EFI Folder for the Xiaomi Mi Notebook Air 13.3" 2018

MacOS Versions Supported:

• macOS 10.15 Catalina

What do I need?

• Xiaomi Notebook Air 2018 13.3" i5-8250u / i7-8550u (2017 model and 2019 model with MX250 also reported to be working)
• macOS or windows PC to create the install USB
• 8GB or larger USB stick (USB3 preferred for speed)
• Latest copy of these files (https://github.com/johnnync13/Xiaomi-Mi-Air/releases)
• (optional for multiboot) Second (M.2 SATA) SSD installed inside the laptop.
• (possibly) USB mouse for install until trackpad is working
• (possibly) For macOS 10.15: a natively supported (e.g. Apple) USB Ethernet adapter for installation (Apple / Amazon / Ebay)
• (possibly) If you have an android phone, you can tether wifi from it using the Tools/HoRNDIS.kext. Put it on a USB stick, load it in the recovery terminal/Terminal.app using kextload and connect your phone via cable, e.g. (replace 'USB' with your usb stick name):

sudo kextload -v /Volumes/USB/HoRNDIS.kext

• (possibly) If your laptop came with a PM981 SSD, consider replacing it with a different one (Google Hackintosh compatibility) or install macOS on a separate (M.2 SATA) SSD. There's known issues with the PM981 and macOS. This is currently 'fixed' with the NVMeFix kext.

What is Working?

• Native CPU Power Management
• Sleep/Wake
• Intel Graphics
• Audio (AppleALC)
• Trackpad (gestures)
• HDMI Video and Audio
• USB 3.0
• NVMe / SATA SSD's
• Battery Management
• Brightness keys
• Built-in camera
• Built-in mic
• FileVault Disk encryption (Always make a backup before switching on!!!)

Half working:

• Wifi Intel Is stable now. Only implemented 11n stack but in the future 11ac y 11ax will be implemented. You only need install HeliPort app.
• Bluetooth Intel (no Airdrop, Handoff or Continuity on Intel BT) **Caution: Intel Bluetooth kexts can cause frequent kernel panics / crashes when using sleep/wake. This now is fixed on the last version kext

Not working:

• Nvidia GPU (MX150/GP108) (Not supported under macOS and probably never will be)
• Fingerprint Sensor (may be possible using libfprint in the future see #94)

Installation

Sounds good! Where do we start? You need a computer with macOS or Windows (scroll down)

Clover or OpenCore?

First let's figure out if we would like to use Clover or OpenCore. The pro's / con's listed:

Clover

Pro's (+)

• Most used, best supported online
• Easy to configure with Clover Configurator

Con's (-)

• Might be less compatible with macOS updates in the future
• Less secure (csr 67 flag needed to inject kext drivers, SIP, the macOS security system, is off)
• Need to put kext files in /Library/Extensions/

OpenCore

Pro's (+)

• Most secure (no csr 67 flag, SIP, the macOS security system, stays on)
• Most compatible with future upgrades of macOS
• No need to put kext files in /Library/Extensions/, therefore 'vanilla' macOS install
• Faster than Clover

Con's (-)

• Complex to customise (Useful tool to edit config: https://github.com/corpnewt/ProperTree)
• (Use with caution) Unnofficial OpenCore Configurator
• Without Theme UI until release. (Beta UI now included in this repo)

Installing from macOS:

Clover method:

• On your mac, create your macOS USB install media (e.g. https://support.apple.com/en-us/HT201372)
• Mount the ESP (EFI System Partition) on your USB stick: (check that you mount the correct EFI partition, numbers will vary!!!)

diskutil list
sudo diskutil mount /dev/disk3s1

• Copy and overwrite the contents of the EFI folder on your USB stick with the contents of the EFI folder from this website.
• Eject the USB stick from your computer and insert in the Xiaomi laptop.
• Now boot the Xiaomi laptop from the install media (if trackpad is not working, use USB mouse. If network connection needed, use a Apple compatible USB Ethernet adapter)
• Open Disk Utility and format the builtin SSD or second SSD with APFS (will delete all your files!!!)
• Install macOS
• After install, boot from USB again but select SSD to boot from in the Clover Bootloader
• Do initial macOS setup (use USB Ethernet adapter for internet)
• Mount the ESP (EFI System Partition) on your SSD (check that you mount the correct EFI partition, numbers will vary!!!)

