It is possible that the serial number indicates that the item was reported as defective and Apple replaced it, but it was not returned to Apple as required, it was stolen or lost from stock, or it was damaged during shipping. You cannot change the serial number of your product.

Older Mac computers will be able to keep up with current security updates. Because each Mac is an entirely new experience, it is unique.

So, if you need to provide your Mac’s serial number for customer support or warranty purposes, you can rest assured that it won’t have changed after a software update.Īpple’s main logic boards and the rest of its product are hard-coded to keep track of serial numbers. The only time the serial number would change is if you replace the logic board or entire computer. However, the serial number itself doesn’t change. So, when you update the software, Apple’s servers register the new software version against the serial number. This registration process includes your Mac’s serial number. When you update the software on your Mac, the new software version is registered with Apple. The long answer is a bit more complicated. The short answer is: no, the Mac serial number does not change after a software update. So what’s the deal? Does the Mac serial number really change after a software update? This can be a problem if you need to provide the serial number for customer support or warranty purposes. One common issue that Mac users face is that their computer’s serial number changes after they update the software. But like any computer, they’re not perfect. Mac computers have a long-standing reputation for being more reliable and user-friendly than their PC counterparts.
