About this Mac

Released alongside the M1 Macbook Pro, this is the most powerful Macbook Air model that features the new energy-efficient Apple M1 processor. The new Apple processor was designed and built in-house and is only featured on the Macbook Air and Macbook Pro line-ups.

The M1 processor has a clock speed of 3.2 GHz and is substantially more energy efficient than its MacBook Air Intel counterparts, allowing for up to 18 hours of use with the same battery capacity as previous models. Due to the new processor, this device does not support Windows emulation.

It does however feature an integrated 8-Core GPU which shares 8 GB of memory with the system through a Unified integration. The rest of the Macbook Air specifications match previous models with a 256 GB entry-level storage option and only 2 USB 3.1 ports.

The operating system of the MacBook Air can be upgraded from its pre-installed MacOS Big Sur 11.0.1 up to the current macOS. The dimensions of this device are .16-0.63 in x 11.97 in x 8.36 in and an average weight of 2.8 lbs (1.29 kg).

Common questions

Is MGN73LL/A the same as A2338?

Not exactly. MGN73LL/A usually points to a specific retail configuration, while A2338 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What MacBook Air is model A2338?

A2338 is the Apple A-number shown for this MacBook Air family. Use the order number, EMC, and model identifier on this page to narrow the exact configuration.

What does EMC 3578 mean?

The EMC number is another Apple hardware identifier. It helps separate closely related models that may share a similar name, year, or A-number.

Can the RAM or SSD be upgraded?

Check the spec table for the exact configuration. Many newer Apple Silicon Macs have memory and storage integrated into the board, so RAM and SSD upgrades are often not practical after purchase.

What macOS versions work with this model?

Use the model identifier, release year, and processor family from the spec table when checking macOS compatibility. Compatibility can change as Apple releases new macOS versions.

Is this MacBook Air still worth buying used?

It can be, depending on price, battery health, memory, storage, and condition. Compare this exact order number and model identifier against similar Techable listings before buying.

How much is this MacBook Air worth?

Value depends on RAM, storage, battery health, cosmetic condition, accessories, and market demand. Use the SellMac path on this page for a quote or use the identifiers here when comparing resale prices.

What should I search if this page is not the exact configuration?

Search the order number first when available, then compare the A-number, EMC, model identifier, year, chip, RAM, and storage. The same A-number can cover more than one configuration.
