Chosen Solution

My wife has an early 2015 MacBook Air.
I have a mid 2015 Retina MacBook Pro with dual GPU that has just given up the ghost. Can I use the pro’s SSD in the Air?
looking at ifixit’s instructions for replacing the SSD in both computers, they look physically different, but I think the connection and the dimensions are the same.
advice?

Give this a read The Ultimate Guide to Apple’s Proprietary SSDs Jump down the Generation 4 section for the details. Bottomline depending on which SSD you have it may not fit.
