osx.9xbrn

I somehow ended up on the BrcmPatchRAM.kext release page again and saw the change log for version 2.7.0 saying, "Improved performance on macOS 15+ by disabling incompatible patches". That got me wondering if my card was affected. I replaced BrcmPatchRam.kext with version 2.6.9 and reset NVRAM, and my Bluetooth back. Not too sure if it’s supposed to show up as a third-party dongle, though, but at least it works. AirDrop remains limited as it started from Monterey: it only works reliably from my iPhone to my Mac. If I want to send something from my Mac to my iPhone, I actually need another iPhone nearby, set to discover others for AirDrop to work both ways.

BlueToolFixup replaces BrcmBluetoothInjector for macOS 12+. According to their docu, BlueToolFixup also supports 413c:8143 devices. Both bluetooth* NVRAM properties are from the same page. Others suggested it worked for them with DW1560 cards so I thought to give it a go, but it's doesn't work for me.

Hi, I'm trying to get Bluetooth (DW1550) working on macOS Sequoia 15.5 on my E6440. I followed Wifi in Sonoma & later: Patching for legacy Broadcom wireless cards and got WiFi working. However, BT shows up in system information but won't allow me to toggle it on from the menu bar. EFI.zip For context: - Install macOS using system product name MacBookPro15,2 - After initial device setup, reboot and reset NVRAM - Boot using system product name MacBookPro11,1 - Run OCLP to fix graphics and networks Any idea what I'm missing?
