Thank you for this guide! Using it, the comments, and the video, I successfully replaced the screen on my early 2015 MacBook Air (that I dropped almost a year ago) and have been using an external display for ever since. I know nothing about computers, but made sure to read the instructions and comments carefully and took notes and photos along the way to make sure I put it back together correctly. Took me about an hour to take it apart and 20 minutes to reassemble (probably slower than average). I used a replacement screen I bought on eBay and a toolkit from Amazon that had the appropriate screwdrivers and a spudger (cost less than a hundred bones for everything - much cheaper than a new laptop!).
