Hello all! I don't post here much, but I'm having an issue with the beta and I cannot update my system! So the App Store says I have an update to Beta 7 available. I tell it to install and it says that it's going to restart. After the countdown, it says that "Available updates have changed" and sends me back to the app store, where the same update is waiting to be installed. Clicking install just sends me on this same loop over and over again. I'm running a mid-2014 rMBP 15" if that's any help at all. Any ideas? Thanks!
