sound quality. Use bluetooth connections instead.

Every function works quiet well.

SMBIOS:

This hackintosh EFI uses MacBookPro 14,1 SMBIOS.

Create your own MacBookPro 14,1 SMBIOS with GenSMBIOS

Open terminal and run install.sh from TOOLS EFI MOD/ComboJack_Installer.

MacOS bootable USB creation:

setup_var 0x4ED 0x0

To set DVMT to Max, type:

setup_var 0x796 0x3 

Post Install regarding Sleep:

To improve Sleep and battery life, I recommand to follow those things:

• Disable Airdrop
• Disable Powernap and internet awake

**pmset options: **

sudo pmset standby 0
sudo pmset autopoweroff 0
sudo pmset powernap 0
sudo pmset proximitywake 0
sudo pmset tcpkeepalive 0

(Experimental) Enable S4 Sleep:

You need to adjust some parameters in config.plist in order to enable S4 (Hibernation) state.

ThirdPartyDrives = True (Set True if you are using 2.5 inch SSD or mSATA M.2 SSD)

HibernateMode = NVRAM

And you need to adjust your hibernationmode by pmset.

sudo pmset -a hibernationmode 25

Hibernation function should work after adjusting these values.

There are some issue, however

• After waking up from S4 sleep, you will face a blackscreen. Wait until the display turn off or press the power button to turn off the display.

After waking up, your display will properly work.

• Touchpad will not work after waking up from hibernation. (This needed to be fix!)
