Apple Mac OS X daily tip 010: view the version, version number, and serial number of the Local Machine

First, let me tell you the truth. I called Apple customer service to ask about this technique.

When you call Apple customer service for the first time, you will first register your account. One step is to tell him the serial number of the machine.

I asked him how to check his serial number.

Customer Service tell me

Click the apple icon in the upper left corner.

In the pop-up window, there is a version 10. x. x"

Click this line to switch to the version number and serial number respectively"

By the way, Apple's Chinese customer service seems to be in Singapore, and the service quality is okay.

At the beginning of registration, you will be asked about the purchase date as late as possible because the free customer service time is calculated based on the purchase date + N months.
