Upgrading to BT 4.0 (Airport upgrade)
Looking to upgrade the airport card to access continuity, handoff etc.
Looking at other answers here, the only one pertaining to what I want, was posted in 2014, and since the dating of that post, I have found mentions of the possibility of this on other forums. Has anyone had any luck with upgrading? A model number for the upgrade part would help, if it’s possible.
