Hardware compatibility

This EFI will suit any P300 regardless of CPU model¹ / RAM amount / Storage drive (SATA or NVMe²).

1: Follow CPU Power Management guide

2: Some NVMe drives may not work OOTB with MacOS, NVMeFix could resolve some issues.

Post-install

USB ports mapping

USBMap.kext is used to map needed ports. If you need a different configuration follow USBMap guide

Custom CPU Power Management

If you happen to have a different CPU model remove CPUFriend.kext and replace SSDT-CPUD with plain SSDT-PLUG, power management is natively supported by OpenCore anyway. If you want to take a step forward and create a custom profile, follow these steps:

• Run the following command in Terminal:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/stevezhengshiqi/one-key-cpufriend/master/one-key-cpufriend.sh)"

• Copy CPUFriend.kext and CPUFriendDataProvider.kext from desktop to /OC/Kexts/.

• Open /OC/config.plist and add the following code:

<dict>
    <key>BundlePath</key>
    <string>CPUFriend.kext</string>
    <key>Comment</key>
    <string>Power management data injector</string>
    <key>Enabled</key>
    <true/>
    <key>ExecutablePath</key>
    <string>Contents/MacOS/CPUFriend</string>
    <key>MaxKernel</key>
    <string></string>
    <key>MinKernel</key>
    <string></string>
    <key>PlistPath</key>
    <string>Contents/Info.plist</string>
</dict>
<dict>
    <key>BundlePath</key>
    <string>CPUFriendDataProvider.kext</string>
    <key>Comment</key>
    <string>Power management data</string>
    <key>Enabled</key>
    <true/>
    <key>ExecutablePath</key>
    <string></string>
    <key>MaxKernel</key>
    <string></string>
    <key>MinKernel</key>
    <string></string>
    <key>PlistPath</key>
    <string>Contents/Info.plist</string>
</dict>

Enable Apple Services

• Do the following one line at a time in Terminal:

$ git clone https://github.com/corpnewt/GenSMBIOS
$ cd GenSMBIOS
$ chmod +x GenSMBIOS.command

• Run with either ./GenSMBIOS.command or by double-clicking GenSMBIOS.command

• Type iMac15,1 10

• Add the last results to PlatformInfo > Generic > MLB, SystemSerialNumber and SystemUUID

Enable HiDPI

• Disable SIP (just for this process, you can enable it once finished)

• Run this script in Terminal

bash -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh)"

Other tweaks

Monitor temperatures and power consumption

• Download and install HWMonitor
• Open the app and check launch on login option

Faster macOS dock animation

• Run these lines in terminal:

$ defaults write com.apple.dock autohide-delay -float 0
$ defaults write com.apple.dock autohide-time-modifier -float 0.5
$ killall Dock

Mac Bootloader GUI and Boot Chime

• Follow the appropriate Guide.

What's not working ⚠️

Nothing to mention so far

Update tracker 🔄

I don't own this workstation anymore. This configuration will hardly be updated in the future. As is, it will probably support every Catalina's update without any problem.

front audio

do the front audio ports work for you, the 3.5mm on the back work for me but the mic input and headphone output at the front don't work
