Which power adapter do you need for your MacBook?
With a new batch of MacBooks arriving, someone asked if they needed to get a new power cord or would their old one work. That led me to quite a search on the Apple site.
The short answer to their question is that if they are moving from the same model to the same model (MacBook to MacBook), it would work. But if they are moving from different models (MacBook to MacBookPro), they needed the power cord that came with the MacBookPro.
Even though the power adapters look alike, the MacBook adapters are different for each model—and there are many models. After wading through the details on the chart, it turns out MacBooks can use any 60 watt adapter, MacBookPros use 85 watt adapters, and MacBook Airs use 45 watt adapters.
Except for the label, the MacBook and MacBook Pro adapters look alike. The MacBook Air adapter is shaped differently.
