Asfand Yr Posted March 11, 2023 Share Posted March 11, 2023 Hi there, need some help. System Info: Dell latitude E5470 i5 6440HQ ram 16gb Graphics intel HD 530 network card: intel dual band AC 8260 w/bluetooth So I have macOS Monterey installed; using it for a while now. Bluetooth wasn't working so i wanting to fix that and I used BlueToolFix and IntelbluetoothFirmware kexts. It worked actually pretty but after a few hours, I restarted my pc and bluetooth stopped working again. I did some twikling again and added IntelBluetoothPatcher kext after which bluetooth started working again. After restarting the PC, bluetooth stopped working again. Now the problem is that it's just not working in Monterey, it's not working in Windows either; the Bluetooth device is not even detected. I have tried everything I could so far and last resort is asking for help here. I'd appreciate if anyone can help me fix this. I am willing to provide more info if you need any.

Administrators Hervé Posted March 11, 2023 Administrators Share Posted March 11, 2023 -> Thread moved to relevant hardware support section; this is not a thread about hardware information. Please make every effort to post in the appropriate forum sections and to use punctuation, not just post in a single extended sequence of words! This is totally unreadable and such posts/threads be deleted without prior notice in the event of re-occurence. Assuming you've followed all the necessary recommendations posted at ITLWM, you can always try and re-apply the Windows driver for the card in the hope that it'll reload the firmware onto the card if that's what's gone sideways. But you may have to consider that the card is either suffering from a bad connection (try and clean the cards connector and the slot) or simply got defective (it happens). Check if the Bluetooth module is seen or not in SysInfo->Hardware->USB. If it's not, as per in Windows, you have a hardware-related issue. it's probably not the case but do check that Bluetooth did not get somehow disabled in BIOS settings.
