It is important to know the identification of your Mac and your PC when upgrading software or hardware, or when warranty work needs to be done. Even though this is perhaps more important for Mac owners, you should know these important details about your PC, too.
Whenever you need to perform work on your Mac, especially as it relates to reinstalling the operating system or determining its serial number, you can easily find this information.
First, select the Apple menu and then select About This Mac. In the box that opens, select the Overview tab at the top if it isn’t already selected. Here it will clearly state your currently installed operating system, the model of your machine and the date it was released.
For example, if you have a MacBook Pro that is several years old, it may state something like this: MacOS High Sierra, MacBook Pro (13-inch, Mid 2012). It will also indicate your processor speed, the amount of memory installed, your graphics (video) component and finally, your serial number.
If you have work done on your Mac, it is important you have your serial number available. This can be a little tricky if your hard drive ever fails, so I recommend that once you have this information on your screen, you can take a screenshot of this by pressing Command + Shift + 3. A picture of your entire desktop, including your computer info, will be saved to your desktop in a PNG picture file format named “Screen Shot” with the date and time it was taken. You can then open your email and send this screenshot as an attachment to yourself, so you will have access to your Mac’s information when you need it. Put “Mac Info” or something similar in the email’s subject line and it makes it a snap to find later.
To find this same information about your PC, open your Control Panel and click “System.” When the window opens, you’ll see at the top, your currently installed operating system and below, under the System section, you’ll see the manufacturer and model of your PC, your processor and installed memory, and your system type, whether it is a 32 or 64-bit system.
To make a screenshot of this information, simply press the screenshot button on the top row keys on your keyboard (on some models you will also need to use the function key at the same time) and then open your Paint program and paste (Control + V keys) it into Paint. Once it shows up in Paint, click “File” at the top-left and then “Save As” and save it to your desktop. You will then be able to email it to yourself, so you have the information easily accessible.
