I'm beginning to feel worried about how much it takes to install recent Xcode updates. An hour ago, I clicked on the "update" button for Xcode 7.1.1 in App Store. It spent about 30 minutes waiting, and then another 30 minutes installing (and has not finished yet)... is this normal? I've been developing on Mac since Tiger, and Xcode updates have always been a matter of a few minutes... are you experiencing these times too, or is there anything wrong with my iMac?
