MacBook Air M4 Review: Still Worth It in 2026 — or Wait for M5?

The MacBook Air M4 is a laptop I've been using as my daily driver for the better part of a year. It handles everything I need across a busy IT consulting practice — client calls, development environments, managing networks remotely, writing, and the occasional deadline-driven marathon session. It has never once let me down.

My recommendation has nothing to do with the hardware itself — the M4 Air is genuinely excellent — and everything to do with timing. We're a week out from the M5 announcement, and that changes the calculus for anyone who hasn't pulled the trigger yet.

With 20 years in IT and a Surface laptop I left behind for this machine, here's what I actually think.

Quick Verdict

The Right Time to Buy — and When to Wait

Let me address the most important question first, because the answer shapes everything else.

The M4 MacBook Air launched at $999 in March 2025. As of late February 2026, Amazon and B&H are discounting the 13-inch model to between $749 and $899 to clear inventory before the M5 generation arrives. That's a meaningful discount on hardware that was already competitively priced.

If you find the 13-inch M4 at or below $850, buy it without hesitation. You're getting 16GB of unified memory, genuine all-day battery life, and open-lid dual-display support — capabilities that were missing or limited on the M3. At that price, waiting for the M5 at a $200–$300 premium is hard to justify for most users.

If you're being quoted $999 MSRP, wait. The M5 announcement is expected within days, and launch pricing will almost certainly be comparable to what the M4 cost at launch.

What Changed with the M4

The M4 MacBook Air launched in March 2025 with several upgrades that addressed persistent complaints about the M3 generation.

16GB RAM is now the base configuration. The M3 shipped with 8GB as standard — which was increasingly inadequate for modern multitasking. Doubling that baseline is the single most practical improvement in this generation.

Dual external displays work with the lid open. The M3 could only drive two external monitors in clamshell mode. The M4 runs two external screens alongside the internal display simultaneously.

The starting price dropped by $100. The 13-inch model came in at $999 (down from $1,099 for the M3), with a new Sky Blue color and an upgraded 12MP Center Stage webcam replacing the previous 1080p unit.

M4 vs. M3: Is the Upgrade Worth It?

The $150–$200 premium for a new M4 over a renewed M3 is well justified if you need 16GB of RAM or plan to use dual monitors with the lid open. If neither matters to your workflow, a refurbished M3 remains a reasonable budget option.

M4 Chip Specifications and Performance

The base M4 MacBook Air features a 10-core CPU, 8-core GPU, 16-core Neural Engine, and 16GB of unified memory.

The chip is built on Apple's second-generation 3nm process, using four performance cores and six efficiency cores — a configuration that keeps the chip fast under load while extending battery life during lighter tasks.

How Fast Is It, Day to Day?

In CPU benchmarks like Cinebench R24, the M4 scores approximately 30% higher than the M3 — but benchmarks aren't where I notice it.

What I notice: spinning up a Docker environment while a Zoom call is running and VS Code is indexing a large repo no longer causes the system to stutter. On my old Surface, that combination would create enough fan noise and lag to be distracting. On the M4 Air, it's silent and responsive throughout. Switching between client profiles in terminal sessions, pulling up Proxmox dashboards, and drafting documentation simultaneously — none of that causes hesitation. It's a machine that keeps pace with how I actually work, rather than one I have to work around.

What About AI Tasks?

The M4's Neural Engine significantly outperforms the M3 in AI benchmarks. Configurations with 32GB of RAM can run large models locally — including 32B parameter models like DeepSeek-R1 via heavy quantization — though at that scale, token generation is noticeably slow. For lighter AI tasks and Apple Intelligence features, the standard 16GB configuration handles everything well.

Thermals and Sustained Performance

Does the M4 MacBook Air Support Dual Monitors?

Yes — and with the lid open, which the M3 couldn't do.

The M4 supports up to two external displays at up to 6K resolution and 60Hz simultaneously, while the laptop screen remains active. That gives you a three-screen workspace from a machine that weighs 2.7 pounds.

I ran this setup in my office for several months before adding a Mac Mini M4 as a dedicated desktop. The MacBook's built-in display handled Slack and email; two external monitors covered code and documentation. The setup handled sustained consulting work without any stability issues.

For the connection, the most straightforward approach is running USB-C cables from each Thunderbolt 4 port directly to your monitors. If you need more ports or want a single-cable desk connection, a Thunderbolt dock handles it cleanly.

Our guide to Dell business monitors covers pairing options. The Dell 27" 4K USB-C monitor (S2725QC) is a reliable single-cable option that delivers 4K video and 65W of charging in one connection.

Apple Intelligence Integration

The M4 runs Apple Intelligence locally using the Neural Engine — writing tools, Image Playground, and Genmoji all process on-device, which is a meaningful privacy distinction from cloud-dependent AI systems.

