Unable to sign to my iCloud account

So this looks like it was related to iTunes. I ended up logging out of Apple Music/iTunes/App Store, logging back in, and the issue went away.

Same problem. I logged out and shut down my computer and it was ok for a week. Now it's back. I'm also getting all notifications that my other devices (phone, watch) are now connected to this account when they have always been connected. Seems like Apple can't cope with customers owning multiple devices anymore...

Thanks for this! I just did what you said about logging out and logging back in, and the issue is resolved.

I can't even work today. I'm 2.5 hours into the day and it has popped up at least 10 times! There is no way I can find to report to Apple. My iCloud mail was inactive 3 hours yesterday, so I lost everything... even going to iCloud.com.

Same here! I have tried clicking both options and nothing works. Keeps popping up every couple of minutes. I restarted and it's still happening. The only thing I see is that there is an update 14.3.1 that I will try to install and see if that helps.

Why isn't there more online about this?? We can't be the only people this is happening to.

I am having the same issue. It started on my Macbook and now on my iMac.... every 10 minutes no matter what I choose or if I close the dialogue box. The weird thing is that my iCloud icon has changed too... only in the lockscreen setting... it's really annoying... I have finals and papers to write and it keeps popping up everywhere...

This is happening to me too and nothing above is working! I don't even have itunes subscription so logging in and out is not an option for me, as far as I know but I'm not really a MAC person so half the stuff on this PC is foreign to me. All I know is I find MAC so frustrating compared to PCs...

This is happening to me after I changed my password as well. Any solution?

Hi, I tried this (signing into Apple Music) but am still getting the pop ups. Has anyone had luck finding another work around?

Thanks

why is this happening? Does anyone know? I got a request to update/change my apple id password which i did and now I get this message A LOT and the password change isn't synching

I closed iTunes and it is still popping up as always

Same here. Just started today. Pops up every few minutes. I *did* change my account password yesterday, coincidentally. I'm curious if it's related to that (and everyone else here happened to also change their password yesterday), or if it's unrelated.

All said, no clue how to get it to stop. I've tried clicking "Use <account>" and "Use another account", and neither seem to help.
