How can I use bluetooth on my Windows 10 guest machine using my built-in macOS Bluetooth chip.

When I try adding it as a USB device it come up with

Failed to attach USB device Apple Inc. Bluetooth USB Host Controller [0150] to the Virtual Machine Windows VM

Details

Could not find USB Device with uuid {164bc863-a9e1-4f47-b389-36afadb8c6d5}

Edit 1:

Aftersome futher reasearch I found out that it will work if I am able to the the Bluetooth host service/daemom. How can I do this?

Edit 2: Also found that Parrallels desktop is able to use built in bluetooth without you needing to do anything. This proves it is possible to use Built in Bluetooth on a VM. How can you achieve this in VirtualBox?

General Machine Info

OS:macOS Catalina (10.15.3)

Computer 2015 Macbook Air

Any solution to try and fix this would be greatly appreciated as I have been trying to get this to work for a few hours

The problem with this, is that the host (your Mac) needs to completely release the Bluetooth adapter so that VBox can take “ownership” of it.

To see what’s loaded issue the command.

kextstatus | grep -i bluet

All of those kexts need to be unloaded. The problem is, macOS will respawn the processes automatically.

There’s a couple options you can try:

  • use a seperate USB Bluetooth adapter
  • Use a different host OS (FreeBSD can do this) that will allow you to manually load/unload support dor different divices.

macOS, especially with all of the new protections implemented in Catalina won’t allow you to do this.

  • Is there anyway to unload this kexts permenantly (eg. moving their plists to a different location and restarting?) – Roxiun May 16 at 2:10
  • Not that I know of. Even if you do remove it by disabling SIP, the very next update reinstalls and reactivates it. What is your specific use case? Maybe we can find an alternate solution. – Allan May 16 at 4:06
  • Parallels desktop is able to use built-in bluetooth on a Windows VM. I just want want to be able to connect & use Bluetooth from a VM. Is there anyway to achieve this functionality on VirtualBox – Roxiun Jun 4 at 13:03
