That sounds logical. I'm curious to know Apple's reasoning behind this.
I first realised that when I tried to change the icons of the new App Store apps, and the new icons would not take. File permissions are not the same as the other apps.
So what do you guys think about temporarily changing the file permissions and then resetting it? Would that be okay?
