This is a guide to get AMD/ATI/Sapphire/ATI Radeon HD 6450 work OOB in mac os X el capitan.
Most of the people say that radeon HD 6450 is not supported by mac os and you have to use a different framebuffer or spoof the device id to get it working but it becomes very tricky to do that and is almost impossible to one who is new to hackintosh. So I decided to make a simple guide to make the card working OOB in el capitan without doing much.
The steps in this guide are tested by me on a Sapphire Ati Radeon HD6450 2GB card.
So for that you must be using clover bootloader (UEFI or legacy).
If you don't have clover then download it from here https://github.com/CloverHackyColor/CloverBootloader/releases/download/5119/Clover_r5119.pkg
Now the next step is to get the required kexts. You need the following kexts to get it work.
1 - FakeSMC.kext
2 - Lily.kext
3 - Whatevergreen.kext
4 - AMD6000controller.kext
5 - AMDRadeonX3000.kext
6 - AMDRadeonX3000GLDriver.bundle
7 - AppleACPIPS2Nub.kext
8 - ApplePS2controller.kext
9 - IOAccelerator2D.plugin
10 - IOAcceleratorFamily2.kext
11 - NullCPUPowerManagement.kext
Now you would be worried that how you will get these kexts but you don't need to worry about it you can get all of them from here https://drive.google.com/file/d/18qP2B0Cpo2hay-qMlAl5H7Qbv3rLyHQu/view?usp=drivesdk
The next step is to get clover configurator to configure your EFI partition you can download the configurator from here https://www.macupdate.com/action/download/61090
Now open clover configurator and mount EFI partition and open EFI partition and open clover folder and open kexts/ other and paste the kexts there now open clover folder and open config.plist and go to graphics tab and check inject ATI Now save the config.
Now restart your hackintosh and You will see in about my mac that your radeon card is working OOB.
Hope it helped you and happy hackintoshing!!!!
