Hi Tammy. Thanks for your prompt response. Just to clarify, I'm not having trouble connecting to Apple services. I'm getting a constant pop up asking me to sign in to Apple Media Services. I enter my password, but the prompt just keeps coming back, sometimes a few days later, sometimes a week or two. It varies.
First off, what ARE Apple Media Services?
Second, how do I stop this constant prompt?
I'm not even using Apps Store, iTunes Store, etc.
I am not on a VPN. Unfortunately, I am not able to run the machine on a different network, but in my experience, this sort of behavior is not usually network specific.
Hope this helps.
