Technical Specifications

Product History

Apple announced the M4 generation of MacBook Air in March 2025. The generation introduced the M4 processor to the MacBook Air family and added Sky Blue as a finish alongside Silver, Starlight, and Midnight.

The 2025 generation followed the MacBook Air with M3 introduced in 2024. Apple retained the thin, fanless enclosure concept while updating processing hardware, the camera system, and external-display capabilities.

A notable change in the M4 generation is support for up to two external displays while the notebook’s built-in display remains active. Earlier Apple silicon MacBook Air generations had more restrictive native external-display support.

Buying Considerations

Configuration is an important consideration because the internal unified memory and SSD are not conventional user-upgradeable components. The 16GB memory and 256GB storage combination should therefore be evaluated according to expected application and file-storage requirements.

• Verify MC6T4LL/A when the Sky Blue 16GB and 256GB configuration is required for identification purposes.
• Consider future storage requirements because the internal SSD is not designed for user replacement.
• Consider future memory requirements because unified memory cannot be upgraded through removable RAM modules.
• Account for the two-port Thunderbolt configuration when several wired peripherals will be connected simultaneously.
• A dock or hub may be required for USB-A, Ethernet, HDMI, memory cards, or additional wired connections.
• The 13-inch design emphasizes portability rather than maximum built-in screen area.
• The fanless design operates without cooling-fan noise but is different from actively cooled systems intended for sustained heavy workloads.
• Confirm software compatibility when replacing a Windows computer or an older Intel-based Mac.
• Check accessory dimensions carefully because fitted cases and shells can differ between MacBook generations.

Customer Feedback Summary
