I tested this with a Fenvi T919 card on Sequoia 15.1. This guide should work with most Broadcom cards that worked natively under Ventura, but there may be exceptions. \ **This process involves disabling SIP and AMFI, so be warned:** *Modifying the system with OCLP Requires SIP, Apple Secure Boot and AMFI to be disabled so there are some compromises in terms of security.*

**1. Get kexts** * Check and download the latest version of AMFIPass-v1.4.1-RELEASE.zip * Check [https://github.com/dortania/OpenCore-Legacy-Patcher/tree/main/payloads/Kexts/Wifi ]()and download the latest version of IOSkywalkFamily-v1.2.0.zip and IO80211FamilyLegacy-v1.0.0.zip Extract and add these Kexts to your EFI folder: * AMFIPass.kext * IOSkywalkFamily.kext * IO80211FamilyLegacy.kext **2. Edit config.plist** Edit your config.plist so that it reflects these changes: 2.1 - Add the new kexts to your existing ones (Kernel - Add)

``` Arch Any BundlePath AMFIPass.kext Comment V1.4.1 Enabled ExecutablePath Contents/MacOS/AMFIPass MaxKernel MinKernel PlistPath Contents/Info.plist Arch Any BundlePath IOSkywalkFamily.kext Comment V1.0 Enabled ExecutablePath Contents/MacOS/IOSkywalkFamily MaxKernel MinKernel 23.0.0 PlistPath Contents/Info.plist Arch Any BundlePath IO80211FamilyLegacy.kext Comment V1200.12.2b1 Enabled ExecutablePath Contents/MacOS/IO80211FamilyLegacy MaxKernel MinKernel 23.0.0 PlistPath Contents/Info.plist Arch Any BundlePath IO80211FamilyLegacy.kext/Contents/PlugIns/AirPortBrcmNIC.kext Comment V1400.1.1 Enabled ExecutablePath Contents/MacOS/AirPortBrcmNIC MaxKernel MinKernel 23.0.0 PlistPath Contents/Info.plist ``` 2.2 - Allow for IOSkywalk kext downgrade by excluding it (Kernel - Block)

``` Arch Any Comment Allow IOSkywalk Downgrade Enabled Identifier com.apple.iokit.IOSkywalkFamily MaxKernel MinKernel 23.0.0 Strategy Exclude ``` 2.3 - Change SecureBootModel to Disabled (Entries - Security)

``` SecureBootModel Disabled ``` 2.4 - Set your SIP to be partially disabled (NVRAM - Add - 7C436110-AB2A-4BBB-A880-FE41995C9F82)

``` csr-active-config AwgAAA== ``` * csr-active-config is `03080000` in a plist editor * Double check your config.plist **3. Reboot** * Reboot into OpenCore, press the *Space* key. Reset your NVRAM and continue booting. * Download OCLP from here: * Open OCLP and select Root Patching *(needed after every update)*. It will ask you to reboot again after it finishes patching. **4. Activate AppleVTD** * This may be optional for some cards, but for my Broadcom BCM94360CD based Fenvi FV-T919 Wifi PCIe card, this step was required. 4.1 Patch DMAR * You may need to enable VT-D in your BIOS already in order to be able to download the DMAR table * Use the following guide: [Patching DMAR Table: Manual](https://dortania.github.io/Getting-Started-With-ACPI/Universal/dmar-methods/manual.html) or use [SSDTTime](https://dortania.github.io/Getting-Started-With-ACPI/ssdt-methods/ssdt-easy.html#running-ssdttime)

4.2 Edit config.plist * ACPI --> Add * Make sure your new patched DMAR.aml file is in your EFI Partition's `EFI/OC/ACPI` folder and also added to your `config.plist`

                <dict>
                    <key>Comment</key>
                    <string></string>
                    <key>Enabled</key>
                    <true/>
                    <key>Path</key>
                    <string>DMAR.aml</string>
                </dict>

* Kernel --> Quirks

``` DisableIoMapper DisableIoMapperMapping ``` * ACPI --> Delete

``` All Comment Drop DMAR table Enabled OemTableId TableLength 0 TableSignature RE1BUg== ``` * TableSignature is `444D4152` in a plist editor 4.3 In the BIOS set * VT-d --> Enabled 4.4 Check AppleVTD * Reboot * Download and open [IORegistry Explorer ](https://github.com/utopia-team/IORegistryExplorer/releases) * In IOReg search for `AppleVTD` * If enabled, the AppleVTD property can be seen under the AppleACPIPlatformExpert node

**5. Check** * Reboot and check for native Wifi. If it's still not working, reset your NVRAM and check again. * Test Wifi transmission speed using: `Option Click -> Wifi menu bar icon -> check Tx Rate` and run an internet speed test.

### Notes * Additional kexts may be needed for Bluetooth * [Broadcom WiFi and Bluetooth ](https://github.com/5T33Z0/OC-Little-Translated/tree/main/10_Kexts_Loading_Sequence_Examples#example-7-broadcom-wifi-and-bluetooth) ### **Credits** * [5T33Z0](https://github.com/5T33Z0/OC-Little-Translated/tree/main/14_OCLP_Wintel) detailed instructions for OCLP on Hackintosh, a [Wifi on Sonoma](https://github.com/5T33Z0/OC-Little-Translated/blob/main/14_OCLP_Wintel/Enable_Features/WiFi_Sonoma.md) page and a guide for [Replacing the `DMAR` table by a modified one](https://github.com/5T33Z0/OC-Little-Translated/blob/4f5b83b0d343e504f4babc427df5b42128fb2dc3/00_ACPI/ACPI_Dropping_Tables/README.md#example-2-replacing-the-dmar-table-by-a-modified-one) * [OCAuxiliaryTools](https://github.com/ic005k/OCAuxiliaryTools): screenshots of the config which was edited using OCAuxiliaryTools * [OCLP team](https://github.com/dortania/OpenCore-Legacy-Patcher/) who made this possible, even though they don't officially support OCLP on Hackintosh * [billabongbruno](https://github.com/billabongbruno/macOS-Sonoma-Broadcom-Wifi) with an older such guide on Github * [u/6e656f73](https://www.reddit.com/user/6e656f73/) on r/hackintosh especially for the AppleVTD tip :-) Comments and discussion can be found on r/hackintosh: [Broadcom Wifi on macOS Sonoma and Sequoia (Fenvi T919 and others)](https://www.reddit.com/r/hackintosh/comments/1gvu5n1/broadcom_wifi_on_macos_sonoma_and_sequoia_fenvi/)
