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.
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.

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!)
