I have reviewed the askdifferent question here: "This Apple ID is valid but is not an iCloud account" - I hate to open a new question on this topic, but none of the answers or suggestions have worked for me.

I can login to iCloud.com using the ID and can access mail, etc. with no problems. I have tried logging into iCloud in System Preferences and I get the error in the title. I have tried adding the iCloud ID to the user in "Users and Groups" and also without the iCloud ID there and I get the same error. I have rebooted multiple times. I have applied all available security updates to the system.

I have run out of things to try... System information is shown below.

I've heard of this problem, but there's multiple reasons it can occur (e.g. A recent password change, using a Hackintosh system, a corrupted OS X installation, etc).

I checked the other post you referenced and one obvious solution not mentioned was to reset your PRAM/NVRAM.

To do this:

  • Shut down your computer completely
  • Switch it back on and quickly press and hold the CommandOptionPR keys until you hear the startup chime a second time.
  • Let go of the keys and let your Mac startup normally

Note: When you log back in you may need to readjust some of your system preferences (e.g. mouse speed, time and date/timezone, etc).

  • Thanks for your suggestion. This is my mother's old macbook and I'll have to talk her through the reset (can't do it with remote desktop). I'll report back the results. – Steve H. Oct 26 '16 at 20:34
  • OK, had her do the pram reset and still the same result logging into iCloud. I know the reset worked since she remarked at how loud the chime sound was than normal. Unfortunately, I'm stuck again :( – Steve H. Oct 26 '16 at 21:20
  • Ok, so is there anything your mum can think of that may coincide with this issue? Did she change a password? Did she update OS X Mavericks recently? Anything else she can think of? Also, it's not clear from your question, was she able to log in previously on the MacBook Pro? – Monomeeth Oct 27 '16 at 0:02
