Airport WiFi on Sequoia for Laptop Dell Latitude E5550

Of course, it does not harm. But still unnecessary. If the IONetworkingFamily isn't loading, then only force option should be used. Many people just don't have the real reason and simply copy/paste or following blindly doesn't make sense.

The EFI still needs a few optimizations:
Remove ResetLogoStatus
Remove the spoof so that the WiFi chip can have the native IDs.
VT-d is still not implemented.
You should remove the OCLP-Settings entry from the NVRAM.
Why are you still using AMFIPass.kext and amfi=0x80 together? Use either one of them, never both.
You should disable the dGPU by patching the DSDT and SSDT. The -wegnoegpu flag simply hides it from the OS but still draws power.

VT-d is still not implemented?
It is implemented in the BIOS. I didn't understand what entry to use in the config.plist.

Disable the dGPU by patching the DSDT and SSDT?
No idea how to do it.

AMFIPass.kext and amfi=0x80?
Will remove amfi=0x80.

Remove the spoof so that the WiFi chip can have the native IDs?
The spoof was removed, otherwise it won't activate WiFi.

Remove ResetLogoStatus?
Need to locate where it is listed...

All these will be trialled on the EFI for Sonoma as it showed some instability crashing after a couple of hours.
Sequoia is very stable.

Side note - I never do things on my own, I always piggy back on users who got setups similar to mine, have been doing like this since I started using PCs back in 1994.
