Purely from a user&#x27;s perspective, the Mac app store has a considerable advantage in centrally managing updates. Non-MAS apps each have their own eclectic ways of updating. Some support automatic update checks, while users have to explicitly check others.  For the ones with automatic updates, there are a number of ways it&#x27;s handled.  Users don&#x27;t generally want scores of update daemons running, and the whole business of &quot;On launch, check for update, notify the user and let them choose whether to update now&quot; really feels like the web page pop-ups that are so popular. (&quot;I launched the app to do work, not to see if there was an update.  The update prompt is in my way.&quot;)  This cries out for a better user experience.
