Read the following documentation carefully in order to install/boot macOS successfully! ### Before you begin ⚠️ The built-in Samsung PM981a NVMe that comes with the system is NOT compatible with macOS. You _must_ use a different NVMe! ### Notable Features - [x] Compatible with macOS Sonoma and Sequoia (works with older versions of macOS as well, but requires different WiFi-Kexts and config adjustments) - [x] Woorking Thunderbolt 3 over USB-C - [x] New USB Port Mapping with support for docking station - [x] Optimized Framebuffer Patch for smoother handshake with external displays via HDMI - [x] Working clamshell mode (when connected to A/C and external display) - [x] Working MicroSD Card Reader - [x] Working 3D globe in Maps app (macOS 12+) - [x] No injection of `PlatformInfo` data into Microsoft Windows. - [x] YogaSMC support for additional features like CPU fan control, performance bias, handling Fn Keyboard shortcuts, additional OSD overlays, etc. - [x] Lean EFI folder with slimmed kexts (20 MB instead of 62 MB overall): - **AirportItlwm_Sonoma**: 1,8 instead of 16 MB. Only contains Firmware for Intel AC 9560. - **AppleALC**: 86 Kb instead of 2,3 MB. Only contains layout `97`. - **IntelBluetoothFirmware**: 560 KB instead of 11,5 MB. - **itlwm** (1.5 mb instead of 16 mb). Only Contains Firmware for Intel AC 9560. ### Known Issues - [ ] Hibernation Mode 25 does not work properly - [ ] Fingerprint sensor does not work under macOS since there is currently no way to emulate Touch ID. - [ ] The audio combo jack creates an unpleasant buzz/noise during driver initialization. So it's best to connect headphones *after* booting. > [!IMPORTANT] > > - Before reporting any issues, ensure that your system uses the latest available UEFI and EC Firmware. > - Don't install macOS on an external disk or flash drive – use a compatible internal disk. ### Future Developments - [x] Adding USB ports of docking station to the USB port kext - [ ] Creating an AppleALC Layout-ID for audio output on Docking Station - [x] Adjusting Framebuffer Patch so HDMI/DP Ports on docking stations can be utilized ## System Specs Category | Description :-------:|------------ **Model** | Lenovo ThinkPad T490 **Variant** | [**20N3**](https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t490-type-20n2-20n3/document-userguide) **BIOS** | **UEFI**: v1.83 (2024-06-20)

## Preparations ### Config Adjustments - Download the [**latest Release**](https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/releases/latest) of my EFI folder and unzip it - Open the `config.plist` with a plist editor (e.g. ProperTree or OCAT) and adjust the following settings based on the used version of macOS and personal preferences: - **Graphics** - `Devices/Properties/Add/PciRoot(0x0)/Pci(0x2,0x0)` - For macOS ≤ 13.3, disable/delete `enable-backlight-registers-alternative-fix` and use `enable-backlight-registers-fix` instead to fix black screen issues. - If other issues occur, try another framebuffer patch. I collected addtitional ones which be found [here](https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/blob/main/Additional_Files/Framebuffer_Patches/UHD620_Framebuffer_Patches.plist) - **Wi-Fi**: Decide, which Wi-Fi kext you want to use (→ see [**AirportItlwm vs. itlwm**](#airportitlwmkext-vs-itlwmkext)): - By default, Sonoma uses **AirportItlwm_Sonoma** - By default, Sequoia *requires* **Itlwm**. But with the help of OpenCore Legacy Patcher, **AirportItlwm** can be used as well. And that's what I configured my config for. - **Kernel/Quirks** - `AppleXcpmCfgLock` is not required on my system. Try for yourself if your T490 needs it to boot. - **NVRAM/Add/7C436110-AB2A-4BBB-A880-FE41995C9F82** - Optional: add `boot-args` `-v`, `debug=0x100` and `keepsyms=1` for debugging if you face issues. - **UEFI/APFS** - Change `MinVersion` and `MinDate` to `-1` if you want to run macOS Catalina or older. - **Platforminfo/Generic**: SMBIOS - Generate `MLB`, `Serial` and `ROM` for `MacBookPro15,2` using GenSMBIOS or OCAT. - Save the changes > [!CAUTION] > > - Don't change the SMBIOS or the USB port mapping