OCLP patcher: support for legacy Broadcom wireless cards in Sonoma

[Hervé]

OCLP v0.6.8 now provides support for Broadcom legacy wireless cards that Sonoma officially dropped. Good news for all of us relying on BCM4350/BCM4360xx cards for Wireless and Bluetooth services.

 

Not tried it yet but process is understood to be as follows with OpenCore (cf. dedicated Sonoma beta threads at Insanelymac.com):

1. add boot-arg amfi=0x80 (or amfi_get_out_of_my_way=1)
2. disable SIP with csr-active-config set to 0x803 (0x0FEF is Ok too)
3. block vanilla kext IOSkywalkFamily kext in the config file
4. disable SecureBoot if applicable
5. inject older kexts IOSkywalkFamily + IO80211FamilyLegacy kexts (in that specific order)
6. once booted with those settings, apply OCLP root patching and reboot
7. Broadcom wireless cards that were previously supported in Ventura are then expected to be operational again

Not sure this works with Clover given the lack of system's kext blocking facility afaik. Will try to test asap with OpenCore on my E7270.

Edit: This is fully supported with Clover r5157 and later.
