Hackintosh Big Sur guide for the Acer E5-575-50RM.

IMPORTANT Hackintosh Build is not 1/2 hour work it requires you to research about your hardware and its compatibility. Start this project only when you have ample amount of time and patience

Specs

1. Intel i5-7200U(kabylake)
2. RAM: 8 GB(Single stick)
3. IGPU: Intel UHD 620 (No dedicated 2GB Nvidia 940mx available in this variant)
4. Audio: Realtek ALC 255 (layout id: 3)
5. I2C touchpad with native apple gestures supported (Enable "Advanced" in touchpad section in BIOS).

Step 1: Downloading MAC OS BIG SUR

• Follow this Guide to download the MacOS, follow that guide only upto downloading part. For setting up of EFI files refer to this guide.

Step 2: Gathering Files

• Make a new folder ACPI and download these files and place it there

  • SSDT-PLUG
  • SSDT-EC-USBX
  • SSDT-XOSI
  • SSDT-PNLF

• Now make a folder Kexts and download these files and place it there

  • Lilu
  • WhateverGreen
  • VirtualSMC //Copy everything except SMC Dell sensors.kext and SMC light sensors.kext
  • VoodooPS2Controller
  • Voodoo I2C //for gesture support
  • Apple ALC //for audio
  • USBInjectAll //sometimes usb ports doesn't work so this is required sometimes

Step 3: Combining Files

• Now download Latest opencore release.
• Extract the zip file and copy EFI folder from X64 to any convenient place.
• Head to OC folder and there in ACPI folder, paste all the files we downloaded and placed in our ACPI folder.
• Now in OC folder, head to Drivers and delete everything except HfsPlus.efi and OpenRuntime.efi
• Again in OC folder, head to kexts folder and paste all the files we downloaded in our kexts folder.
• Now in Resources folder delete everything but keep the folder.
• Same goes for Tools folder.

Step 4: Editing Config.plist

• I have provided a sample plist so you can edit that or use the sample plist provided in opencore release docs. It's upto you.
• You need to download two files
  • ProperTree
  • GenSMBIOS
• Use GenSMBIOS to generate your serial number. Remember while generating serial keys use MacBookPro 14,1 as it is most compatible with this system.
• Now download the config.plist file given here. and place it in OC folder.
• Now Launch ProperTree and open config the plist you just copied to EFI/OC/
• Go to file->OC Snapshot and select EFI/OC/
• Now expand ACPI section and go to the section where it says SSDT_XOSI.AML. This is required for native apple gestures support. Check if following values are there or not. if not add them. For people editing sample plist from opencore docs you can also add this:

Comment	String	Change _OSI to XOSI
Count	Number	0
Limit	Number	0
Find	Data	5F4F5349
Replace	Data	584F5349

• Now head over to Device properties->Add.
• Check if present or not:

PciRoot(0x0)/Pci(0x1b,0x0)	Dictionary	1 key/value pair

• and under this, check if this is present or not:

device-id	Data	16590000

• if not present add them as it is necessary for Intel UHD 620 graphics to work.
• Now head over to PlatformInfo -> Generic
  • In SystemProductname add MacBookPro 14,1.
  • In SystemSerialNumber add serial number you generated from GenSMBIOS
  • In In SystemUUID add SmUUID value
  • In MLB add Board Serial Value
• Save the Config.plist file
• To check if something is missing head over to sanity checker
• Your EFI file is ready, now if you have followed the guide carefully then you must have your MacOS ready to install. IMPORTANT: YOU NEED TO CLEAN FLASH THE MAC OS i.e. YOU NEED TO FORMAT YOUR SSD/HDD WHILE INSTALLING MAC OS SO MAKE SURE YOU HAVE BACKED UP YOUR FILES

BIOS OPTIONS

• Make sure secure boot is turned off and F12 boot is enabled Post Installation Guide
• Install open core configurator and mount EFI partiton on your device and copy EFI files from your USB to your laptop EFI partition.
• Dont bother fixing imessages and facetime. Every apple services except these works.