injected by `USBMap.kext` won't be applied and Bluetooth won't work either! If you change the SMBIOS, then you also need to change the `model` property in the `info.plist` contained in the kext to match the selected SMBIOS ([instructions](https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/issues/13#issuecomment-1858917249)). > - If your T490 model uses a different WiFi/BT card than the stock Intel AC-9560 card, use the official `itlwm.kext` instead because mine only contains the firmware for the AC-9560, so it won't work with other cards. ### AirportItlwm vs. itlwm WiFi kext Although the Intel AC-9560 Card is compatible with both kexts (use either one or the other), there are Pros and Cons to both of them (check the [**FAQs**](https://openintelwireless.github.io/itlwm/FAQ.html#features) for other differences): - **AirportItlwm**: (used in macOS Sonoma, requires root patches in Sequoa) - **Pro**: Can be used during macOS Setup/Recovery which is not possible with `itlwm.kext` - **Pro**: Supports Location Services and "Find My Mac" - **Pro**: Connects faster to Wi-Fi Hotspots than `itlwm.kext` - **Con**: Doesn't perform as well as `itlwm.kext` - **Con**: Can't connect to hidden WiFi Networks - **Con**: Requires the correct kext per macOS version, so running multiple version of macOS requires multiple versions of this kext controlled via `MinKernel` and `MaxKernel` settings - **Con**: iMessage and FaceTime don't work when using AirportItlwm (→ See [Issue 14](https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/issues/14)) - **itlwm.kext** (used in macOS Tahoe) - **Pro**: `itlwm.kext` works across _multiple_ versions of macOS - **Pro**: Loading webpages feels a lot quicker than with `AirportItlwm` - **Pro**: Can connect to hidden WiFi Networks - **Pro**: Does work with iMessage and FaceTime - **Con**: Requires [**HeliPort**](https://github.com/diepeterpan/HeliPort/releases) app to connect to Wi-Fi hotspots, so it can't be used during macOS Setup/Recovery - **Con**: Doesn't support Location Services - Pre-compiled WiFi kexts for other versions of macOS can be found in the [Additional Files](https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/tree/main/Additional_Files/Slimmed_Kexts/Intel_AC-9650/itlwm) section! You will need them if you want to run older versions of macOS! > [!NOTE] > > My config uses `AirportItlw` by default since it allows accessing the internet during macOS installation (unlike `itlwm.kext`, which requires an additional app to do so). Currently, `AirportItlwm` kexts for macOS Sonoma and Sequoia are included, while macOS Tahoe requires `itlwm.kext`. > > If you want to use `itlwm`, disable `AirportItlwm` (all variants), enable `itlwm` and adjust the `MinKernel` setting to match the Kernel version of macOS (currently: 24.0.0 = macOS Sequoia). Next, download the [**HeliPort**](https://github.com/OpenIntelWireless/HeliPort) app, run it and add it to "Login Items" (in System Settings), so that it starts automatically with macOS. ## Deployment ### If macOS is installed already - Put the EFI folder on a FAT32 formatted USB flash drive - Reboot from said USB flash drive for testing - If it works, mount your system's ESP, replace the BOOT and OC folders in the EFI folder - Continue with Post-Install ### If macOS is not installed - Follow Dortania's [**OpenCore Install Guide**](https://dortania.github.io/OpenCore-Install-Guide/installer-guide/#making-the-installer) to prepare a USB Installer - **Optional**: Once the USB has been created, download the latest version of [**HeliPort**](https://github.com/diepeterpan/HeliPort/releases) and copy the .dmg to your USB Installer (only required when `itlwm.kext` is used for Wi-Fi) - Next, mount the ESP of the USB Installer (you can use [**MountEFI**](https://github.com/corpnewt/MountEFI) for this) - Put the EFI folder on the EFI partition of the USB installer - Reboot from the USB installer - Install macOS - Once that is completed, continue with Post-Install > [!CAUTION] > > Upgrading from to macOS 14.3.1 to 14.4 or newer via `System Update` causes a Kernel Panic during