Airport WiFi on Sequoia for Laptop Dell Latitude E5550

[nabilh2020]

I can get the itlwm.kext to work for networking & Internet using Heliport & itlwm.kext.

But could not get the WiFi to work using the Ventura kext AirportItlwm.kext.

Couldn't get Bluetooth to work either.

It works for Ventura both & BT.

In order to be able to boot I have to set IOSkywalkFamily.kext to false in the Kernel Add section, otherwise I get a Kernel panic on boot.

I will try to patch using this as advised:

Code:
Find: 5F505330<br>Replace: 58505330<br>Comment: Rename _PS0 to XPS0 (credit: EliteMacx86)

FWIW I am including a link to my dropbox for relevant (EFI partition content, config.plist & IOReg both with spoof & no spoof)

Will appreciate if you fix my config.plist, please note I have to set in Kernel add kext IOSkywalkFamily.kext as false otherwise it won't boot, & the Block section is as you suggested.

Thanks in advance

PS: with the patch it now keeps seeking, but no WiFi listed spots, if it is mandatory to set IOSkywalkFamily.kext to true in the Kernel Add section, it just boots to a kernel panic saying "a relinked copy with different executable UUID already present"

& yes I commented out the Broadcom spoof, doesn't work commented out or not, also reset NVRAM thrice...

This is the corrected config.plist which comments out the Broadcom spoof after the OCLP root parch, still no WiFi despite making the DSDT patch:

Talking to myself...
Anyway, something weird happened, I can't spoof Intel as Broadcom anymore, & Bluetooth worked, config.plist does now work anymore...ill give it a rest for now, got more important fish to fry...

There are severals files. Please attach the main EFI with the Intel WiFi guide described here. It doesn't matter if it doesn't boot or throws Kernel panic.

OK this is the last EFI I got which works with itlwm.kext & bluetooth commenting out all related AirportItlwm.kext related hacks...
but it says the file is too large for the server to process... so I will put up a link to it in my dropbox...

I just upgraded to 15.7.4 & an interesting development occurred...
Bluetooth works without the two entries in the NVRAM section anymore, as if you leave them you get a boot loop.
So I get with itlwm kext everything working.

Will try my luck again to see if upgrading to 15.7.4 removes the kernel panic occurring with ioskyfamily.kext ...

So I will remove the two bluetooth entries in the NVRAM section & false itlwm.kext & true the corresponding rest, & see what happens, I don't hold my breath it will give a kernel panic.

Yes ,no change, gives still same kernel panic.

Bluetooth works without having to do anything if one uses the itlwm.kext route.

PS - I will carry on logging my experiments on the thread I created for that purpose, there are small adjustments I test which need to be looked for me to keep track of what I do, at least Premium will indulge me this

Thiere was a small glitch on a configuration just using itlwm.kext & the rest of the relevant settings, this was following some of the advice to get Airport working available through this site.

I kept having boot loops even though I cleaned mostly just for using itlwm.kext. Booting into safe mode was fine.
I found out that one setting would create the boot loop, but it was not in fact the Bluetooth parameters in NVRAM, in fact those parameters didn't create the issue but fixed Bluetooth.

The culprit setting is in config.plist -> Misc -> Security tab.
It is advised to set SecureBootModel to Disabled, for my configuration that created a boot loop, the correct setting I found to work was in fact Default, not Disabled.
Doing so fixes the boot loop without having to boot to safe mode to have access.

I am including the confirmation.plist for reference that works for me with itlwm.kext with everything else working.

I wanted to get Airport to work out of curiosity, my main Computer usage is in Windows, but as a hobby I like tinkering with other operating systems.
