How to configure Broadcom WiFi in Sonoma (if not detected automatically)

A collection of instructions and links to make Broadcom Wifi work natively again under macOS 14 and 15 (Sonoma/Sequoia). Those instructions are already implemented in the EFI, but STEP 9 is required (OCLP). <br/> <br/> This process involves disabling SIP, so be warned. <br/> <br/> Below is a description of what to do.

STEP 1: Disable Gatekeeper.

Under Terminal, run the following:

sudo spctl --master-disable

STEP 2: Download and install Kernel Debug Kit:

From source: Kernel Debug Kit

STEP 3: Download OCLP but do not install yet:

From source: OCLP

STEP 4: Make a copy of your current and working EFI. Copy /EFI/OC/config.plist as /EFI/OC/config-backup.plist

STEP 5: System Integrity Protection must be set to 0x803. How to do that? Editing /EFI/OC/config.plist manually or using OpenCore Configurator (highly advisable). Set your SIP to Disabled: under NVRAM section, search 7C436110-AB2A-4BBB-A880-FE41995C9F82 key, then search csr-active-config key and set to 30800000. Or (manually editing /EFI/OC/config.plist):

                    <key>csr-active-config</key>
                    <data>AwgAAA==</data>

STEP 6: Change SecureBootModel to Disabled. How to do that? Under Misc section, security tab, search for SecureBootModel key and set it to Disabled, or (manually editing /EFI/OC/config.plist):

                <key>SecureBootModel</key>
                <string>Disabled</string>

STEP 7: Enable Kexts and Block Patch. How to do that? Under Kernel section, under ADD tab, enable IOSkywalkerFamily.kext. Additionally, Under Kernel section, under BLOCK tab, enable Allow IOSkywalker Downgrade.

Or (manually editing /EFI/OC/config.plist):

To enable IOSkywalkerFamily.kext kext:

                <dict>
                    <key>Arch</key>
                    <string>Any</string>
                    <key>BundlePath</key>
                    <string>IOSkywalkFamily.kext</string>
                    <key>Comment</key>
                    <string>V1.0</string>
                    <key>Enabled</key>
                    <true/>
                    <key>ExecutablePath</key>
                    <string>Contents/MacOS/IOSkywalkFamily</string>
                    <key>MaxKernel</key>
                    <string></string>
                    <key>MinKernel</key>
                    <string>23.0.0</string>
                    <key>PlistPath</key>
                    <string>Contents/Info.plist</string>
                </dict>

To enable Allow IOSkywalker Downgrade patch:

                <dict>
                    <key>Arch</key>
                    <string>Any</string>
                    <key>Comment</key>
                    <string>Allow IOSkywalk Downgrade</string>
                    <key>Enabled</key>
                    <true/>
                    <key>Identifier</key>
                    <string>com.apple.iokit.IOSkywalkFamily</string>
                    <key>MaxKernel</key>
                    <string></string>
                    <key>MinKernel</key>
                    <string>23.0.0</string>
                    <key>Strategy</key>
                    <string>Exclude</string>
                </dict>

STEP 8: Save your modified EFI and reboot the system. Cross fingers... System must boot smoothly if everything performed as described.

STEP 9: Run OCLP and install Root Patch for Modern Wifi (Needed after every update). How to do that? Open OCLP (downloaded at step 3) and click on "Root Patch"

STEP 10: Reboot and check for native Broadcom Wifi. If it's not working, simply reset your NVRAM and check again.

All credits go to the OCLP team, I merely put everything together for ease of use (for me, at least).

Change DVMT and CFG Lock

You must unlock CFG Lock , otherwise, you can't use both OpenCore and Clover.
We recommend to change DVMT into 64M, there's no damage to your computer.

• Recommend: get into hidden BIOS
  • The way to enter hidden BIOS
    • Switch off the OneKeyBattery
    • Press following buttons with your computer closed.
      • F4 → 4 → R → F → V
      • F5 → 5 → T → G → B
      • F6 → 6 → Y → H → N
      • Power on → Press F2, speed up if failed.

• Change the following settings.
  • Advanced → Power & Performance → CPU - Power Management Control → CPU Lock Configuration → CFG Lock → Disabled
  • Advanced → System Agent (SA) Configuration → Graphics Configuration → DVMT Pre-Allocated → 64M

• Backup solution: change in Windows

  • Refer to https://github.com/lietxia/XiaoXinAir14IML_2019_hackintosh/wiki/DVMT

  • DVMT：

    • Area : SaSetup

SSDT

Notes

• You need a T6 screwdriver to disassemble the machine. After the screws are removed, use the unused card and carefully disassemble it from the other side of the screen https://www.bilibili.com/video/BV1X341157kf/
• If you want to buy a type-c cable, you should buy one with 4mm diameter, and the hole diameter is 1.7mm