install! Disable `AiportItlwm` and enable `itlwm.kext` instead. Set `SecureBootModel` to `Disabled`, reset NVRAM and run the update again. If this does not work, use this [workaround](https://github.com/5T33Z0/OC-Little-Translated/blob/main/W_Workarounds/macOS14.4.md) to install macOS 14.4 on a new APFS volume. Use Migration Manager afterwards to get your data onto the new volume! ## Post-Install ### Disable Gatekeeper (optional) Gatekeeper can be really annoying and wants to stop you from running python scripts from github, etc. Do the following to disable it: - Open Terminal and run: `sudo spctl --master-disable` - The process has slightly changed in macOS Sequoia 15.1.1. and newer [more info](https://github.com/5T33Z0/OC-Little-Translated/blob/main/14_OCLP_Wintel/Guides/Disable_Gatekeeper.md) ### Fixing On-Board Audio with OCLP Mod (macOS Tahoe beta 2) Apple deleted the AppleHDA required for on-board audio in macOS 26 beta 2. Since there's no official OCLP version available for macOS Tahoe yet, we are going to use [**OCLP Mod**](https://github.com/laobamac/OCLP-Mod/) to apply root patches – which will also install AppleHDA, thereby re-enabling audio. (→ [Instructions](https://github.com/5T33Z0/OCLP4Hackintosh/blob/main/Enable_Features/Audio_Tahoe.md#instructions)) ### WiFi #### Option 1: enable `AirportItlwm.kext` in macOS Sequoia By default, `Itlwm.kext` is requird when running macOS 15. But if you want to use `AirportItlwm.kext` instead, you have to apply "Modern WiFi" patches with OpenCore Legacy patcher: - Download [**OpenCore Legacy Patcher**](https://github.com/dortania/OpenCore-Legacy-Patcher/releases) (.pkg). - Remove `HeliPort` from Login-Items (if present) – you won't need it any more. - Download my EFI folder and extract it. - Place it in your EFI partition. - Reboot - Reset NVRAM - Boot into macOS Sequoia - At this stage, WiFi won't work! - Install OpenCore legacy patcher and run it - Click on "Root Patches" - Next, click on "Start Root Patching" to install the required frameworks for "Modern Wi-Fi" - Once that's done, reboot - Reset NVRAM and start macOS Sequoia. - Connect to a WiFi AP via Airport-Utility More details about this patch can be found [here](https://github.com/5T33Z0/OC-Little-Translated/blob/main/14_OCLP_Wintel/Enable_Features/AirportItllwm_Sequoia.md) #### Option 2: For `Itlwm.kext` users - Mount **HeliPort.dmg**, drag the app into the "Programs" folder and run it. - Use it to connect to your WiFI hotspot. - Add HeliPort to "Login Items", so it stars with macOS and connects to your WiFi network automatically. ### Enable YogaSMC (optional, not recommended) Starting with Release 1.0.5 v1.0 of my OC EFI folder, I've disabled YogaSMC, CPUFriend and the required SSDTs due to reported [CPU performance issues](https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/issues/44#issuecomment-2798489637). You can still re-enable it if you want to but I won't support it. - **Config Settings**: - Enable `SSDT-ECRW.aml`, `SSDT-THINK.aml` and `YogaSMC.kext` - Disable `SSDT-T490-KBRD.aml` and ACPI patches for the Keyboard Shortcuts - Download [**YogaSMC-App**](https://github.com/zhen-zen/YogaSMC/files/14324664/Builds.zip) and mount it. This is a custom build which fixes the "Failed to open Preferences" [issue](https://github.com/zhen-zen/YogaSMC/issues/189) in Ventura and newer - Double-click the YogaSMC **prefPane** to install it - Drag the `YogaSMC` app into the "Programs" folder and run it - Click on the icon (⌥) in the menu bar and select "Start at Login" - Now you can control performance profiles, fan speed and other settings ### Configure CPUFriend - Use [**CPUFriendFriend**](https://github.com/corpnewt/CPUFriendFriend) to generate your own `CPUFriendDataProvider.kext` to optimize CPU Power Management if your T490 uses a different CPU than mine. ### Configure Hibernation - Disable PowerNap: `sudo pmset -a powernap 0` - Change Hibernatemode to 3: `sudo pmset -a hibernatemode 3` - For more details, have a look at my [Hibernation Configuration