How are MacBooks getting refurbished?

Refurbished MacBooks are computers which are pre-owned. They might have had a faulty part—a faulty SSD, a screen issue, a battery problem, an unresponsive keyboard—and were sent back to the manufacturer. Or, they were a display item that is now getting prepped to go on the market.

But how do MacBooks get refurbished?

1. A MacBook gets sent back to Apple or to a refurbisher. 
2. It is subjected to a battery of tests on both hardware and software to detect any issue.
3. Should any faulty part be discovered, the refurbisher will either fix it or replace it. Typically, a loose wire on a MacBook motherboard can easily be reconnected but a cracked screen has to be fully replaced.
4. After going through these repairs, the refurbished MacBook is thoroughly cleaned.
5. Finally, the device goes through another set of tests one last time. 

Product testing is crucial to make sure the device is ready for sale. Only when a MacBook passes these tests—just like a new one would!—can the refurbisher stamp them as refurbished.
