Prime B460i-PLUS hackintosh

OpenCore configuration for running macOS 15 on the ASUS Prime B460i-PLUS motherboard. Without obsolete or cosmetic patches, the goal is simply macOS 15 working well on (mostly if you want WiFi) compatible hardware

Notes

• For features listed as in-scope that are not working as expected, it may be beneficial for all to open an issue here
• Where something is listed as out-of-scope more explicit information will surely be found in various places across the internet, or in the OpenCore documentation
• TextMate (github.com/textmate/textmate) is free software useful for editing config.plist
• WiFi with m.2 Broadcom BCM94360NG works in macOS 15 with downgraded/patched/blocked kernel extensions and OCLP root patching for modern WiFi
• The Bluetooth of m.2 Broadcom BCM94360NG works natively
• The repo contains files that are invisible in Finder according to a hidden file visibility toggle (Command + Shift + .)
• The EFI shell has the csrutil command e.g. csrutil status, csrutil enable, csrutil disable 0x803 for controlling the value of the csr-active-config NVRAM variable
• Use reset, reboot or resetsystem after using csrutil or edit to change config.plist settings or NVRAM variables
• Using more than one display with Intel HD 630 has issues

Intel Graphics

Edit the DeviceProperties section of your config.plist according to your configuration

Connectorless (using PCIe AMD GPU)

The default config.plist in this repo is configured in this way

...
<key>DeviceProperties</key>
<dict>
    <key>Add</key>
    <dict>
        ...
        <key>PciRoot(0x0)/Pci(0x2,0x0)</key>
        <dict>
            <key>AAPL,ig-platform-id</key>
            <data>AwCYPg==</data>
        </dict>
        ...
    </dict>
</dict>
...

Attached Display

Intel graphics should work well with a single display. Prefer DisplayPort instead of HDMI where possible

SMBIOS

What's this?

OpenCore will generate a complete SMBIOS for your system according to information provided in the PlatformInfo section of config.plist and a dataset derived from Apple firmwares. GenSMBIOS is a python script that uses acidanthera's macserial to generate required serials and unique identifiers

Edit the PlatformInfo section of your config.plist so that the MLB, ROM, SystemSerialNumber and SystemUUID values are unique to your machine

...
<key>PlatformInfo</key>
<dict>
    ...
    <key>Generic</key>
    <dict>
        ...
        <key>MLB</key>
        <string>M0000000000000001</string>
        ...
        <key>ROM</key>
        <data>ESIzRFVm</data>
        ...
        <key>SystemSerialNumber</key>
        <string>W00000000001</string>
        <key>SystemUUID</key>
        <string>00000000-0000-0000-0000-000000000000</string>

Reset NVRAM

At the picker, press space, choose Reset NVRAM

Reset NVRAM at first boot and whenever the bootloader files have changed

Post-Install

System Integrity Protection

The csrutil command from AcidAnthera/OpenCorePkg is available from the EFI shell. System Integrity Protection can be enabled/disabled in NVRAM with, for example, csrutil enable and csrutil disable 0x803

The default in config.plist is enabled, resetting NVRAM will re-enable System Integrity Protection. Use csrutil in EFI shell to disable it, for example, while adding a .VolumeIcon to the /System/Volumes/Preboot/UUID directory, or at the root of the Preboot volume, or for root patching with OpenCore Legacy Patcher

USB

Generate a valid USBPorts.kext

Refer to README-usbtool.command.md

NVMe

NVMeFix is a set of patches for the Apple NVMe storage driver, IONVMeFamily. Its goal is to improve compatibility with non-Apple SSDs
