The MacBook universe has grown so much If you're not up-to-date, it's easy to get lost among acronyms, generations, and screen sizes. From the first polycarbonate laptops with Intel Core Duo processors to the current MacBooks with M3, M4 or M5 chipsApple has been constantly refining design, power, and battery life.
In this guide, I'm going to tell you, calmly but directly, what each MacBook family offers.: what each MacBook family offersMacBook (the standard MacBook), MacBook Air, and MacBook Pro: what chips they use (Intel and Apple Silicon), what screens they have, how to identify them by model, and what their strengths and weaknesses are. The goal is for you to truly understand the features and specifications of all the models and to be clear about which one best suits your work or study style.
MacBook family history: from Intel to Apple Silicon
The MacBook saga officially begins in 2006When Apple decided to retire the 12-inch iBooks and PowerBooks in favor of Intel processors, that first white (and later black) polycarbonate MacBook quickly became the company's best-selling laptop, especially in the home and education markets.
The original polycarbonate design had a 13,3-inch screen with a 1280 x 800 resolution, integrated Intel GMA 950 graphics and, later, GMA X3100. These were computers designed for office tasks, browsing and multimedia, not for heavy graphics work or demanding games, something that was heavily criticized at the time due to the limited integrated graphics power.
In October 2008, Apple introduced the aluminum unibody concept. In the laptop range, it first appeared in a 13-inch MacBook, which, a few months later, would be rebranded as the MacBook Pro. The polycarbonate MacBook, however, endured several more revisions, including a white unibody version released in late 2009 with improved build quality, an NVIDIA GeForce 9400M, and an LED display.
With the arrival of macOS X Lion, Apple decided to stop manufacturing the iconic white MacBook.The entry-level laptop became the 11-inch MacBook Air, which became the most affordable model in the lineup. Years later, in 2015, Apple revived the "MacBook" name for an ultra-thin 12-inch ultrabook with Intel Core M processors, a fanless design, and a single USB-C port, conceived almost like an iPad with a keyboard.
That 12-inch MacBook will remain available until 2019.With a 2304 x 1440 pixel Retina display, butterfly keyboard, Force Touch trackpad, and USB-C charging, it's extremely light and quiet, but sacrifices some power compared to the MacBook Pro. Since its discontinuation, the current lineup is clear: MacBook Air as the entry-level, lightweight option, and MacBook Pro as the professional range.
Classic MacBook (2006-2010): Polycarbonate and the transition to Intel
The first MacBooks of 2006 completely replaced the iBook G4They offer bright 13,3-inch screens with a resolution of 1280 x 800, with a white (and, for a time, also black) polycarbonate casing, and adopt for the first time the MagSafe connector for power, as well as replacing the mini-VGA port with mini-DVI.
In terms of graphics, these models rely on integrated Intel GMA 950 chips. with up to 64 MB of shared DDR2 memory (up to 224 MB under Windows with Boot Camp). Later, the models from late 2007 and early 2008 made the jump to the Intel GMA X3100 with up to 144 MB of shared memory, still intended for light tasks, although quite optimized for video playback.
As for storage, configurations start at 60 GB and go up to 250 GBUsing 5.400 rpm Serial ATA hard drives, with options up to 500 GB and some 200 GB alternatives at 4.200 rpm. RAM ranges from a maximum of 2 GB DDR2 667 MHz in the first models to 4 GB in later generations, with two accessible SO-DIMM slots.
Wireless connectivity is covered with AirPort Extreme. (802.11a/b/g, and in newer models, also 802.11n), Bluetooth 2.1, and Gigabit Ethernet. The optical drive has evolved from combo drives (CD-RW/DVD) to a SuperDrive with support for DVD±R DL, with varying write and read speeds depending on the year.
The late 2009 redesign introduced a white polycarbonate unibody caseIt features an LED display, a glass multi-touch trackpad with an integrated button, an NVIDIA GeForce 9400M GPU with 256 MB of shared memory, and upgraded ports: mini DisplayPort, MagSafe (side-to-side), Gigabit Ethernet, two USB 2.0 ports, a combined audio output/input jack, and a Kensington lock slot. The FireWire (IEEE 1394) port and the infrared receiver for the Apple Remote are no longer included.
This unibody model incorporates an internal battery that is not user-replaceable.It offers approximately 6 hours of battery life and up to 1.000 recharges before the battery level drops to 80%. Furthermore, it features a new magnetic closure system that replaces the mechanical latch of the iBook, reducing the risk of mechanical failures.
MacBook Air: lightness, battery life and screen evolution
The MacBook Air was born as Apple's ultralight laptopDesigned for total mobility and users who prioritize weight and battery life over maximum power. Over the years, it has evolved from 11- and 13-inch models with Intel processors to the current generations with M2, M3, and M4 chips in 13- and 15-inch sizes.
The first Intel 11″ and 13″ models use Core 2 Duo processorsintegrated graphics chips and non-Retina displays. The identifiers range from MacBookAir2,1 to MacBookAir7,2, with different revisions between 2009 and 2017. These computers use PCIe or SATA SSDs., Wi-Fi 802.11n/ac and Bluetooth, and are compatible with macOS versions ranging from High Sierra to Monterey or Big Sur depending on the model.
