When you want to buy a new MacBook but there are budget constraints, refurbished products can be an optimal option. You will get the same tech support as well as the warranty as you would with a brand new MacBook. 

In this article, we will help you understand all the aspects that ensure that the Mac you buy stays operational for years. 

Get Ready for Purchase

Always run a basic diagnostics check on the device you are purchasing. Make sure to carry a USB drive with the latest operating system installed on it so that you can boot the device before purchase. Also, don’t forget to carry along a pair of headphones and an external USB device that you can connect to test the ports. 

1. Check for Internal/External Damages

Diagnose the device thoroughly from inside and outside to ensure it doesn’t contain any big damage such as scratches and scuffs. If you find any loose screws, take it as a warning sign that the device is not serviced or repaired by a certified technician. 

2. Identify the Age of Old Mac

The old owner of the MacBook will always claim that the device is in like-new condition. But don’t only go for word of mouth and check the device physically to ensure that it is in good condition. Navigate to the About This Mac section to check for age and other specs.
