About This Mac

Here's some very good information that could help you out in the long-run. It's basic, but EVERYONE who owns a Mac should know about the About This Mac window. This window will give you all the information you'll ever need to know about your computer. If you have any problems with your computer and you call AppleCare or a technician, telling them you have a Macintosh or an OS X computer tells them nothing. This window will be able to tell you the System version, the amount of RAM, speed, and type of computer you have.

Version
When the window comes up you will see a number of things. From the top down:
This computer is running Mac OS X (Operating System 10)
The version number is 10.6.3 (Known as SnowLeopard)
The software update button (we'll get to this later)
The processor is 3.06 Ghz Intel Core 2 Duo
The memory (or RAM) is 4 GB
The startup Disk (or the name of where the computer runs it's Operating System).
Finally, The More Info... button (we'll get to this later, too)

Build
Click on where it says Version and it will change to Build. The Build number is only useful for the technicians. 
5
Serial Number
Click on Build and it will change to Serial number. This is very important if you have to get the computer repaired. This WILL be something the technicians will want to get from you.

Software Update
If you click the Software Update... button, it will launch the Software Update System Preference that will check with Apple's servers to see if you need any system software updates. These are free updates from Apple for software that runs your computer. This will NOT, I repeat not, update anything other than the system software. So if you have Adobe Photoshop or Creative Suite, this program won't update that.

Profiler
If you click More Info... button, you'll launch a program called Profiler. This will tell you, in detail, everything about your computer. Above, is the first page that comes up when you click that button. You can see everything from the model of the computer, processor name, speed, number of processors and cores. Even the serial number. To the left, you can see a window with other items. These are other areas where you can get information about the computer. If you have a laptop, the Power items will tell you about the battery health. If you want to know if your computer can burn a DVD, check the Disc Burning item.
