MacBook Air (Retina, 2018)

Can the RAM in the MacBook Air (Retina, 2018) be upgraded?

No. The RAM is soldered to the logic board and cannot be upgraded after purchase. The system comes with 8GB or 16GB of LPDDR3 memory, and this configuration is fixed.

What is the maximum RAM supported?

The maximum RAM is whatever was configured at the time of purchase—either 8GB or 16GB. There is no upgrade path after the initial build.

Can the internal SSD be upgraded or replaced?

Yes, but with significant limitations. The SSD uses a proprietary Apple connector and is not a standard M.2 drive. While it is technically removable, finding compatible replacement drives is difficult, and third-party options are limited.

What storage interface does the SSD use?

The SSD uses a proprietary Apple PCIe-based NVMe interface. It is not compatible with standard M.2 SATA or NVMe drives without an adapter, and adapter support is inconsistent.

Is the battery replaceable?

Yes, the battery is replaceable, but it is glued into the chassis. Replacement requires careful removal and is best performed by a professional or with proper tools and adhesive.

What other components are upgradeable?

The only user-serviceable components are the battery and the SSD (with caveats). The processor, graphics, and all other internal components are soldered and cannot be upgraded.

Can the Wi-Fi or Bluetooth module be upgraded?

No. The Wi-Fi and Bluetooth module is integrated into the logic board and cannot be replaced or upgraded separately.
