Are you annoyed with podcasts bookkeeper sync keeps popping up on your Mac? Well I’m. It doesn’t matter how many times you click on Cancel button it keeps popping up over and over again. The pop up message (see the image below) keeps popping up five to six time in a row and I can not get rid of it.

Here it is how to turn off “Sign in to Podcasts” “Podcasts Bookkeeper sync on Macbook Pro.
The easiest solution is log into with a same Apple ID in the iTunes app on the Computer / Mac you’re using.
If you are logged in just Log Off and Log In back into the iTunes Store.

I wouldn’t suggest to change any Preferences setting in a Keychain Access like some one suggested, it could make a lot of damage. If you do, I recommend to back up your MacBook with a Time Machine before attempting to change any settings.
Thank you
