If you have your product's original packaging, you can check the barcode to find the serial number. You can also find your product's serial number on the original product receipt or invoice. Or choose a product below for details about finding the serial number.
But if you ever need to use your warranty and have Apple repair your Mac, you'll need that serial number. And if your computer is ever lost or stolen, the police will care about the serial number too.
my thoughts mac serial number
The easiest way to find a Mac's serial number is to click the Apple logo at the top left corner of the screen, then click About This Mac. You'll find the serial number in the "Overview" tab of the window that opens.
If your computer is turned off or won't turn on, you can flip your Mac over and find the serial number physically printed on the hardware. Look for the text beginning with "Designed by Apple in California," and then look at the lowest line of writing, where you'll find the serial number.
The display damage may cause hardware test errors, so record any error numbers you see. You can make the hardware tests 'loop' by hitting cmd+L. Run the extended & standard tests a few times to see if everything is OK.
The DATEVALUE function converts a date that is stored as text to a serial number that Excel recognizes as a date. For example, the formula =DATEVALUE("1/1/2008") returns 39448, the serial number of the date 1/1/2008. Remember, though, that your computer's system date setting may cause the results of a DATEVALUE function to vary from this example
Excel stores dates as sequential serial numbers so that they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,447 days after January 1, 1900.
