I've got a late model (Early 2015) 13" MacBook Air with a cracked plastic clutch cover. I can find them online, but I cannot find any instruction ANYWHERE about how to actually remove it. When you search, you find directions for early model MacBook Airs, then all sorts of MacBook Pros. But nothing for the 2013+ MacBook Airs. I'm afraid it might be permanently glued in place (knowing apple) or something like that, and the parts on the web are unusable manufacturing parts?
