You can download the bios here to install it from Windows, or follow this guide if you don't have Windows on your Thinkpad. Please note that the WiFi card the X220 comes with is not compatible with Mac OS, so you'll have to install a replacement for this guide I'll be using the Atheros AR9285.īefore starting, you'll have to prepare your Thinkpad to run Mac OS by installing a custom bios. I've just uploaded the latest version.To complete this guide, you will need access to another computer with Mac OS, a 16+ GB USB stick, and Clover Configurator (y'know, the usual :P). So again I would appreciate it if I could get some testing and feedback on this feature. When you select "Auto" from the "Type" combo box it will add two entries for each resolution (HiDPI 3 and HiDPI 4). I'm not entirely sure what the difference is between these so if anyone can help tell me figure it out maybe I can rename them to something more meaningful. Note that xxxxxxxx yyyyyyyy is Width * 2 and Height * 2 respectively. Auto: Adds both a HiDPI 3 and HiDPI 2 entry So based on the one-key-hidpi script they correspond to the following resolution formats: So what do does HiDPI 1, HiDPI 2, HiDPI 3, HiDPI 4 and Auto type's mean? So based on your selection in the Resolution combo box we add the following resolutions: You can then click the Add button to add additional custom resolutions Click the Export button to generate the files to your desktopĤ. Click on the Add button to add the resolutions you have selected (1080p by default)ģ. Launch Hackintool and go to General->Display tabĢ. So to patch your EDID the process goes like this:ġ. So it would be great if I can get some clarification on exactly where I should and shouldn't inject this info to change these values. I'm not sure if I need to only inject this into the EDID or if I need to include it in the folder and file name or the DisplayProductID / DisplayVendorID values into the actual file itself (which is just a plist file). I was wondering if you all could help test this feature? I am pretty sure it's all working okay except for the "Inject Apple Info" feature which injects a Product ID of 0x9C7C (40060) and Vendor ID of 0x0610 (1552). I have updated Hackintool so that you can add the resolutions just like the one-key-hidpi script. Perhaps can give some anecdotal evidence of it working? If someone here has successfully spoofed their GPU device-id and it's worked I'd like to hear about it. I am trying to remember if I can recall anyone using device-id injection and it being successful. The other 2 bytes we leave blank which is the "Product ID" but that value is always going to be 0x8086 which refers to "Intel" and is always injected no matter what. It is the "Device ID" of the video hardware which you can see in System Information->Graphics/Displays. AppleIntelSKLGraphicsFramebuffer.kext/Contents/ist/IOKitPersonalities/AppleIntelFramebufferController/IOPCIPrimaryMatch. Now I know it's from a list of values stored in the framebuffer kext. Yes I used to inject device-id automatically based on the ig-platform-id value but that was not correct. So you might want to include that in your guide. I recently updated my Intel Framebuffer patching using WhateverGreen guide to include a section called "Spoofing Intel CPU Gen" which can also require using the lilucpu=N boot flag. I think sometimes it's necessary but I don't know a lot about it. Well if your hardware device-id matches the one for the ig-platform-id then I generally don't think spoofing the device-id is necessary. Building a CustoMac Hackintosh: Buyer's Guide
