Are you looking to replace parts in your MacBook Air? You're in luck! There are a number of options available to you, depending on the part you need to replace. When it comes to screens, batteries, and logic boards, you can easily find replacements for your device. However, it's important to note that you won't be able to upgrade your laptop with these parts. You'll need to purchase the exact same motherboard that originally came with your device.
If you're looking for more information on what upgrades are possible for your Mac, the My Updates page on OWC is a great resource. Here, you can select your Mac and specify the model, and then explore what upgrades are available. This page not only shows you the internal updates, but also the peripherals such as eGPU docks and adapters that you can add to expand your old Mac. When it comes to battery life, it's normal for MacBook Air users to get 12 hours on a single charge.
Even if your laptop is a few years old, MacBook Pro users should still get several hours of battery life.
