About the serial number of the refurbished machine
1. The information obtained by searching the serial number of refurbished machines on the Internet is usually different from that given by the seller;
2. If the query result is "Sorry, this is the serial number of the replacement product", then this machine is a refurbished machine, repaired and the motherboard has been replaced. Usually, the serial number of this machine will be officially cancelled.
3. Pay attention to the warranty time, purchase place and other information in the obtained information. If the item "Last Activation Time" is displayed, it can be directly determined that it is second-hand, and the new machine will not be excited by itself (see)!
4. The refurbished machine is also official, the serial number starts with 5K, and the warranty is only three months. (PS: 5K starts with a return resale machine and a service machine). This shows that the serial number is so important! Therefore, when identifying refurbished machines, it is necessary not only to look at the appearance, but more importantly to look at the serial number! You can check the serial number information in "Apple 100" or Apple official website.
