List of hidden OS X features, tips and tricks
Not a hidden feature - but what confuses some of my family members is that if they install an app in OS X, they click on a downloaded dmg (or it auto-opens), and they get this Finder window opening, without "Applications" visible.<p>Initially they just ran the application like this, as if it was installed.<p>However, I've explained that it needs to be moved to "Applications".  This is difficult, seeing that if one clicks on Finder again, it doesn't bring up a new window.<p>I tell them to do File->New Finder Window, but I wish there was a more elegant solution to this.
