Since I updated to DP3, everytime I boot (restart or shutdown->start), I get this error. I tried everything (SMC reset, PRAM reset, repair disk and permissions) but it didn't solve the problem. Also, handoff and continuity doesn't seem to work.
I have a early 2013 15" rMBP and an iPhone 5 with iOS 8b3.
