Not work (IDK how to fix it):

Bluetooth ❌ (Don't use any Bluetooth Kext for fix, causes Kernel panics)

Card Reader ❌ (ACPI Problems)

Installation Method:

Before to try it:

Maybe you need a External Keyboard and Mouse for use, and evite use USB 3.0/3.1 for Bootable USB Drive.

Using any macOS BigSur (or Monterrey Beta) Image based on Olarila project and Balena Ecther for doing Booteable USB Drive.
If macOS image won't boot, mount Booteable USB Drive ESP (EFI) partition with ESP Mounter Pro or Clover/OpenCore Configurator (MacOS) or MiniTool Partition (Windows) and replace EFI Folder with THIS repo EFI Folder.
Boot to USB Drive always with BIOS Secure Boot ENABLED (if you disable Secure Boot, MacOS Preinstalled on Hard Drive/Solid Drive never will boot, stuck on Apple logo).

Post-Installation：

WARNING ⚠️ : If you wanna have Dualboot with Windows or Linux, Touchpad may be don't work, OpenCore EFI modify some ACPI values (Advanced Configuration and Power Interface, a.k.a. memory access & Power from BIOS/Chipset to peripherics and motherboard components) and Touchpad (Synaptics or Elantech) crash with these modifies.

Mount the macOS Drive EFI Partition (with ESP Mounter Pro), later, drag EFI Folder from Booteable USB Drive and reboot.
Now, when you boot from your macOS Drive, go to Extras folder and run "GenSMBIOS.command", select option 2 for select included config.plist, after, select option 3 for generate a new Apple SMBIOS and Serial. This is for fix not working Apple ID and Apple Aplications.
If you have any Intel Wi-Fi card mentioned above, move and open "HeliPort" and configurate for enable in Autostart (System Preferences), Network connection aren't the best, but works.

Applications Support:

Warning: Some Apple apps as iMessage, FaceTime, App Store, Apple Music and etc won't login although you have patched SMBIOS before, you need an Apple product serial compatible with Apple Support too, consult in Olarila how fix it.

EDIT: Now some Apple Apps were patched to work.

Developer	App(s)
Apple	Store, iMesssage/FaceTime (partially), Mail, Maps, Music...
Adobe	Photoshop, Lightroom, Premiere Pro, Audition, Illustrator, Acrobat DC, After Effects, XD, InDesign, etc. (2019, 20 & 21 versions)
Electronic Arts	Origin, The Sims 4, Battlefield 1 and V (worse performance than Windows).
Microsoft	Office Suite, Teams, Edge.
Blackmagic	Davinci Resolve (17.x)
TechSmith	Camtasia Studio (latest version)
Valve	Steam (IDK if Proton is included)
Facebook	Facebook, Whatsapp, Instagram, etc.
Adobe(x2)	Dreamweaver (not working)

Misc:

Some additional drivers and SSDTs are imported from Dell i7 5500U EFI Laptops, enable for backlight and some keyboard controls, could be some Fn commands doesn't work correctly, for example: Brightness control works pressing "Pause" (for up backlit) or "Lock Scroll" (for down Backlit).
