Before my High sierra upgrade, my 5,1 had the full feature list of continuity, airdrop, Auto Unlock via Apple Watch, Instant hotspot, ETC. After High Sierra, those features are mostly all gone except for airdrop which currently works. Continuity is also working partly, as I can receive calls on the 5,1 but cannot handoff, app states or webpages etc. I have thought maybe I need to run CAT again but when I do, it states that the features are already active. Maybe something with the updated SIP? Bottom line: has anybody gotten Cat to run properly on High Sierra? There are some discussions on the topic the Git page, and around some googles searches but nothing concrete.
