## About
OpenCore EFI folder and config for running macOS Sonoma and newer on the Lenovo ThinkPad T490. Read the following documentation carefully in order to install/boot macOS successfully!

### Before you begin
⚠️ The built-in Samsung PM981a NVMe 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] 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] 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.
- [x] YogaSMC support for additional features like CPU fan control, performance bias, handling Fn Keyboard shortcuts, additional OSD overlays, etc.
- [x] No injection of `PlatformInfo` data into MS Windows.
- [x] Working 3D globe in Maps app (macOS 12+)

### Known Issues
- [ ] In general, the system runs hotter under macOS than under Windows. My guess is that this is due to the required iGPU spoof.
- [ ] 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
- [ ] Adjusting Framebuffer Patch so HDMI/DP Ports on docking stations can be utilized

    ## 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)`
    - If you plan to install macOS 13.3 or older, disable/delete `enable-backlight-registers-alternative-fix` and use `enable-backlight-registers-fix` instead to fix black screen issues.
    - If other issues occur, try the other framebuffer patch in the config (the one that's disabled by `#`)!
    - An additional list of Framebuffer Patches can 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)):
    - Sonoma uses **AirportItlwm_Sonoma**
    - Sequoia uses **Itlwm** because there's no AirportItlwm variant for Sequoia yet
    - **Kernel/Quirks**:
    - `AppleXcpmCfgLock` is not required on my system. Try for yourself if your T490 can boot without it.
    - **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 stored in `USBMap_MBP152.kext` won't be applied and Bluetooth won't work either! If you must change the SMBIOS then you also need to change the `model` property inside the `info.plist` of the kext to match the selected SMBIOS as well ([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 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)
    - **Pro**: Can be used during macOS Setup/Recoveery 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 Sequoia)
    - **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 other macOS versions than Sonoma or Sequioa!
    
    > [!NOTE]
    >
    > My config uses `AirportItlw.kext` 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 is included. My `itlwm.kext` is a slimmed-down version only containing the firmware for the Intel AC-9560 (1,5 MB instead of 16,1 MB). If you want to use itlwm, disable AirportItlwm (all variants) and enable itlwm in the config.plist instead. Next, download the Helipad 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**: `sudo spctl --master-disable` because it is annoying and wants to stop you from running scripts from github etc. This command no longer works in macOS Sequoia – it requires a [different method](https://github.com/5T33Z0/OC-Little-Translated/blob/main/14_OCLP_Wintel/Guides/Disable_Gatekeeper.md) to disable Gatekeeper.
    - **Wi-Fi** (`itlwm.kext` users only):
    - 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.
    - **YogaSMC**:
    - 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
    - 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.
    - **Enabling Hibernation**: Use Terminal or change in Hackintool
    - Disable PowerNap: `sudo pmset -a powernap 0`
    - Change Hibernatemode to 25: `sudo pmset -a hibernatemode 25`
    
    ## 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:
    
    - 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.
    
    ## For OCAT Users
    Add the following entries to the "Kext URL Upgrade" list accessible via "Settings" from the "Sync" window (if not present already), so kext which are marked in grey in the Sync window will be downloaded when checking for updates:
    
    Kext Name | Source URL
    ----------|-----------
    **AdvancedMap.kext** | https://github.com/notjosh/AdvancedMap
    **AirportItlwm.kext** | https://github.com/OpenIntelWireless/itlwm
    **AMFIPass.kext** | https://github.com/dortania/OpenCore-Legacy-Patcher
    **IntelBluetoothFirmware.kext** | https://github.com/OpenIntelWireless/IntelBluetoothFirmware
    **IntelMausiEthernet.kext** | https://github.com/CloverHackyColor/IntelMausiEthernet
    **itlwm.kext** | https://github.com/OpenIntelWireless/itlwm
    **RealtekCardReader.kext** | https://github.com/0xFireWolf/RealtekCardReader
    **RealtekCardReaderFriend.kext** | https://github.com/0xFireWolf/RealtekCardReaderFriend
    
    > [!IMPORTANT]
    >
    > Don't update `AirportItlwm.kext`, `AppleALC.kext`, `IntelBluetoothFirmware.kext` and `itlwm.kext` because then you lose the slimmed versions of these kexts!
    
    ## 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.
