THE Solution:Dell DW1820A (Broadcom BCM94350ZAE) macOS 15

For this reason this card will increase the price in the market.
As soon as the sellers see that it is not problematic and works similar to the BCM94352Z
It's totally insane that this card costs this much - i bought the whole laptop for this money

Does anyone know how to get bluetooth properly working?

I have tried @gaghost's kexts, and while they establish a proper connection, I cannot switch sound over to my AirPods.

I also tried BrcmBluetoothInjector+BrcmFirmwareData+BrcmPatchRAM2 (should be same as @gaghost?) and I get no Wifi and Bluetooth.

Replacing BrcmPatchRAM2 for BrcmPatchRAM3 yields working wifi, and Bluetooth can establish a non-working connection.

because ASPM is disabled only for Wifi card, other PCI devices, such as video, card reader, SATA controller, etc. still have ASPM enabled.

You were right. Not a permanent solution to disable everything. i am now disabled only WiFI slot - in BIOS - it is located as PCI Express 4 device in BIOS (from 1-6). Now I have very good results for the battery.It works perfectly fine. Stable.The CPU does not heat more than it needs. (I had a problem with overheating)

There is another variant for PCI Express Root port 4 on Lenovo G50-70.

By default BIOS settings - Automatic ASPM is on L0sL1 - that does not work OOB. When on L1 - it also doesn't work OOB. As well with Auto. When it stands on L0s - everything is fine. DW1820A Works OOB.

Thanks @Hugotai I've been struggling with this card for a long time, works perfectly on 13.3.5 for my XPS 13 (9333). The PCI path is a little different if you have this laptop mine was:

PciRoot(0x0)/Pci(0x1c,0x3)/Pci(0x0)
