You can see that it shows the Model Year and the warranty. In this case, the Macbook’s warranty will end on September 26, 2015, but telephone support has already expired. This doesn’t tell you how old exactly the MacBook is, because all the MacBooks are not sold the same year they belong to. However, it gives you an idea how old it could be if the Purchase Receipt is missing. It also tells you if it is Retina Model or not. All retina models MacBooks come without a CD ROM and features a display with higher resolution. Resolution can be checked from “About This Mac” as well, by selecting Display Tab.

MacBook Display resolution how to check

If you check “About this Mac’s Screen” Properly, you will get more than a serial key. It tells you How many gigabytes of RAM the MacBook has, the Processor and its Speed.

If you want to know whether the laptop is dual-core or Quad core and its L3 and L2 Cache memory, click on System Report. You will get the screen like below image. If it doesn’t click on Hardware.

How to check if MacBook is dual core and Quad core

If it is dual-core, total number of core should show 2. In the above image it is Quad-core, so it’s showing total number of cores as 4.

Tip : 13-inch MacBooks are always dual core whether it’s retina or non-retina model.

Check Display for Shade, Dead Pixels and Scratch

Turn on Mac, and change its wallpaper to Solid background. Right-click on Desktop, select Change Desktop Background, and now select Solid Colors. You must apply White and Black color one by one, and check display. If there is any shade, dead-pixel or scratch on the screen, White/black background will make it visible to you.

How to check if the MacBook has SSD drive or SATA Drive of storage?

It can also be checked from Under About this Mac option. Select Storage tab and you will have all the detail. In the image below you see the storage type as Flash Store. It means you have the faster flash storage, and it is available in Retina and Air models only. Instead of Flash Storage if you see Solid State Drive or SSD, that means the MacBook has faster SSD storage, and if you see SATA, then it’s general Storage that older Macs come with.

What else you need to check before you buy a used MacBook?

  • Check the the body and the display properly in case you find any damage.
  • Bring a USB Stick and Microphone with you to check if those Ports are working fine.
  • Also bring a CD/DVD to check if the DVD Drive works well (if it features, because Retina model doesn’t have one).
  • Check if there is any password set. Sometimes, MacBook doesn’t ask to enter Password at login, but it does while installing the software. So change/set a password before paying.
  • Boot/reboot the MacBook a couple of times to make sure it doesn’t give any error.
  • Check the trackpad if it works well.
  • Check all the keys of the keyboard to make sure those work.
  • Connect the power cable to check if MacBook’s battery charges.
  • Don’t forget to check the camera using Photo Booth or Facetime app.
  • Try to open a couple of apps to make sure it has no issue.
  • Check sound, you can play video to check sound as well as display quality. Bring a video in USB stick in case seller doesn’t have one in computer.
  • Check WiFi. If you can’t connect to a WiFi network, you should at least check if it is showing WiFi networks or not.
