Mac Must Knows

Having a stack of CDs for different programs and games is fine, but what if you could put them all on your computer...

Wouldn't you rather just double-click a file instead of looking for a CD then putting it in?

It's actually quite easy to put all your CDs onto your computer. The information is saved in a .DMG (Disk Image) file which is like a virtual CD.

To do this all you have to do is:

1. Put the CD into the disk drive.
2. Open up Disk Utility (Applications > Utilities > Disk Utility).
3. Select the CD you inserted in the right-hand menu.
4. Click New Image.

And your done. The CD is converted to a .DMG file and saved on your computer.

Now whenever you want to run that CD you just click on the file.

Easy!

Programs can also be guilty of sucking up the power.

How can you find out which ones?

With Activity Monitor. It comes with Mac and can tell you everything you need to know about the applications running.

Activity Monitor says how much CPU, RAM and Virtual Memory your applications are using and more. You can use it to see which programs are slowing things down.

Checking activity monitor every once and a while can give you insight into which applications are holding back your computer.
