This is the problem I, as a newbie, have:
Macbook on Intel, soldered off bluetooth module, there is a usb dongle to work bluetooth. How to make an external usb bluetooth adapter work instead of the main one, if the second is not?
I know about setting NVRAM variable – bluetoothHostControllerSwitchBehavior=always.
I’m sure that with it, when the internal one is working, it works in such a way that it sees the external one as the primary and not as a “helper”.
But this method, as far as I have read, is suitable when the internal bluetooth adapter works at least somehow, because macOS strictly counts on the presence of the built-in adapter.
But when there is a physical defect, or lack of it, as I have, it does not solve the problem. It was also tested in practice – it doesn’t work. Perhaps I did something wrong and learned something wrong, please, please help to expand knowledge!
Is there a universal way at all? Without being tied to a specific one, like Broadcom. One that will always work if there is a serviceable external one. Need any way, may have to use ACPI patching?
I realize that it can usually be replaced. It’s just a matter of understanding this situation. How to use the external instead of the internal when it is soldered off!!!. What are some universal ways for the latest operating systems on intel. What exactly are they, if any.
I would just like to know the direction in which direction to move to study this issue.
Update:
As far as I know, the mac, when it turns on, turns on, it goes through all its nodes, gives a command and waits for a response. If one of the nodes doesn’t respond at startup, then when it starts up, that node doesn’t work, and there’s nothing you can do to make it work.
Maybe there is a command that turns off the check of all nodes on the Mac board?
