🖼 Screenshots

macOS 10.13.6 (High Sierra)	macOS 12.7.6 (Monterey)
macOS 14.8 (Sonoma)	macOS 15.7 (Sequoia)

🔧 Installation Notes

1. This is a legacy system → you must create your own boot file (USB + internal EFI).

   • Windows: Legacy Setup - DiskPart Method
   • macOS: Legacy Setup

2. Nvidia Tesla GPU:

   • Follow Legacy Nvidia Patching Guide before installing macOS, using ROM from the Requirements section.

3. NVRAM doesn't work, you will have to emulate it, see NVRAM Emulation with nvram.plist.

🖥 SMBIOS

⚠️ SMBIOS in this repo is only sample.
Generate your own using GenSMBIOS.

• Use unused / invalid SMBIOS.
• Needed only for iServices.

🍏 macOS Compatibility

Version	Status	Notes
High Sierra	✅ Works	Hardware "officially" supported
Big Sur and newer	⚠️ Requires patching	Needs OCLP patches for non-Metal acceleration
Ventura and newer	⚠️ Requires PCI enumeration quirk	Otherwise stalls with IOPCIConfigurator::configure kIOPCIEnumerationWaitTime is 900

📝 System Notes

See issues/workarounds: OCLP Issue #108 for macOS 11+!

High Sierra - Catalina (10.13.x - 10.15.x):

• Works with Intel WiFi when SecureBootModel is set to j137.
• Troubleshooting: Apple Secure Boot special notes

Note: For macOS 10.14+, use telemetrytrap kext to patch missing SSE4.2:

• Add telemetrytrap kext.

Big Sur (11.x):

Steps to prepare with config.plist:

1. Use telemetrytrap kext to patch missing SSE4.2:

• Add telemetrytrap kext,

2. Use AMFIPass to bypass disabling AMFI for root patching:

• Add AMFIPass kext,

3. Set SIP to 0x803:

• NVRAM → Add → 7C436110-AB2A-4BBB-A880-FE41995C9F82 → csr-active-config → 03080000,

4. Disable Apple Secure Boot:

• Misc → Security → SecureBootModel → Disable,

5. Disable Signed DMGs loading:

• Misc → Security → DmgLoading → Any,

6. Reset NVRAM

• Using ResetNvramEntry.efi in EFI/OC/DRIVERS.

7. In Recovery:

   csrutil disable --no-internal
   csrutil authenticated-root disable

8. Run latest OCLP

Monterey (12.x):

Steps to prepare with config.plist:

1. Follow Big Sur steps (1-6),

2. Patch AVX1 in CompressionTypeZlib for macOS 12.4+:

• Add NoAVXFSCompressionTypeZlib kext,

3. Run latest OCLP (>= 0.4.5).

Ventura and newer

Currently unstable, gets stuck at IOPCIConfigurator::configure kIOPCIEnumerationWaitTime is 900.

FIXED: Requires PCI Enumeration (Kernel → Patch quirk) in config.plist to fix the issue.

Ventura (13.x, OCLP 0.6.0+)

Steps to prepare with config.plist:

1. Follow Big Sur steps (1-6),

2. Set SMBIOS → MacBookPro14,x:

• Use GenSMBIOS,

3. Patch AVX1 in FSCompressionTypeZlib for macOS 13+:

• Remove/Disable/Set MaxKernel to 21.99.99 for NoAVXFSCompressionTypeZlib kext,
• Add NoAVXFSCompressionTypeZlib-AVXpel, setting MinKernel to 22.00.00,

4. Use Rosetta 2 Cryptex to patch AVX2 for macOS 13+:

• Add CryptexFixup kext, setting MinKernel to 22.00.00,

5. Use RSRHelper to handle Rapid Security Response updates for macOS 13.3+:

• Add RSRHelper kext, setting MinKernel to 22.00.00,

6. Resolve removed AppleIntelCPUPowerManagement in macOS 13+:

• Enable DummyPowerManagement quirk:
  • Kernel → Emulate → DummyPowerManagement → True,
• Add AppleIntelCPUPowerManagement and AppleIntelCPUPowerManagementClient kexts, setting MinKernel to 22.00.00,