diskutil list
sudo diskutil mount /dev/disk0s1

• Copy and overwrite the contents of the EFI folder from this website to the EFI folder on the ESP on your SSD.
• Copy all the Kernel Extensions (kexts) from the EFI/CLOVER/kexts/Other to your system's /Library/Extensions folder (this is important, otherwise keyboard/trackpad and other devices might not work)
• Execute these commands in Terminal to rebuild Kernel Extension Cache:

sudo chmod -R 755 /System/Library/Extensions/
sudo chown -R root:wheel /System/Library/Extensions/
sudo chmod -R 755 /Library/Extensions/
sudo chown -R root:wheel /Library/Extensions/
sudo touch /System/Library/Extensions/
sudo touch /Library/Extensions/
sudo kextcache -i / && sudo kextcache -u /

• Remove the USB stick from the laptop
• Done! Reboot to enable all the kexts. Enjoy your Hackintosh!

OpenCore method:

• On your mac, create your macOS USB install media (e.g. https://support.apple.com/en-us/HT201372)
• Mount the ESP (EFI System Partition) on your USB stick: (check that you mount the correct EFI partition, numbers will vary!!!)

diskutil list
sudo diskutil mount /dev/disk3s1

• Copy and overwrite the contents of the EFI folder on your USB stick with the contents of the EFIOC (opencore) folder from this website.
• Eject the USB stick from your computer and insert in the Xiaomi laptop.
• Now boot the Xiaomi laptop from the install media (if trackpad is not working, use USB mouse. If network connection needed, use a Apple compatible USB Ethernet adapter)
• Open Disk Utility and format the builtin SSD or second SSD with APFS (will delete all your files!!!)
• Install macOS
• After install, boot from USB again but select SSD to boot from in the OpenCore Bootloader
• Do initial macOS setup (use USB Ethernet adapter for internet)
• Mount the ESP (EFI System Partition) on your SSD (check that you mount the correct EFI partition, numbers will vary!!!)

diskutil list
sudo diskutil mount /dev/disk0s1

• Copy and overwrite the contents of the EFIOC (opencore) folder from this website to the EFI folder on the ESP on your SSD.
• Remove the USB stick from the laptop
• Done! Reboot and enjoy macOS.

NOTE

• It is somewhat important on OpenCore that the laptop have unlocked CFG Lock. Your laptop will work without, but doing the mod results in better CPU power management, sleep/wake and overall better behaviour like a mac. It is very easy on most laptops because the BIOS has an option in the menu. But on Xiaomi Laptops, the BIOS is locked. Read more about it here.

From Windows:

Clover method:

Downloading macOS:

macOS is working! Next steps:

(optional) Fixing iMessage, FaceTime etc.

This can be a bit of a challenge, and outside of the scope of this repo, but if you want to, have a look here:
An iDiot's Guide To iMessage (clover)
Fixing iServices (OpenCore)

(optional) WiFi

Still very buggy, but improving fast. Have a look here

If your Intel Wifi not working, please be patient, the driver is getting better really fast. Until then, use a macOS compatible USB Wifi dongle or Ethernet adapter.

(optional) Garbled Audio Problems

If you're having audio problems, especially with headphones, read more about it under Audio

(optional) Display Color Profile:

Troubleshooting

I have a problem an don't know what to do!

Please read the issues section, and only if your question is not yet answered, submit a new one.

Some device in my system is not working under macOS!

Using Clover:

• Make sure all kexts are in /Library/Extensions/ then run:

sudo chmod -R 755 /System/Library/Extensions/
sudo chown -R root:wheel /System/Library/Extensions/
sudo chmod -R 755 /Library/Extensions/
sudo chown -R root:wheel /Library/Extensions/
sudo touch /System/Library/Extensions/
sudo touch /Library/Extensions/
sudo kextcache -i / && sudo kextcache -u /

• Reboot.

Using OpenCore:

• Make sure the kexts are in the EFI/OC/kexts folder on your SSD EFI system partition (ESP).
• Reboot. If still not working, try resetting the NVRAM from OpenCore boot menu.
