What Bluetooth profiles does my MacBook have?

Hello,

I have (had) JBL Everest 150NC headphones that did not work correctly with my MacBook Pro (2017); after connecting, the headphones would crash and turn off unexpectedly (without warning).

JBL simply stated they did not develop their products for MacBook (although they do for iOS), and suggested the (Bluetooth) AVRCP-profile on my MacBook might be the cause.

I cannot find any information on what AVRCP-profile version my MacBook has, or which Bluetooth profiles at all, other than those for iOS.

What Bluetooth profiles does my MacBook, running macOS 10.14.5, have or where can I find this?

Specifically, which AVRCP-profile?

Kind regards,

Isaiah
