Knowing the serial number of your Mac can be very useful in several cases, in particular to check the warranty status, check the characteristics of your computer or to check its model if you buy it second-hand.
It is not always easy to know where to look for this famous serial number. On the object itself, you can see many symbols, without knowing exactly which ones make up the serial number of the Mac.
Fortunately, Apple offers several options to find this identification number. A good thing when the Mac doesn't turn on any more or the number on the object has been erased.
From the system
If you still have your Mac and it works, then you can check your Mac's serial number from the desktop. To do this, go to the Apple menu on your computer, in the upper left corner of your left of your screen and select About this Mac.
On the new window, you can find several interesting information about the Mac, including its name, model, the version of the operating system installed, as well as its serial number. This is made up of 12 signs.
From the settings
Another solution: consult the System Information application. To do this, go to the Applications folder, then Utilities and select the Hardware tab. The serial number will be shown on the right page.
On the object itself
If your computer is not working or you are unable to access the system for the moon or some other reason, you can always turn to the information on your Mac. The serial number should be listed above, whether it is a Mac, MacBook Air or Pro. You just have to find it.
Your Mac's serial number can also be found on the computer's original box, as well as on the invoice. Last solution: connect to the Apple website and search for your device. Just click on the Mac you are interested in to access its information.
