Master the Art of Screenshots - Mac OS X

Mac Screenshots

Having a screenshot of something you see on your Mac can sometimes be priceless, especially if something happens that you want to show someone else, or if you want to email someone a picture of how to do something on their Macs. Fortunately, Mac OS X has a ton of options for taking pictures of the screen, or even individual elements of the screen. We'll get into the basics, and we'll also show you some advanced techniques that many 'power-users' may not know of (yet).

Dealing with Locked Files on a Mac

Quite often, I am asked one of two related questions: 1) "Why can't I delete this pesky file? My Mac says the file is locked, and I can't delete it unless I do something special!" or 2) "Gaa! I can't copy <insert name here> to my flash drive or another hard drive because it's locked—help!"

Well, I will answer those questions, and much more, after the break.

Laptop Temperatures: What's safe? How do I avoid overheating?

A question oft asked on the Apple Discussion boards (and other online computing forums) is: "My laptop seems really hot on the bottom* - is this safe?" This page will attempt to answer this and many other questions about iBook temperature concerns.

Why is it important to control (to a certain extent) your computer's temperature? Because a computer is like a car: if it's too cold, it won't run, and if it's too hot, it will overheat. As with all physical objects, a computer must obey the laws of physics, and when the temperature is too high or too low, things inside the computer won't work well. The optimal operating temperatures for your specific computer should be listed in the computer's manual.

Temperature Monitoring Software

There are many free software programs to help you monitor your Mac's temperature (whatever model it may be). My favorite is Temperature Monitor (free). Temperature Monitor allows you to see all temperature sensors in windows, the Dock, the menubar, or your Dashboard.
