Mac App Store not loading

Same problem here. Mac Book Pro Mid 2012 with Yosemite 10.10.3

And no iTunes 12.2 upgrade available! This is very strange!

Family sharing's app on any device also doesn't work. (Macbook air 2013 - Yosemite 10.10.4 & iPhone 6 - iOS 8.4)

same issue. app store doesn't load. can't update to itunes 12.2. Macbook pro running yosemite 10.10.3

I am experiencing the same issue as well, have been since about midnight. Not sure what is going on either.

Same issue. I went to the downloads section on the apple store and downloaded the file directly from the website so I can update my Macbook Pro 15"

Same issue here.

Thanks for the tip regarding just downloading iTunes!

Same thing here. MacBook Pro Retina mid-2012. When I go to "Updates" the spinning wheel kicks in and never stops. :-(

If I download iTunes 12.2 from the website or downloads section, once I install it will I still have all of my iTunes files?

Same problem here. Mac Book Pro Mid 2012 with Yosemite 10.10.3

When I go to "Updates" the spinning wheel kicks in and never stops.

Could we have an answer from the Apple Support Communities team, please!

The updates that the App Store found that I needed have now kicked in and ARE UPDATING! One of them is iMovie, a biggie, so I'll still have to wait awhile to see if I can get the iTunes update. Just before updating began working, after the spinning wheel had been spinning for about an hour or so, I received an error message saying a "Helper" could not be communicated with, or something of the sort (I probably should have screen captured it). :-(

Same here. I have a MBA with Yosemite 10.10.3... 😕

Same here too on my iMac

I am having the same issue on my MacBook Pro. Yosemite 10.10.4
