MAC Retrofit Machine Identification skills

First, start with the appearance

1 to distinguish whether a MacBook notebook is a refurbished machine, you can start with its appearance. From the entire fuselage, screen, keyboard, to see if there are scratches, appearance damage and so on.

2. You can also check the screws at the bottom of the notebook to see if there are any traces that have been twisted.

3, if the bottom of the screw has been clearly twisted traces, it means that the machine must be refurbished. If the appearance of the notebook is not a problem and the screws have not been twisted, please look down.

Second, view battery usage information

1, because the MacBook Pro or Air will be built into a battery, the use of the process will often charge the battery, and the battery has forgotten function. We can look at how many times the battery has been used, and start here to see if the current notebook is a refurbished machine. After entering the MAC system, click on the Apple icon in the upper left corner of the screen, then click on the "about this computer" option, as shown in the figure

2. Click the "System Report" button in the About this machine information window, as shown in the figure

3. Next, click on the "Power" option in the left column of the System Report window, as shown in the figure

4, then in the battery information in the performance information see "Cycle times", here you can see that I used to have more than half a year of the number of cycles of 152 times, as shown in the figure

5, if it is a new MacBook notebook, then this battery cycle times should be no more than 10 times. If there are too many cycles, the instructions are used.

Third, from the Apple website to view the serial number

1, in addition to the above two methods, we can also use the MacBook itself to query the serial number. It is recommended that you look at the machine's serial number through the bottom of the MacBook notebook, find the Serial serial number at the bottom, followed by the serial number.

2, then please open the Apple website of the Machine Serial number query page address: https://selfsolve.apple.com/agreementWarrantyDynamic.do?

3. Enter the serial number you see on the back of the machine, as shown in the figure

4, then can see the current machine repair and service warranty, there is an estimated due date, it can be calculated according to its factory date. This date is reduced by one year, that is, the factory date of this machine. This will let you know whether the current machine is a refurbished machine, if the current date with a large number of days, it means that the machine is a refurbished machine.
