I suppose every operating system is going to have little problems like that, and if that&#x27;s all there is, I can manage. It&#x27;s just that I really liked OS X back in the Leopard and Snow Leopard days. I could almost describe it as a &quot;magical&quot; experience using them, but I&#x27;m worried that that magic&#x27;s gone in these latest versions, as all this recent complaining seems to indicate.<p>Can you perhaps tell me how newer versions of OS X fare as a UNIX-based operating system for development, compared to Linux? I&#x27;ve heard that it&#x27;s become more locked down. How about its app &quot;ecosystem&quot;? I remember that a lot of apps, by developers small and large, were of really high quality.
