What to do before buying a used MacBook

Check the serial number

Asking the serial number of a used MacBook is the first thing to do because it can give you very important information about the computer. You can check it by clicking on the Apple logo at the top left of the MacBook and choosing About this Mac. You can also check it at the bottom of the Mac. What to do after getting the serial number?

  1. First, make sure the serial number on your Mac is the same as what you find in the box.
  2. Go to https://checkcoverage.apple.com/ and enter the serial number.
  3. Here you get information about the actual age of the machine, the date of purchase of the product, the warranty status, etc.

If you buy the MacBook online and the seller refuses to give you the serial number, cancel it immediately, as it could be a stolen MacBook.

Check physical damage

Check if your MacBook case has physical damage such as a bump, scratches, etc. Also make sure there are no loose screws and ask if the Mac has already been repaired by an unauthorized repairer. Next, test all ports, the optical drive, WiFi and the webcam. If you notice material damage, you can ask the seller to reduce the price.

Check the state of the battery

Replacing the battery for Apple laptops can cost you around $ 100,200. This is why it is very important to check the condition of the battery. To check it, click the Apple logo, press the Option key, then select System Information. In the left sidebar of the popup window, find Power and click it. Here you will find the health status of the battery and the number of cycles. It should be written normal and make sure the number of cycles is less than 300 or 500 depending on the MacBook model. Each model has a different number of cycles. For example, the maximum number of cycles 13 in MacBook Pro 2012 early inches is maximum, while the number of cycles 1000 late in MacBook Pro 15 inches is limited 2008. You can find more information on the cycle here: https: / /support.apple.com/en-us/HT201585

Check the charger

Checking the charger is also important. Make sure it can plug in and charge the Mac properly, otherwise you will have to spend extra money to buy the new one.

Disable firmware password

Turn on the Mac by pressing the power button. Once you hear the start chime, press and hold the Option key. If you are prompted to enter a password, it means that the owner has not yet disabled the firmware password. Tell him or her to turn it off.

Check the state of the hard disk

Open Finder> Applications> Utilities> Disk Utility and click on Apple SSD the first list you will find under Internal. Check the SMART (Self-Monitoring Analysis Technology) report in the right sidebar and make sure that the report is checked. Then, in the top menu bar, click First Aid to check the status of the hard drive.

Run the Apple hardware test

Apple Hardware Test (AHT) can help you resolve possible problems with the hardware component, such as logic board, memory, etc. This is useful, but it takes about a minute to a minute and 15 minutes. You can see the steps to run AHT here.

Test the functionality of all keys

Look for a place or text editing application where you can type something to test all the functions of the key. Type all the keys one by one, then try to use the shift key. Make sure that all the keys work well and that you feel comfortable when you type something. The trackpad test is also necessary. Check if it also works perfectly.

Check the dead pixel
