Finally your dream has come true and now you can work on the Mac computer, although it is not exactly what you always wanted: this Mac – is pre-owned and purchased not in the Apple store, but from its previous owner. Now it is necessary to check it and prepare for work. In order to start the internal verification process, you need the installation disc or flash drive with the current OS X. You need to do that in case the internal disk device is formatted or the OS is missing. In addition, you will need to check the functioning of all slots, Bluetooth and headphones.

Visual check

The verification should start with inspection of computer external condition. It is necessary to carefully and thoroughly inspect the Mac computer and check for possible external damage: check the case, lid etc. During such an inspection it is necessary to take a look at the lid, it shouldn’t “slide" the presence of such a drawback means that this Mac might have been dropped. The lid should close silently and smoothly. Carefully inspect all the screws on the back side of the computer: if you notice traces of their undoing, perhaps, Mac was repaired.

Built-in equipment test

Apple Hardware test – it is a mandatory procedure of built-in test. To run this procedure just push the D button for a while during the computer starts. This test will help to identify possible problems with internal elements. In this way it is possible to obtain data on important components of the device: CPU settings, memory, disc data, etc. It is Important to remember that information ANT cannot be changed, while the system information can easily be spoofed. The operational test lasts no more than 3 minutes, but it is better to run a full test for 50 minutes making sure the computer won’t be turned off.

Keyboard Test

All Apple products have its distinctive style and beauty. Many people like bright backlight of Mac keyboard, so you also need to check its homogeneity and the ability to adjust the brightness of the keyboard. It is necessary to examine each key, make sure no key is "sticky" and all of them are easy to press. To check the keyboard open a new document and press every single key.span>

Wireless interfaces check

Wi-Fi and Bluetooth – are important components of modern devices. Therefore, we need to test all wireless interfaces, which can be checked very easily, you just need to connect to them. In the absence of connectivity through Wi-Fi, you can use the modem in your iPhone. To check your Bluetooth you may use the communicator.

Testing other components

Headphones, microphone, speakers and camera are checked using calls via FaceTime and Skype, the camera can be tested separately by activating the PhotoBooth app: just record a video and view it. Headphones and connectors are checked with the help of headphones and related flash drives. The battery is checked via System Profiler, just go to the section "Power options " and check data on the number of cycles. The developer installed a battery life up to 1000 cycles, but with 600 cycles the capacity will fall, so since 500 cycles, the total cost of used Macs usually falls. Buying a new battery – is not a cheap «thing» to do. You also need to check the charging adapter that should be “original” and should have undamaged cables.

Firmware password

Firmware password – means the possibility of additional protection of your Mac with a password. If necessary, the system may lock the access to boot options. Password setting will make system reinstall or loading not possible without entering the required password. On the screen you will see the “lock” icon with a slider to enter the password. If you notice such a password on the screen – it is better not to purchase it, as this password can’t be removed, reset, or treated.

To sum up

Of course, buying used devices is tricky and may have its difficulties and nuances, although people who frequently buy digital devices on the secondary market are not scared of that. After all, in the secondary market you can buy inexpensive and modern computers that are quite expensive at official retailers. So why not buying a good Mac at the normal price, if you are experienced enough or have a friend who deals with computers and other devices.
