At least (1) has been finally fixed as of late. An "Open" button at last. I see MAS as a good entry point for novice Mac users. But Apple could do a better job at curation here. Unlike on iOS, MAS apps have a bigger responsibility with user data, since even with sandboxing you can lose files or have your data sent across the wire. Check out the reviews for countless "disk cleaner"-type apps. Seeing apps like [1] repeatedly in top 10 makes me lose faith in the review process. Macs don't need users to manually manage "free" memory. By "freeing" memory you're purging the cache and forcing the system to reload things. Hey, at least it's free. Another: seemingly dozens of poor clones of built-in apps like Preview, complete with one-star reviews. For example, [2] by a developer who published 60+ (!) apps of similar quality. Or, [3], same situation but with a $6.99 in-app-purchase. [1] https://itunes.apple.com/us/app/memory-clean/id451444120?mt=12 https://itunes.apple.com/us/app/memory-clean/id451444120?mt=...
