iCloud keeps asking for password

I have the same thing, every time I launch Mac Mail, I get prompted for the my iCloud password. After I enter it, Mail retrieves the mail properly.

I had this same issue and fixed it using the following steps:

1. Close the Mail application

2. Open System Preferences > iCloud

3. Uncheck the 'Mail' checkbox

4. Recheck the 'Mail' checkbox

5. Open the Mail application

That solved the issue for me.

Thank you sketchnet. That worked for me also.

Thanks a lot! It worked for me too 🙂

Thanks sketchnet, this worked for me as well!!!

Can't find the linke to show this worked for me to give you points though....:-(

THX!!! this worked for me as well.

;-)

worked for me too! thanks!

Thanks for the help! My husband was having problems and this worked for him.

Thanks sketchnet. Worked.

So far, this is the only bug on Mavericks.... except Mail crashed a few times. Maybe because of this same iCloud bug.

But, this morning, Mail doesn't have the right "sent" email and the same in Safari's iCloud Mail page.

Argh ! The "sent" folder has a bunch of old deleted emails and I can't find my important messages.

Unacceptable Apple.

Thanks very much Sketchnet!

My issue started originally in OSX 8.5 and then got more frequent after Mavericks. It affected Mail and also Notes.

Thanks sketchnet; your solution worked for me; after hours messing with keychains & passwords...

Thanks Sketchnet, worked for me too. Nice one, 🙂

Thanks that worked. I also could not delete my iCloud mail and it worked for that also. Wjat a pain that was. Thanks again.
