This laptop is used, it has a small dent in the casing (see photos). It does not affect its operation. Portuguese keyboard.

MacBook Air is incredibly thin and light, yet more powerful than ever. It has a stunning Retina display, the new Magic Keyboard, Touch ID, up to twice the processor power, and faster graphics. And we’ve doubled the storage capacity. And with a 100% recycled aluminum construction, it’s the greenest Mac yet. Plus, its battery lasts from dawn to dusk. In short, the most popular Mac is also the perfect laptop for doing everything, all day long.

Characteristics:

• Retina display Four million pixels. Total immersion: The MacBook Air display has a 2560-by-1600 resolution — more than 4 million pixels — so get ready for out-of-this-world definition. Images are incredibly detailed and realistic. Text appears razor-sharp. And web pages and email look like printed pages because True Tone automatically adjusts the white point to the color temperature of the environment. You’ve got millions of colors, so everything looks great. Plus, the glass on the display goes all the way to the edge of the enclosure, so you can focus on what matters most.
• Performance A heavyweight that travels light. At just 2.75 pounds (1.29 kg), MacBook Air gives you the power to tackle all your daily tasks. The quad-core Intel Core i7 processor delivers up to twice the performance 1 and up to 80 percent faster graphics 4 so you can browse, play games or edit like a pro. Plus, up to 16GB of 3733MHz memory lets you work seamlessly with multiple apps. And you get ultrafast SSD storage starting at 256GB — twice the capacity of the previous standard configuration — and configurable up to 2TB — plenty of room for all your movies, songs, photos, files and games.
• Keyboard. Feel the magic. MacBook Air features the new Magic Keyboard, which debuted on the 16-inch MacBook Pro. It features an improved scissor mechanism with 1mm of travel for comfortable, precise typing with reduced typing noise. The inverted-T arrow keys make it easy to navigate lines of code, spreadsheets, or games. And ambient light-sensing backlighting lets you type even in semi-dark conditions.
• Force Touch trackpad: The Force Touch trackpad is one of the best in the world. It lets you interact with your Mac in different ways based on how hard you press. No matter where you click on the trackpad, you get ultra-precise control and consistent response. There’s plenty of room for Multi-Touch gestures like pinch and zoom, so your fingers can move freely.
• Touch ID Your fingerprint is your password. All the security and convenience of Touch ID is available on MacBook Air. Just place your finger on the Touch ID sensor and your Mac unlocks like magic. Forget about passwords and use your fingerprint to access documents, protected notes, and even system settings in no time. Shopping online couldn’t be easier or more secure: just choose Apple Pay at checkout, touch the Touch ID sensor, and you’re done. You don’t even have to fill out shipping or billing information. And don’t worry, because your card details are never shared with merchants. With Touch ID, your private data is safe.
• Apple T2 Security Chip. MacBook Air features the Apple T2 Security Chip, a second-generation silicon chip designed to put even more security on your Mac. So when you use Touch ID to unlock your Mac, open a protected document, or pay on the web, your personal information is safe and secure. With real-time data encryption, every bit of information stored on the SSD is automatically encrypted. And with the Apple T2 Security Chip, Siri is always there to open apps, find documents, play music, or answer questions — just by saying, “Hey Siri.”
• Speakers and camera The sound of a hurricane. With the latest in audio processing and calibration, MacBook Air sounds better than ever. Stereo speakers deliver twice the bass and are 25 percent louder.3 With wider stereo sound, listening to music or watching a movie becomes a beast. The FaceTime camera lets you make crystal-clear one-to-one or group video calls. And a triple-microphone array captures your voice more accurately when you make FaceTime calls, use Dictation, or ask Siri a question.
• Thunderbolt 3 Jack of all trades. Thunderbolt 3 combines incredible bandwidth with the versatility of the USB-C standard to create a universal port that reaches speeds of up to 40Gb/s. And if you don’t have one, MacBook Air includes two ports. This technology offers data transfer, charging, and video output in a single connector with twice the bandwidth of the previous generation. You can seamlessly connect your devices with a cable or adapter. Plus, the Thunderbolt 3 port is reversible, so no matter how you put it in, you’ll always get it right.
• macOS Catalina The Mac unleashes its power. With dedicated apps for music, TV, and podcasts. Smart features in the apps you use every day. And Sidecar, which turns your iPad into a second display for your Mac.
