How Do I Get More RAM?
Apple offers higher memory configurations for their entire slim line of laptops (MacBooks, Mac Book Airs, and MacBook Pros), but buyers must select the memory configuration before they pre-purchase.
Advanced users might think they can add the RAM themselves, but because Apple solders the RAM onto the motherboard of MacBook Air and other recent MacBooks and MacBook Pros, the only way to truly get more is to replace the motherboard. This is however not equitable. If you absolutely need more RAM, your best option is to
replace the computer.
