🔧 Fix Broadcom BCM43142 Wi-Fi on macOS 26 (Step-by-Step)

guide Hackintosh
--
⚠️ Important: This guide works for macOS Sonoma and later versions. Apple dropped native Broadcom Wi-Fi support in Sonoma. This requires OpenCore and kext injection to work.

1. Download Required Kexts

2. Install Kexts in EFI Partition

  1. Boot into OpenCore (your custom bootloader)
  2. Mount your EFI partition (typically /EFI/OC)
  3. Copy all downloaded kexts to: EFI/OC/Kexts

3. Configure config.plist

  • Open your config.plist file
  • Go to Kernel > Add section
  • Add the following entries (ensure correct paths and versions):

    <dict>
        <key>Arch</key>
        <string>Any</string>
        <key>BundlePath</key>
        <string>AMFIPass.kext</string>
        <key>Comment</key>
        <string>V1.4.1</string>
        <key>Enabled</key>
        <true/>
        <key>ExecutablePath</key>
        <string>Contents/MacOS/AMFIPass</string>
        <key>MinKernel</key>
        <string>23.0.0</string>
    </dict>
    <dict>
        <key>Arch</key>
        <string>Any</string>
        <key>BundlePath</key>
        <string>IOSkywalkFamily.kext</string>
        <key>Comment</key>
        <string>V1.2.0</string>
        <key>Enabled</key>
        <true/>
        <key>ExecutablePath</key>
        <string>Contents/MacOS/IOSkywalkFamily</string>
        <key>MinKernel</key>
        <string>23.0.0</string>
    </dict>
    <dict>
        <key>Arch</key>
        <string>Any</string>
        <key>BundlePath</key>
        <string>IO80211FamilyLegacy.kext</string>
        <key>Comment</key>
        <string>V1200.12.2b1</string>
        <key>Enabled</key>
        <true/>
    </dict>

4. Reboot & Verify

  1. Reboot into macOS
  2. After booting, check your Wi-Fi status in System Settings
  3. Test connectivity: Option-Click WiFi icon > Check Tx Rate
✅ Success: If Wi-Fi works natively without needing to inject kexts again, you're good to go!
❌ Failure: If not working, ensure your kexts are correctly installed and your OpenCore is properly patched with OCLP.
