So I got my first MBP and I'm transitioning from a lifetime of Windows usage to the Mac OS. It's a little rough and I'm a little confused on a few things. 1. For starters, what's the difference between the launchpad and the desktop? Why are certain apps designated for Launchpad while others (coconutbattery and appcleaner) can't be placed in there? So far, this has been the biggest source of confusion for me -- The managing of Launchpad, desktop, and the dock. 2. What's the difference between downloading an app online (i.e., coconutbattery online) as opposed to downloading something off of the appstore? Do appstore apps download to a different place on the computer or something? 3. What would be the "My Computers" equivalent to the Mac? In other words, how can I get to the Mac equivalent of C:\Program Files\ or C:\System32? 4. Is there anyway to swap the Apple/command key with the control key? I'm used to Ctrl + C (and other Ctrl commands) as opposed to the awkward hand positioning for Command + C. 5. Is there a website with a simple chart that shows the Apple equivalent shortcut to Windows shortcut? For example, Ctrl + Alt + Del/ESC is more or less Command + Option + ESC for the Mac, as well as F5 on Windows is Command + R.
