回答“Logic board replacement MBP 13 late 2013 retina display with mid 2014”Apparently, the late 2013 13" and mid 2014 logic boards are interchangable. According to this page, https://beetstech.com/product/logic-board-a1502-2013-2014, compatibility is set to late 2013 and mid 2014 models. The board in my late 2013 died and I found an eBay auction for a mid 2014 with 8gb of memory (my old board had only 4gb). I won the auction for ~$180. The cheapest way to get a board is to find an auction for a used one on eBay. Unfortunately, board auctions are few and far between but, generally, a comptible one crops up every couple weeks. If you check the site for new auctions every day, you'll eventually find a board that will probably cost half as much. There is high demand for boards which has caused the prices to skyrocket. Auctions generally force them to sell at the price that we actually find reasonable.

Just be sure to use keyboards prior to late 2011 as the hinge structure changed with the Late 2011 models. The other factor is getting the backlight to work. In short, it is impossible without some serious modding. The backlight on the MacBook Pro keyboards are variable to adjustment through the backlight brightness keys on the keyboard and the ambient light sensor. There is a backlight driver on the logicboard specifically for the purpose of controlling how much power is routed to the backlight to adjust its brightness. The A1342 MacBooks lack the driver since they were never intended to run a backlight system. Despite the disparaging news in the previous paragraph, a backlight can be modded onto the A1342 MacBook. Such a project would require the following.... 1) Order an...
