verification Failed - this action cannot be completed

I experienced the same problem on my MacBook Pro. I found a solution on the Apple Stackexchange that worked for me:

Execute the following commands in Terminal:

sudo mkdir -p /Users/Shared sudo chown root:wheel /Users/Shared sudo chmod -R 1777 /Users/Shared

I did this and my problem was solved.

I had similar issue where I discovered missing shared folder in /Users. Adding a shared folder resolved my issue. Similar to above solution, here’s more detail to reproduce solution if it applies to anyone else:

- Finder > Go > Go to Folder

- enter /Users :: Go

- if no Shared folder, open Terminal to create one in /User

- Enter commands in Terminal (must be logging in as user with admin access):

- sudo mkdir -p /Users/Shared

- sudo chmod 1777 /Users/Shared/

- reboot and see if can now login to iCloud

I am having the same problem with iTunes on Windows 10 PC. It works fine on my idevices but not iTunes on the PC. Tried everything I can think of and suggestions from other posts. Tried to contact Apple help and they didn't help at all. I'm at a loss and getting very frustrated!

OK, so this worked for me also finally. What's up with Apple not moving this up or even providing more recommendation to solve this issue that's plagued me for months - that's all infuriating.

but this answer:

http://apple.stackexchange.com/questions/235957/after-el-capitan-update-i-cannot -sign-in-to-anything-with-my-apple-id-th…

which someone else also suggested but I had to go to page to get the real answer (the short cut command this person constructed didn't work) was the only way to get through...

This answer was the solution that worked for me:

sudo mkdir -p /Users/Shared
sudo chown root:wheel /Users/Shared
sudo chmod -R 1777 /Users/Shared

i had the same error.

After talking to Apple Support we found out my account was blocked.

Try id.apple.com and start the password reset process. It will tell you if your account is blocked and if it is you can unblock it with clicking on a link in an email or answering your security questions.

Good luck!

I have the same problem. but my problem happened after I unblock and reset my account. no any clue how to solve it?

I was able to change my password. Didn't affect anything. Any other tips?

I had this same error message when attempting to sign in to iCloud on my new phone. I logged into Apple ID (applied.apple.com) on a different device and turned off my two-step verification in "security" tab. After that I was able to login on the new phone no problem.

I can sign into my account fine online at id.apple.com. I don't think my account is blocked. I'm having this issue in the latest iTunes version on Windows. Any other ideas?

Tried this, didn't solve my problem. Thanks for the tip

I'm having the same exact issue. Just randomly started tonight too. Please post on here if you figure anything out

This is happening to me too. Really annoying. I have reset password multiple times. Any idea what to do??

Okay this is getting really annoying now.

it keeps asking me to verify my Apple ID every four minutes and I am not pleased.

Same thing is happening to me

Have you tried updating to iOS 10.2.1?
