I heard a ‘poof’ today while wiggling some cable near where my power supply was plugged in. Sure enough my MacBook Air PS kicked the bucket. It’s an early 2015 model 13 inch. Can anyone vouch for the replacement models? I am in South America and the originals are just too expensive. Also the ones available here are 60 watts, but on the Apple’s site they sell the 45 watts. Will the 60 watts work on the 13 inch?
