Ipad shows up in sidebar on MacBook Pro but not available
When I plug the iPad Pro into the MacBook it shows up in the side bar but when I click on it I see the "trust" button for about second and then it disappears. I also notice that the battery icon on the iPad constantly changes between charging and not charging. What the heck is going on? I'm trying to update the software via the MacBook because "Media" and "other" have eaten up all of my space and I cannot find what that is exactly. Thanks in advance.
