Apple just delivered a small but welcome tweak to the Mac App Store: a window that pops up when you click “Purchase” next to an app, asking you to confirm your decision.
Depending on whether or not, like me, you’ve accidentally bought a $50 piece of software on the Mac App Store through the errant click, you’ll find this either a welcome prophylactic against your own casual stupidity, or an irritant that doubles the clicking required to actually get the app you want.
Unfortunately, if it’s the latter for you, the Mac App Store doesn’t allow you to toggle the purchase confirmation off, as in the iOS App Store, so you’ll just have to live with the redundancy for now.
