Read the following documentation carefully in order to install/boot macOS successfully! |⚠️ Important Notes |:-----------------------| | The **Samsung PM981a NVMe** that comes with the system is NOT compatible with macOS. You **_must_** use a different, compatible NVMe drive! | ## Notable Features - [x] Proper Hibernation (Modes 3 and 25 supported) - [x] Cleaner implementation of `_OSI` checks - [x] Optimized Framebuffer Patch for smoother handshake with external displays - [x] Added Disable BDPROCHOT driver to fix performance issues after waking from S3/S4 sleep. - [x] Working Thunderbolt 3 over USB-C - [x] New USB Port Mapping with docking station support - [x] Working clamshell mode (when connected to A/C and external display) - [x] Working 3D globe in Maps app (macOS 12+) - [x] No injection of `PlatformInfo` data into Microsoft Windows. - [x] Lean EFI folder with slimmed kexts (20 MB instead of 62 MB): - **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 - [ ] Fingerprint reader → incompatible with macOS - [ ] Infrared portion of integrated camera unsupported by macOS → So moving the frontside switch to the left actually disables the camera in macOS (if you don't want to disable it in BIOS) - [ ] SDCard Reader only works when a card is inserted prior to booting (→ see [issue 59](https://github.com/0xFireWolf/RealtekCardReader/issues/59)) - [ ] YogaSMC hasn't been update in years, causes issues and is incompatibel with macOS Tahoe. That's why it's disabled by default > [!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] Adjusted Framebuffer Patch so HDMI/DP Ports on docking stations can be utilized - [x] Adding USB ports of docking station to the USB port kext - [ ] Creating an AppleALC Layout-ID for audio output on Docking Station --- ## 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) **UEFI BIOS** | v1.84 (2025-07-03) **EC** | v1.27 **ME Firmware** | v12.0.95.2489 **CPU** | Intel [**Intel Core i5 8265U**](https://ark.intel.com/content/www/us/en/ark/products/149088/intel-core-i58265u-processor-6m-cache-up-to-3-90-ghz.html) (Quad Core) **RAM** | 16 GB:
