Asus-K53SC-OpenCore

(based on dubsteptwo’s EFI)

Note

This EFI is based for macOS 10.13

Prerequisites

• The same exact laptop
• 2 GB+ flash drive (fast one is recommended)
• Windows 10 and up (maybe Windows 8 / 8.1 will work with Python 3, idk)
• Python 3 (>=3.9)
• Some knowlege of what you’re doing

What changed

• Model (from MacBookAir6,1 “Haswell” to ‘MacBookPro8,1 “Sandy Bridge”) - fixes graphics after 10.13
• USB 2 & 3 support
• Added NullCPUPowerManagement.kext, won’t boot without it

What doesn’t work (still)

• Webcam

Download

Latest (v1.0.7) | v1.0.6 | v1.0.3 (debug)

How to make it work

Download macOS 10.13 with macrecovery using either:

py macrecovery.py -b Mac-7BA5B2D9E42DDD94 -m 00000000000J80300 download

py macrecovery.py -b Mac-BE088AF8C5EB4FA2 -m 00000000000J80300 download

You need to:

• Format the flash drive (2GB in FAT32 - works the best)
• Put the files in there (EFI and com.apple.recovery.boot on the root of the drive)
• Set up SMBIOS (just for it to be different)

Or follow the guide: https://dortania.github.io/OpenCore-Install-Guide

Recommended to remap USB via USBToolBox:

1. Go to “C. Change Settings” -> enable both Native Classes and Legacy Native Classes (N and L), then B to get back
2. Go to “D. Discovr Ports” -> connect any USB device to every USB port, then B to get back
3. Go to “S. Select Ports And Build Kext” -> K. Build Kext -> enter “MacBookPro8,1”
4. Copy the USBMapLegacy.kext folder to “Kexts” foldr in OC

Recommended to regenerate SMBIOS info:

1. Open GenSMBIOS, then “2. Select config.plist”
2. Drag and drop config.plist, then Enter
3. “3. Generate SMBIOS” -> input “MacBookPro8,1”, tthen Enter. It’ll automatically put the info in config.plist

Make sure you have enabled UEFI Boot in the BIOS

The Recovery Server Could Not Be Contacted

For this, go to Utilities -> Terminal, and type / paste this:

nvram IASUCatalogURL="http://swscan.apple.com/content/catalogs/others/index-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog"

How to make it boot from the hard drive

1. Install a linux distro of your choice (in this ex. Ubuntu) in UEFI mode, so it creates an NVRAM entry
2. Navigate to the EFI partition, then EFI/BOOT, and change BOOTx64.efi to the one in the OpenCore EFI folder
3. Go to EFI/ubuntu, and delete ‘grubx64.efi’, copy the BOOTx64.efi, and rename it to ‘grubx64.efi’

If it doesn’t use GRUB as a bootloader, change all .efi files in BOOT and the 2nd folder (if present) to the exact names in the folder
