Tools Needed

1. Use KextUtility to install kexts

2. Use DSDTEditor to edit DSDT

3. Use PlistEdit Pro to edit plist

Here I list three methods to make ATI Radeon HD 5450 working. Method 1 & 2 applies for newbies, method 3 for advanced users. You can use any one of the method upon your interest

**Backup all kexts before patching**

Method 1

1. Install ATI5000Controller.kext & AMDRadeonAccelerator.kext

2. Use the below flag in Extra/org.chameleon.boot.plist

<key>ATIConfig</key>
<string>Eulemur</string>
<key>GraphicsEnabler</key>
<string>Yes</string>

3. Reboot

**This method will work for most Sapphire Radeon Cards**

Method 2

1. Install ATI5000Controller.kext, AMDRadeonAccelerator.kext & EVOenabler.kext

2. Use the below flag in Extra/org.chameleon.boot.plist

<key>GraphicsEnabler</key>
<string>Yes</string>

3. Reboot

Known issues for method 1 & 2

a. Display over HDMI will not wake from sleep sometime

Method 3

1. Install ATI5000Controller.kext & AMDRadeonAccelerator.kext

2. Patch DSDT.aml with ATI 5450 DSDT patch attached and place the patched DSDT.aml in Extra folder

3. The patch includes working HDMI Audio edit. For some cards AppleHDA needs to be patched to get sound from HDMI

4. Remove all Graphics related flags in Extra/org.chameleon.boot.plist

5. Reboot. No wakeup issues like the one, mentioned in method 1 & 2

Patching AppleGraphicsPowerManagement.kext (AGPM)

a. Common for all three methods listed above

b. Patch AppleGraphicsPowerManagement.kext (Patch is included in download), repair permissions and update system cache 

c. Reboot. Open terminal, type “kextstat” without quotes and check if com.apple.driver.AGPM is loaded

d. Those who don’t want to patch AppleGraphicsPowerManagement.kext, rename/delete it from S/L/E

COMMON ISSUES

a. Reduced frame rate after system wake from sleep. Fix: Change SMBios.plist to iMac or Mac mini and that will fix the problem

b. If your card has different frame buffer i.e Eulemur, change it to new one in DSDT Patch/EVOenabler/boot flag or all
