Pairing Jabra Elite 85H with Mac Computer

yeah, any bluetooth headset that support a2dp profile should work with all devices that also support that from computers to phones and tablets

https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Advanced_Audio_Distribution_Profile_(A2DP)

to work the headset needs to be disconnected from other devices as they can't pair when they have an active connection to another device

and then the headset needs to be placed into pairing / discovery mode

and maybe you need to choose the headset as active audio output device in the mac computers system preferences->audio