Starting in 2018 comes the big leap to a 13-inch Retina display in the MacBook Air (MacBookAir8,1 and MacBookAir8,2 identifiers). They retain Intel processors, but incorporate a high-resolution display, thinner bezels, Touch ID on the keyboard, and Thunderbolt 3 ports. They are sold in space gray, gold, and silver colors and, depending on the year, support macOS Sonoma or earlier versions.
The total turning point comes with the 2020 MacBook Air M1 (model 1 MacBook Air M2020It debuts the Apple M1 chip with an 8-core CPU (4 performance and 4 efficiency cores), a 7 or 8-core GPU, a 16-core Neural Engine, and a unified memory architecture that shares resources between the CPU, GPU, and Neural Engine, with a bandwidth of 100 GB/s.
This Air with M1 offers configurations of 8 and 16 GB of unified memorySSD storage from 256GB to 2TB, a 13,3-inch Retina display, Thunderbolt/USB 4 ports, Wi-Fi 6, and up to 15 hours of web browsing and 18 hours of video playback. It is, by far, one of the best price-to-performance ratios Apple has ever offered in laptops.
MacBook Air with M2, M3, and M4 chips: 13 and 15-inch
The next generation arrives with the MacBook Air M2First in 13 inches (2022) and then in 15 inches (2023). Both models retain the three classic colors (space gray, gold, and silver) and add more modern variants like star white and midnight in the latest revisions. Model identifiers include Mac14,2 for the 15-inch Air with M2.
The M2 chip offers an 8-core CPU (4 performance and 4 efficiency cores) and a GPU with up to 10 cores, featuring a 16-core Neural Engine and 100 GB/s of unified memory bandwidth. This translates into a performance leap compared to the M1, especially in graphics tasks and light photo and video editing.
In terms of memory, MacBook Airs with M2 memory can be configured with up to 24 GB with unified memory, with SSDs ranging from 256 GB to 2 TB. The screen size increases to 13,6 inches in the updated model, with a Retina panel, a small notch for the camera, and brightness that can reach 400-500 nits depending on the version.
The MacBook Air with the M3 chip arrives in 2024. Available in 13-inch and 15-inch sizes (identified as Mac15,12 and Mac15,13, among others). The silver, star white, space gray, and midnight colors remain, with compatibility for macOS Tahoe 26 as the latest operating system. The M3 improves efficiency and graphics performance, while maintaining the philosophy of a silent, fanless laptop.
The leap to 2025 introduces the MacBook Air with the M4 chipAlso available in 13-inch and 15-inch formats (Mac16,12 and Mac16,13 models). Again, the four main colors are available, along with compatibility for macOS Tahoe 26. These devices take another step forward in on-device AI performance, ultra-low power consumption, and support for more demanding tasks, all within the Air lineup. For those following rumors about future generations, the M4 chip It is one of the focal points of attention.
MacBook Pro: professional range in 13, 14, 15, 16 and 17 inch models
The MacBook Pro family is Apple's professional range of laptops.It is geared towards users who need sustained power for video editing, 3D, intensive programming, or demanding creative work. Over the years, it has been available in 13, 14, 15, 16, and even 17-inch formats, spanning several generations.
The first MacBook Pros with Intel used Core Duo and Core 2 Duo processors.Later, it moved on to the i5 and i7 series, and finally to more powerful chips like the Intel Core i9 and Xeon in some configurations. Standard and Retina displays are offered, with unibody aluminum enclosures and a clear distinction from the MacBook/MacBook Air in terms of power and connectivity options.
In the Intel era, we find models with up to 4, 6, 8, and 10 cores. in Core i5, i7, and i9 processors, with base frequencies between 1,4 and 3,8 GHz and Turbo Boost technologies that reach from 3,2 GHz up to 5 GHz in the high-end variants. Some desktop and workstation models integrate Intel Xeon W processors with up to 28 cores, designed for desktop Macs, but they serve as a benchmark for the performance ceiling in the Intel era.
Retina displays became widespread starting in 2012 In 13- and 15-inch sizes, with resolutions far exceeding the 1280 x 800 of classic MacBooks, and with glossy or matte options for some MacBook Pro models. Brightness is improved and viewing angles are wider, although the greater saturation of glossy screens has both fans and detractors. If you're interested in the actual performance of these screens on specific models, there are reviews focused on the performance of Retina models.
In 2016 Apple redesigned the MacBook Pro with a thinner bodyIt introduces the butterfly keyboard and, in many models, the Touch Bar above the keyboard, with 13 and 15-inch versions. This redesign It comes with Thunderbolt 3 (USB-C) ports and is progressively abandoning traditional connectors, forcing the use of adapters in many cases.
MacBook Pro with M1, M2, and M3: The Apple Silicon Era
The real paradigm shift arrives in 2020 with the 13-inch MacBook Pro with M1 chip (MacBookPro17,1 identifier). This model features an 8-core CPU (4 performance and 4 efficiency cores), an 8-core GPU, a 16-core Neural Engine, and high-speed unified memory, with a bandwidth of 200 GB/s in some configurations.
