In 2026, Brazil finally surpassed the 60% mark for personal computer penetration in urban households — and much of this growth was driven by premium laptops that, paradoxically, became more accessible with the real’s strengthening against the dollar throughout 2025. In this scenario, the MacBook Air with M4 chip, launched by Apple in March 2025, entered as a protagonist: a machine that promised to redefine the concept of “high-performance ultraportable” without sacrificing the absurd battery autonomy that became the Air line’s trademark.

The central problem that the MacBook Air M4 tries to solve is classic but still relevant: how to deliver sufficient processing power for content creators, developers, and business professionals without needing a fan, without weighing more than 1.5 kg, and without dying at the outlet in the middle of a meeting? During ten years reviewing gadgets for publications like TechCrunch and The Verge, I saw dozens of laptops promise this and fail in at least one of the three criteria. The M4 is the first one that, honestly, didn’t fail in any.

Over six weeks of intensive use — including 4K video editing in Final Cut Pro, heavy code compilation sessions in Xcode, simultaneous video calls, and even gaming tests with emulation — I collected real data on performance, temperature, autonomy, and of course, calculated the financial impact of buying this notebook in Brazil in 2026. Here is the definitive review you needed before deciding.

Technical Specifications

Pros and Cons

Pros:

• Impressive raw performance: the M4 delivers up to 35% faster single-core CPU speed compared to M3, according to Geekbench 6 benchmarks (single-core ~3,800, multi-core ~15,200)
• Real autonomy of 14 to 15 hours in mixed use — one of the best results I’ve measured on any laptop
• Fanless design (no cooling fans) resulting in zero noise and comfortable chassis temperature even under moderate load
• 12MP webcam with Center Stage is, without exaggeration, the best integrated camera on the laptop market in 2026
• Liquid Retina display with excellent P3 color gamut coverage for color-critical work
• MagSafe return as a dedicated port frees both Thunderbolt 4 ports for simultaneous use
• Native support for two external monitors simultaneously (new feature compared to M3 Air)
• Unified memory shared between CPU and GPU eliminates bandwidth bottlenecks

Cons:

• No cooling fan means thermal throttling (performance reduction) under sustained loads beyond 15-20 minutes — long compilations or heavy renders suffer from this
• 256GB base SSD at R$ 12,499 is criminal in 2026 — minimum recommended is 512GB (R$ 14,499)
• Only 2 USB-C ports: for professionals with multiple peripherals, a hub is mandatory
• Display still lacks ProMotion (no adaptive refresh rates above 60Hz) — the MacBook Pro M4 wins here
• No complete Apple Intelligence support in Brazilian Portuguese yet (generative AI features limited to English)
• Price in Brazilian reais suffers from import duties that inflate the value by ~60% over US pricing

Cost-Benefit Analysis

Let’s be direct: R$ 12,499 for the base model is expensive. Period. But the equation changes when you look at the total cost of ownership over three to four years, which is the real usage cycle of a premium laptop in Brazil.

The M4 runs macOS Sequoia with optimizations that guarantee software support until at least 2031. Apple has a history of extended support — the M1 from 2020 still receives security updates in 2026. This means you’re buying not just a notebook for today, but a machine that will keep up with your workflow for years without needing an upgrade.

For content creators, the math checks out quickly: editing 4K ProRes video in Final Cut is an experience that Windows laptops in the same price range (R$ 10,000 to R$ 14,000) simply cannot replicate with the same fluidity. For iOS/macOS developers, there is no alternative — you need a Mac. For the corporate user who travels frequently, the combination of weight + battery + machined aluminum build quality justifies the investment.

Where the cost-benefit doesn’t add up: casual users who basically browse the internet, watch streaming, and work with Office documents. For this profile, a premium Chromebook or a Windows laptop in the R$ 5,000 to R$ 7,000 range solves 90% of needs with half the investment.

Comparison with Competitors

If you’re evaluating Windows ecosystem alternatives, it’s worth checking out our Samsung Galaxy Book 4 review in Brazil in 2026 — a machine that delivers an impressive AMOLED display for less money, but falls short in battery autonomy.

The major differentiator of the M4 compared to all listed competitors is the unified memory architecture. While an Intel or AMD processor in a Windows laptop needs to divide bandwidth between system RAM and integrated GPU VRAM, the M4 accesses a single pool of high-speed memory. In practice, this means that 16GB of RAM on a Mac does the work of ~24GB on a conventional Windows system for tasks like video editing and local machine learning.

Usage Tips and Configuration

At purchase time:

• Never buy the 256GB model if you’re going to use it for more than two years. The 256GB SSD in 2026 fills up in less than 12 months for most users. Go straight for 512GB.
• If budget is tight, prioritize RAM over storage: 24GB of RAM + 512GB SSD is a much more balanced configuration than 16GB + 1TB for those working with multiple tabs and heavy applications simultaneously.

Initial setup:

• Enable Low Power Mode in Battery Preferences for travel use — the performance loss is minimal (~8%) and autonomy increases by up to 2 hours.
• Configure Stage Manager (macOS window manager) if you use an external monitor: completely transforms productivity.
• Install Homebrew (package manager for Mac) immediately if you’re a developer — eliminates most Unix tool compatibility headaches.

Common troubleshooting:

• Throttling in long renders: normal and expected in a fanless design. Solution: use an elevated stand that improves passive cooling through the aluminum chassis by ~15%.
• Essential Windows apps: use CrossOver 25 (updated in 2025 with improved DirectX 12 support) or Parallels Desktop to run specific Windows software — works surprisingly well with the M4.
• Two-monitor connection: requires certified Thunderbolt 4 cable for the second display. Generic USB-C cables may not work for the second monitor simultaneously.

Future of Technology

The M4 is a second-generation 3nm process chip from TSMC, and Apple has already signaled that the M5 — expected in 2026 for MacBook Pro and 2027 for Air — should use a 2nm process. This means more energy efficiency and performance, but don’t expect a revolution: the jump from M3 to M4 was ~35% in CPU; M4 to M5 will likely be similar.

What will really change the game in the next two years is Apple Intelligence becoming fully functional in Brazilian Portuguese. With 16 Neural Engine cores capable of 38 TOPS, the M4 is more than prepared to run local language models when Apple releases full support — and that will transform the MacBook Air into an offline generative AI tool that no competitor can match in the performance-per-watt ratio.

If you’re torn between buying now or waiting for the M5 Air, my recommendation is: buy now if you need a laptop for immediate work. The M4 will last years and the M5 Air shouldn’t reach Brazil before mid-2027 — and when it does, it will cost even more at launch.

And speaking of purchase decisions involving imports, if you’re building out your complete work setup, it’s worth reading our analysis on importing the Steam Deck OLED in 2026 — an interesting exercise on when importing makes sense and when Brazilian taxation kills the deal.

Final Verdict

The MacBook Air M4 is, without qualification, the best ultraportable on the market in 2026 for those living in the Apple ecosystem or willing to switch. The combination of performance, autonomy, absolute silence, and build quality has no direct equivalent. The only real barrier is the price in Brazil — inflated by a tax structure that penalizes access to cutting-edge technology.

If the budget allows and your workflow involves content creation, software development, or simply the need for a reliable laptop that lasts the whole day without an outlet, the investment pays off. If you want a notebook for basic tasks, there are smarter options for your wallet.

Overall Rating: 9.2/10
