The MacBook Air M4 offers 16GB, 24GB, or 32GB unified memory. Since RAM cannot be upgraded later, choose carefully.
Why unified memory matters:
Apple Silicon shares RAM between CPU and GPU, making it more efficient than traditional systems. 16GB on M4 performs like 20-24GB on conventional laptops.
RAM recommendations by use:
| Configuration | Best for |
|--------------|----------|
| 16GB | Web, documents, photo editing, Final Cut Pro, Apple Intelligence, students |
| 24GB | Premiere Pro, software development, large RAW files, heavy multitasking |
| 32GB | Professional video, virtual machines, local AI models, future-proofing |
Software consideration:
Final Cut Pro is remarkably efficient, using ~2.2GB even for complex 4K multicam work. The base 16GB handles most FCP projects.
Adobe Premiere Pro is more demanding. Premiere users should consider 24GB or higher.
Upgrade costs:
- 16GB → 24GB: $200
- 16GB → 32GB: $400
Key facts:
- Memory is soldered and cannot be upgraded post-purchase
- Macs typically last 5-7 years
- Applications grow more demanding over time
Recommendations:
16GB: Genuinely sufficient for most users. Apple chose this baseline specifically for Apple Intelligence and modern macOS.
24GB: Peace of mind for uncertain users or those with moderately demanding workflows.
32GB: For users who know their work is demanding and don't want RAM to ever be a limiting factor.
When in doubt: 24GB provides meaningful headroom without the full $400 jump to 32GB.
