Ok call me dumb but I have been playing macOS FPS games for over 10 years and I've never been completely stumped like I am with this one: Having played the GOTY first edition Borderlands from the Mac App Store I naturally craved more and moved on to Borderlands 2 followed by the Pre Sequel edition . Having completed them I understandably wanted more and failing any alternative that I had not already played I looked at the Add-Ons selection. There was not much that interested me in the pre sequel so I downloaded Borderlands 2 again from the purchases section of the App Store. I then purchased the Ultimate Vault Hunter Upgrade Packs 1 & 2 extending the game to 72 levels. Now I'm confused, how do I play them? Do I have to play the whole game through from the beginning to get to the added levels? How can I know if the in app purchases have been applied? In the Start Up Panel under In App Purchases tab I see the two packs have a tick on them and there is a progress bar that reads 14% installed. If that's all there is to it then I guess I just have to work my way to the end of the game and wait to see what happens. I accept that uninstalling the game was probably as mistake. If I had bought the add-ons at the finish of the game I would have known straight away. I don't really mind playing the whole game again just would hate to get to the end and find the in app purchases hadn't been applied.
