Hi Folks, New to the forum, and new to Mac after a lifetime of PC's. I just got a Mac Air 13", mid-2013 model. I have some questions about this machine and/or Mac in general, and I'm sure I'll have more. First question: I am using Safari as my browser, and have just experimented this evening with Firefox. (I've only ever used Internet Explorer in the past). With both browsers, I notice that the menu bar at the top of the screen disappears from time to time depending on what I'm doing. (By menu bar, I mean the very top line that has 'file', 'edit', 'view', 'bookmarks', etc, plus the time and date and battery icons.) I can make it re-appear if I hold the cursor up there, or perhaps change screens/programs, but is there any way I can keep it up there all the time? I don't want to keep looking for it each time I want to know what time it is or do something from the menu. The problem seems worse in Firefox, for what's it worth. (Meaning it disappears more often -- like for instance, right now it's nowhere to be seen as I type this).