Guide](https://github.com/5T33Z0/OC-Little-Translated/blob/main/04_Fixing_Sleep_and_Wake_Issues/Changing_Hibernation_Modes/README.md) > [!IMPORTANT] > > Currently, Hibernatemode 25 does not work properly since I haven't figured out completely which RTC memory regions to block. I've managed to skip RTC memory checksum errors and restore the system from the sleepimage but it freezes after returning to the desktop after 2 seconds (scrambled image). Any assistence for fixing this would be highly appreciated. ### Install MonitorControl (optional) [**MonitorControl**](https://github.com/MonitorControl/MonitorControl) is a helpful little tool that lets you control the brightness and contrast of external displays from the menubar. ## Understanding YogaSMC Settings Open the YogaSMC preference pane. You will find the following options (among others): - `DYTC`: DYTC stands for `Dynamic Thermal Control`. It allows the OS or firmware to manage the thermal characteristics of a device or component dynamically, adjusting power and performance to maintain safe operating temperatures. 3 profiles are available: "Quiet", "Balanced", and "Performance" - If you tick the `PSC support`, the control for the slider becomes more nuanced. Instead of 3 positions it gets more increments. I think `PSC` refers to `Power State Current` in the `DSDT` and is used to control different levels of performance via the slider. ### Disabling YogaSMC If you don't want to use YogaSMC, do the following: - In macOS: - Open System Preferences - Right-Click on `YogaSMCPane` and remove it - Under "Login items" (or similar) remove the YogaSMC App from the list - Config.plist: - Under `ACPI`, disable `SSDT-THINK.aml` and `SSDT-ECRW.aml` - Under `Kernel`, disable `YogaSMC.kext` > [!NOTE] > > After disabling YogaSMC, fan and performance controls are no longer available. F-keys besides Volume and Brightness will no longer work either. ## Compiling Intel Wi-Fi and Bluetooth Firmware kexts easily Chris1111 has created a helpful little app called [**Wifi-Intel-KextsBuilder**](https://github.com/chris1111/Wifi-Intel-KextsBuilder) which automates the process of compiling Intel Wi-Fi and Bluetooth Firmware kexts. It only requires you to have Xcode installed and will handle the rest on its own once you run it. Wifi-Intel-KextsBuilder downloads the source code of itlwm, IntelBluetoothFirmware, MacKernelSDK and Lilu and then compiles itlwm, AirportItlwm and Intel Bluetooth Firmware kexts. They will be located under "Users/YOUR_USERNAME/Developer/Wifi-Intel-KextsBuilder/ in the "build/Release" folder of each repo. These kexts won't be slimmed like the ones present in my EFI folders but at least you now have a simple option to compile them on your own in the future. For compiling slimmed kexts, you can [follow my guide](https://github.com/5T33Z0/Thinkpad-T490-Hackintosh-OpenCore/tree/main/Additional_Files/Slimmed_Kexts/Intel_AC-9650) to do so. ## Credits and Thank Yous - [**Acidanthera**](https://github.com/acidanthera) for OpenCore, Kexts and maciASL - Chris1111 for [**Wifi-Intel-KextsBuilder**](https://github.com/chris1111/Wifi-Intel-KextsBuilder) - [**CorpNewt**](https://github.com/corpnewt) for ProperTree, CPUFriendFriend and SSDTTime - Dreamwhite for slimmed versions of [**itlwm.kext**](https://github.com/dreamwhite/Chonky-itlwm-Build/releases) - [**ic005k**](https://github.com/ic005k/OCAuxiliaryTools) for OpenCore Auxiliary Tools - [**benbaker76**](https://github.com/benbaker76/Hackintool) for Hackintool - [**zxystd**](https://github.com/zxystd/BrcmPatchRAM) for Sonoma-compatible BrcmPatchRAM kext - **Special Thx to**: - [1Revenger1](https://github.com/1Revenger1/) for VoodooRMI and fixing issues with the TrackPad - deeveedee for advice when trying to optimize the framebuffer patch for connecting to my external display. - **T490 OpenCore Repos** used for referencing and ACPI hotfixes: - [yusifsalam](https://github.com/yusifsalam/t490-macos) - [Krissh-C ](https://github.com/Krissh-C/T490-macOS) - [ganyuanzhen](https://github.com/ganyuanzhen/T490-Hackintosh-Opencore) - [laserdyke](https://github.com/laserdyke/t490-opencore) - [ZoR3oL](https://github.com/ZoR3oL/t490-hackintosh)
