I didn&#x27;t mean to offend you. I just wanted to point it out for future reference. Simmer down and learn to take a correction.<p>&gt; I suspect you think this makes you seem more intelligent<p>Nope, I&#x27;m just a Mac developer. I use OS X every day. MacOS was non-Unix operating system that ran on a PowerPC architecture. You were very far off<p>&gt; it makes you seem socially inept<p>If you called Windows 10, Windows XP it would not be socially inept to correct you <i></i>unless you were not in the tech industry. However, since this is HN, I assumed you could handle it. Sorry!
