OK, so I got the upgrade bug as soon as I bought my cMP 5,1 8 core. I bought the upgraded Wifi/Bluetooth card recommended on here and my system sees it. Both the Wifi and Bluetooth work fine but I can't seem to get Handoff/Continuity to work. The System Profiler shows the new card as being Handoff compatible. Handoff is turned on on both my Mac and my iPhone X. Both devices have Bluetooth turned on. Both devices have Wifi turned on and connected to the same network. I tried signing out of iCloud on both devices and back in (boy, that was a horrible experience on the phone - I had to add all the card in my wallet back). I can't think of anything else to try. The Bluetooth menu on the Mac shows the iPhone isn't connected to the Mac, but I can connect it by selecting it. Strangely, it doesn't say 'Connect' like all my other devices do. Instead, it says 'Connect to Network'. I'm assuming that's so it can be used as a hotspot? Does anyone have any ideas so I can move on to my next upgrade?
