In this video, I perform both a CPU and RAM upgrade on this Early-2015 11-inch MacBook Air, making it the best possible 11-inch MacBook Air that can exist. I upgraded the CPU to a 3.1 GHz Intel Core i7-5557U, and the RAM to 16GB of 1866 MHz memory. While the CPU upgrade ended up not really being all that worth it, as I expected, the 16GB RAM upgrade will make a huge improvement to the usability of the system.