Siri now handles typed or spoken input interchangeably and understands context across requests. Apple has also added optional ChatGPT access within Siri and the Writing tools, which can be disabled if you prefer not to use it.

In practice, the Writing tools' ability to summarize documents and refine drafts is the most useful day-to-day feature.

Is 16GB enough to future-proof for macOS updates in 2026 and beyond? Based on what Apple has shipped so far, yes — Apple Intelligence features run on the Neural Engine, not general RAM, and Apple has consistently optimized macOS to run well on base configurations. The risk isn't running out of RAM for AI features; it's running out of headroom for your own apps when AI processes are running concurrently. For general professional use, 16GB handles that fine today. If you're already pushing memory limits with VM workloads or multiple creative apps, 24GB is the safer long-term call.

Design, Display, and Input

The MacBook Air M4 is 0.44 inches thick and weighs 2.7 pounds (13-inch). The form factor hasn't changed since the M2 — Apple has focused on internal improvements rather than a redesign.

The Liquid Retina display on the 13-inch runs at 2560×1664 at 224 pixels per inch, with 500 nits of brightness and P3 wide color. True Tone adjusts white balance based on ambient lighting automatically. The display is sharp and comfortable for extended use.

Where Windows competitors lead: both the Dell XPS 14 (2026) and Surface Laptop 7 offer OLED panels with higher refresh rates. If display quality is a priority over everything else, it's worth considering.

The keyboard and trackpad remain the best available on any laptop. The Magic Keyboard has comfortable key travel with Touch ID in the power button, and the Force Touch trackpad is large and precise.

On finish durability: The Midnight colorway (deep dark blue-black) looks sharp but is a fingerprint magnet — noticeably more so than the Silver or Starlight options. After nearly a year of daily carry in a backpack and across client sites, the chassis itself shows no marks or wear, but Midnight requires a quick wipe-down to keep looking clean. If you're particular about that, Silver or Starlight are the lower-maintenance choices. Sky Blue holds up similarly to Starlight.

Battery Life: Apple's Numbers vs. Reality

Apple rates the 13-inch MacBook Air M4 at up to 18 hours of video playback and 15 hours of wireless web browsing.

Those figures are measured under light-use conditions. In a typical business workload — Chrome with multiple tabs, Slack, Zoom calls, and VS Code running simultaneously — expect closer to 11–13 hours of active screen time. That's still enough to cover a full workday without a charger at most locations.

I've never needed to carry a charger for a standard office day. For all-day travel with back-to-back video calls, it gets closer to the edge — but I haven't had the machine die mid-meeting.

The 13-inch houses a 53.8Wh battery; the 15-inch uses a 66.5Wh unit, which extends endurance by roughly 20% under comparable conditions.

Connectivity and Ports

The MacBook Air M4 includes:

• Two Thunderbolt 4 ports (USB 4, DisplayPort, charging capable)
• One MagSafe 3 port for dedicated charging
• One 3.5mm headphone jack with high-impedance headphone support
• Wi-Fi 6E and Bluetooth 5.3

MagSafe as a dedicated charging port means both Thunderbolt ports stay free for peripherals even while plugged in. The incoming M5 is expected to include Wi-Fi 7, which offers higher throughput and better performance in congested environments. For most current use cases, Wi-Fi 6E is more than sufficient.

How the M4 Compares to Windows Ultraportables

Windows ultraportables have narrowed the gap in 2026. Intel's Core Ultra Series 3, Qualcomm's Snapdragon X Elite, and AMD's Ryzen AI 300 series all deliver competitive performance and, in some cases, matching battery life.

Where the M4 leads: Single-threaded performance, macOS software optimization, and the unified memory architecture, which eliminates the CPU-GPU bandwidth bottleneck that affects traditional designs.

Where Windows competitors lead: OLED displays with high refresh rates. The Dell XPS 14 (2026) and Surface Laptop 7 both offer superior display technology at comparable prices. The Samsung Galaxy Book5 Pro is worth a look if you're comparing ARM-based Windows options for battery and AI performance.

The honest take: for most professional tasks, both platforms are capable. The decision usually comes down to software ecosystem preference. For a broader comparison, see our best business laptops guide.

How Much Does the M4 MacBook Air Cost?

The 13-inch M4 MacBook Air has an MSRP of $999. As of late February 2026, street prices have fallen to $749–$899 as retailers clear stock ahead of the M5 launch.

Upgrade pricing from Apple:

• Memory: 24GB (+$200) or 32GB (+$400)
• Storage: 512GB (+$200), 1TB (+$400), or 2TB (+$800)

Memory and storage cannot be upgraded after purchase — it's worth getting the configuration right at checkout.

The 15-inch Option

If you want more screen space without connecting external monitors, the 15-inch model is worth the extra $200:
