For the first time, I didn't have any questions for my trainer. But, I went anyway, to learn anything new.

First, I asked my trainer to walk me through the rest under "System Preferences." He was knowledgeable. When it's done, I still had five minutes left. So, I asked him to show me a trick. He thought about it, and told me this: "You pay 30% more for your MacBook (than a desk top), because of the battery. So, use it." I said I know this, from my son's experience. If one plugs in his MacBook all the time, the battery loses its capacity. So, my Mac friends, go ahead and use your battery. You don't need to drain it completely all the time; just once a month will do.

Happy Mac-around!
