Bottom line: The M4 MacBook Air is genuinely capable for most 4K editing workflows. YouTube creators, social media producers, and corporate video editors will find it more than adequate. Professional editors with demanding sustained workloads should look at the actively-cooled MacBook Pro.
Whether 256GB is enough for the MacBook Air M4 depends on your usage patterns. For cloud-centric users, it works fine. For media creators, it will feel cramped.
256GB works for:
256GB limits:
M4 SSD performance:
Good news: Apple fixed the M2's SSD issues. The M4's 256GB uses dual NAND chips, providing proper speeds:
The M2's single-chip design caused slowdowns that are now resolved.
Performance tip:
SSDs slow down when nearly full. Keep at least 20% free space to maintain optimal performance.
Upgrade math:
Apple charges $200 for 256GB → 512GB. That same $200 buys a quality 1-2TB external SSD usable across devices. The Thunderbolt 4 ports deliver near-internal speeds for external storage.
Storage cannot be upgraded later. Since Macs typically last 5-7 years, consider your long-term needs now.
Recommendation:
Budget-conscious users comfortable with cloud storage can make 256GB work. If you have any doubt about future needs, either upgrade to 512GB or budget for external storage from day one.
For video editors, photographers with local libraries, or developers: skip the base storage and start at 512GB minimum.
Apple Intelligence is Apple's personal AI system built into macOS on the MacBook Air M4. It provides writing assistance, creative tools, and an improved Siri while processing most tasks on-device for privacy.
Writing Tools (system-wide):
Available in any text field across macOS:
Faster than external AI tools since it works directly where you type.
Creative features:
Enhanced Siri:
Live Translation:
How processing works:
The M4's 16-core Neural Engine handles most Apple Intelligence tasks locally, processing 38 trillion operations per second. Your data stays on-device for standard operations.
When tasks exceed on-device capacity, Apple's Private Cloud Compute servers assist. These run on Apple Silicon with privacy protections. Apple states they cannot access user data and nothing is retained.
Why 16GB base RAM matters:
Apple configured the M4 MacBook Air with 16GB minimum specifically to support Apple Intelligence models running smoothly on-device.
Local AI beyond Apple:
The M4's power supports third-party AI applications too. Apps like LM Studio and Msty Studio can run large language models entirely on your MacBook. Apple demonstrated running a 22-billion parameter model alongside 4K rendering without performance issues.
The MacBook Air M4 handles casual gaming well, but serious gamers should look elsewhere. The fanless design creates inherent limitations for demanding titles.
Benchmark results:
| Game | Settings | FPS | |------|----------|-----| | Shadow of the Tomb Raider | 1080p, Highest | 36-37 | | Baldur's Gate 3 | Below 1080p, Medium | 30-40 | | Civilization VI | 1920x1200, Highest | 38 | | Resident Evil 4 | Lower settings | Playable |
The 10-core GPU delivers 20-25% better graphics performance than the M3. Apple's Game Mode helps by prioritizing game processes.

The bottom line:
The MacBook Air M4 is the most capable gaming Air ever made. For casual gaming to unwind after productivity work, it delivers enjoyable experiences. For dedicated gaming, a MacBook Pro with active cooling or a dedicated gaming laptop will serve you better.
Don't buy a Mac primarily for gaming. But if you already want a Mac and gaming is a secondary interest, the M4 Air handles it respectably.
The MacBook Air M4 supports two external monitors while keeping the laptop lid open. That's three screens total: two external displays plus the built-in Liquid Retina display.
This is a major upgrade. The M3 MacBook Air only supported dual monitors with the lid closed.
Supported configurations via Thunderbolt 4:
Evolution of MacBook Air display support:
| Model | External Displays | Lid Open? | |-------|------------------|-----------| | M1/M2 | 1 monitor | Yes | | M3 | 2 monitors | No (clamshell only) | | M4 | 2 monitors | Yes |
The M4 also improved resolution support. Both external monitors can run at 6K, whereas the M3 only allowed 6K on one monitor.
Technical notes:
Who benefits most:
If your workflow involves multiple applications, spreadsheets, coding environments, or creative work, the triple-screen capability makes the M4 a meaningful upgrade. This feature alone convinces many M3 owners to consider switching.
For desk setups where you want maximum screen real estate without closing your laptop, the M4 finally delivers what MacBook Air users have requested for years.
For most M3 MacBook Air owners, upgrading to the M4 MacBook Air isn't necessary. The improvements matter, but they're incremental rather than transformational.
Performance gains:
The standout upgrade: External display support
This is the headline change. The M3 only supported two external monitors with the lid closed. The M4 can drive two 6K displays while keeping the built-in screen active. Three screens total, laptop open.
If the clamshell-only limitation frustrated you on the M3, this alone might justify upgrading.
Other notable changes:
Upgrade if you:
Skip if you:
The real opportunity:
Coming from an M1, M2, or Intel Mac? The M4 delivers substantial improvements in performance, display flexibility, and camera quality at a lower price than the M3 launched. That's a compelling package.
Coming from an M3? Unless you need that dual-monitor fix, your current machine will serve you well for years.
The MacBook Air M4 delivers 14-15 hours of real-world battery life on a single charge. That's not marketing fluff—independent testing backs it up.
Laptop Mag's standardized battery test (web browsing with video at 150 nits) measured 15 hours and 30 minutes for the 13-inch model. The 15-inch version came in at 15 hours and 14 minutes under identical conditions.
What this means for your day:
For students and mobile professionals, you can confidently leave your charger at home. A full day of classes, library sessions, and coffee shop work? The M4 handles it with battery to spare.
Expected battery life by task:
The efficiency story:
The M4 chip is more efficient than its predecessor. It delivers approximately 16% better performance than the M3 while consuming about 13% less power. You get improved speed without sacrificing endurance.
15-inch vs 13-inch battery:
The larger model packs a 66.5Wh battery versus 52.6Wh in the 13-inch. Both deliver all-day battery life for typical users, with the 15-inch offering a slight edge for extended sessions.
Quick charging option:
Need a fast top-up? The optional 70W USB-C adapter charges to 50% in roughly 30 minutes.
Bottom line: The MacBook Air M4 is genuinely an all-day laptop for most users. Pack your charger for intensive work sessions, but leave it home for normal productivity days.
