This matches everything I&#x27;ve read from Mac developers – the App Store would be a great idea except for the arbitrary impediments to having a viable business.<p>Michael Tsai had a good roundup of just how widespread that trend&#x27;s becoming and how it&#x27;s driven by only a few issues like the inability to do paid upgrades and the slow review process:<p><a href="http:&#x2F;&#x2F;mjtsai.com&#x2F;blog&#x2F;2015&#x2F;12&#x2F;01&#x2F;sketch-leaving-the-mac-app-store&#x2F;" rel="nofollow">http:&#x2F;&#x2F;mjtsai.com&#x2F;blog&#x2F;2015&#x2F;12&#x2F;01&#x2F;sketch-leaving-the-mac-app...</a><p>I really wish the Mac App Store was more like Yum&#x2F;APT where you have a single update mechanism with baked-in mandatory security but otherwise leave publishing up to the actual developers. If Apple wants to have a curated store with reviews, etc. that&#x27;s fine but it&#x27;s just not viable as the only option for every class of application.
