I signed out of iCloud on a mid-2015 rMBP 15" (10.10.2), but it still seems to be lurking. I've done the following: 1. Signed out of iCloud 2. Ensured that the device is removed from Find my iPhone The only thing I haven't done is format the hard drive, something I'd prefer to avoid, since it's a work computer (but will do if it's a last resort). Problem is that: 1. I'm still getting notifications on the MBP when I add/remove devices from my iCloud account. 2. Although I'm signed out of Messages, when I start up the app, it still has my iCloud email pre-filled in the app/account login window. So, is there some step I'm missing from scrubbing the MBP entirely of my iCloud account?
