5 Things to Know About the 2018 Retina MacBook Air’s RAM

Regarding the MacBook Air: 1. The RAM is soldered to the logic board and cannot be upgraded after purchase. 2. You must choose between 8 GB or 16 GB at checkout, as there is no later upgrade path. 3. Apple locked the configuration at purchase, so what you buy is what you get forever. 4. This constraint mirrors the same limitation found in Apple Silicon Macs, but on an Intel-era machine. 5. If you need more than 8 GB, buy 16 GB upfront, or you will be stuck with less memory permanently.