7. Fix PCI Enumeration stall (Kernel → Patch quirk), setting as follows (Ventura only):

   Key	Type	Value
   Arch	String	x86_64
   Base	String	__ZN17IOPCIBridge0HotplugPortEP16IOPCIConfigEntry
   Comment	String	Fix PCI bus enumeration (Ventura)

   ReplaceMask	Data
   Skip	Number	0

8. In Recovery:

   csrutil disable --no-internal
   csrutil authenticated-root disable

9. Run latest OCLP (>= 0.6.0).

Sonoma (OCLP 1.0.0+)

1. Follow Big Sur steps (1-6),
2. Set SMBIOS → MacBookPro15,x:

• Use GenSMBIOS,

3. Use Intel WiFi kext compatible with Sonoma,

4. Fix PCI Enumeration stall (Kernel → Patch quirk), setting as follows (Sonoma+):

   Key	Type	Value
   Arch	String	x86_64
   Base	String	__ZN17IOPCIConfigurator18IOPCIIsHotplugPortEP16IOPCIConfigEntry

   Skip	Number	0

5. In Recovery:

   csrutil disable --no-internal
   csrutil authenticated-root disable

6. Run latest OCLP (>= 1.0.0).

Sequoia (OCLP 2.0.0+)

1. Follow Big Sur steps (1-6) and Sonoma steps (1-5),
2. ⚠️ No Intel WiFi kexts (without root patching) → Ethernet only

• Remove Airportitlwm.kext from EFI/OC/KEXTS,
• Make sure to use BCM5722D kext for Ethernet!

3. (Optional/Post Install) Spoofing Intel WiFi and patching with OCLP:

• Add following kexts to EFI/OC/KEXTS and set MinKernel to 24.0.0 for each:

  • Airportitlwm.kext (v2.3.0 for Ventura),
  • IOSkywalkFamily.kext,
  • IO80211FamilyLegacy.kext,
  • IO80211FamilyLegacy.kext/Contents/PlugIns/AirPortBrcmNIC.kext.

• Using Hackintool, go to PCIe tab, find your Intel WiFi → Copy DevicePath,

• Open config.plist with ProperTree,

• Add your Intel WiFi card: DeviceProperties → Add → PciRoot(0x0)/Pci(0x1F,0x3) (example, use your own path),

• Spoof your Intel WiFi card:

  Key	Type	Value
  IOName	String	pci14e4,43a0
  compatible	String	pci106b,117
  device-id	Data	A0430000
  device_type	String	Network Controller
  model	String	BCM4360 802.11ac Wireless Network Adapter
  name	String	pci14e4,43a0
  pci-aspm-default	Number	0
  subsystem-id	Data	17010000
  subsystem-vendor-id	Data	6B100000
  vendor-id	Data	E4140000

• Enable Kernel → Block → Allow IOSkywalk Downgrade, make sure MinKernel is set to 24.0.0 for Sequoia:

  Identifier	Comment	Enabled	Strategy	MinKernel	MaxKernel	Arch
  com.apple.iokit.IOSkywalkFamily	Allow IOSkywalk Downgrade	true	Exclude	24.0.0		x86_64

4. Run latest OCLP (>= 2.0.0),

5. (Optional, if you did spoofing) After root-patching with OCLP, comment out (by adding #) your Intel WiFi card in DeviceProperties to make it work normally:

• EFI/OC/config.plist → DeviceProperties → Add → #PciRoot(0x0)/Pci(0x1F,0x3) (example, use your own path).

6. Finally, reboot and enjoy Intel WiFi on Sequoia!

NOTE: You will need to repeat the spoofing, patching and commenting out steps after every macOS update.

✅ What’s Working

1. Intel WiFi:

• High Sierra with j137 SBM,
• Up to Sonoma with with proper kext,
• Sequoia requires temportary spoofing and patching (Annoying but works).

2. Broadcom Ethernet,
3. USB ports
4. CD/DVD drive
5. iServices (with proper SMBIOS)

⚠️ Partially Working

• Trackpad (feels too sensitive, use USB mouse).

❌ What’s Not Working

• Bluetooth (it's BCM2046, but mine seems dead),
• Audio (ALC888, no supported layout-id found),
• SD card slot,
• Fan monitoring,
• Sleep / Hibernation,
• Shutdown (macOS will shut down but the laptop will stay on).