The MacBook Pro M1 offers 8 and 16 GB of unified memoryIt features a 256GB to 2TB SSD and a bright 13-inch Retina display. It's compatible with macOS Tahoe 26 and comes in silver and space gray. Despite being the entry-level model in the Pro lineup, the performance leap compared to Intel is enormous, especially in video and compilation tasks.
In 2021, the 14-inch and 16-inch MacBook Pro models with M1 Pro and M1 Max will arrive. (MacBookPro18,1, 18,2, 18,3, 18,4 identifiers). These chips introduce CPU configurations of up to 10 cores (8 performance and 2 efficiency) and GPUs of up to 32 cores, with unified memories of up to 64 GB and bandwidths of 200 to 400 GB/s, depending on the version.

Processors, memory and multimedia engine in detail
If we look at Apple Silicon processors, the structure is repeated with variationsCPUs that combine high-performance and high-efficiency cores, integrated GPUs with numerous cores, dedicated Neural Engine, and unified memory architectures with different bandwidths, from 100 GB/s in basic models to 819 GB/s in top-of-the-range chips.
In the mid-range we find chips with 8, 10 and 12 core CPUs (like some M2, M3, and M4), GPUs with between 10 and 20 cores, a 16-core Neural Engine, and bandwidths ranging from 120 to 273 GB/s. These configurations are sufficient for most professional users who mix office work, development, photo editing, and some 4K video.
The most powerful chips, like the M4 Max or the higher-end variants of the M3 MaxThey offer CPUs with up to 32 cores (in dual-chip solutions or special configurations) and GPUs with up to 80 cores, with a Neural Engine of up to 32 cores and bandwidths approaching 800 GB/s. They are designed for workflows that previously required very high-end desktop workstations.
The multimedia engine is another key elementVirtually all current Apple Silicon chips include hardware acceleration for H.264, HEVC, ProRes, and ProRes RAW, video encoding and decoding engines, ProRes decoding and encoding engines, and, in the most recent generations, support for AV1 decoding. Some Pro and Max chips feature two video encoding engines and two ProRes engines, and even four in the most extreme configurations.
In previous generation Intel models, acceleration focused on H.264 and HEVC, with more modest video encoding/decoding engines. Previous generation Intel models They also suffered limitations and compatibility problems with some versions of macOS, which accentuated Apple Silicon's advantage in video editing.
How to identify your MacBook model and its compatible operating system
To find out exactly which MacBook you haveThe easiest way is to go to the Apple menu () in the upper-left corner and select "About This Mac." There you'll see the model name, approximate year, the chip it uses, and the installed memory. If you need more detail, you can open the System Information app.
If your Mac won't start or you don't have it in front of youYou have several options. You can look for the serial number engraved on the bottom of the casing, near the regulatory markings, or locate it on the original packaging next to the barcode. Entering that number on Apple's Check Coverage page will tell you the specific model.
Another helpful clue is the Apple part number.A part number of the type MQD32xx/A or similar, where the final letters vary by country or region. Apple maintains public lists where, based on that part number, you can identify whether it is, for example, a MacBook Air (13″, M2), a MacBook Pro (14″, M3 Pro), or a MacBook Pro (16″, M4 Max).
Each model also has an internal identifier such as MacBookAir10,1 or Mac15,3This is used to determine compatibility with different versions of macOS. For example, many recent MacBook Air and MacBook Pro models support macOS Tahoe 26, while 2012 or 2013 models are limited to macOS Catalina or Big Sur, and 2010-2011 models to macOS High Sierra.
Warranty, AppleCare+ and consumer rights
All MacBooks come standard with a one-year limited Apple warranty and 90 days of free technical support. During that period, Apple will repair manufacturing defects and provide basic hardware and software support. After that, you can upgrade your coverage with AppleCare+.
AppleCare+ adds expert technical support and extended hardware coverageThis includes an unlimited number of incidents for accidental damage resulting from use, each subject to a service charge according to the applicable terms and conditions. It's a particularly attractive option if you're going to be moving your laptop around a lot or if you use it in potentially hazardous environments. In recent cases, Apple has even has traded MacBook Pro affected by battery problems, an example of how coverage operates in specific situations.
In Spain, the General Law for the Defense of Consumers and Users It stipulates that the seller must offer free repair or replacement of products that do not conform to the sales contract. Furthermore, if the process of filing a complaint with the seller proves impossible or excessively complex, the consumer may file a complaint directly with the manufacturer.
It's important to understand the difference between the seller's legal warranty and Apple's commercial warranty. (including AppleCare+) are different layers of protection. Combining both ensures comprehensive coverage against manufacturing defects and, where applicable, accidental damage, provided you meet the terms and conditions.
MacBook Air vs MacBook Pro: Which model to choose today?
If you're hesitating between a MacBook Air and a MacBook ProThe key lies in the type of use. The Air, with M1, M2, M3 or M4 chips, offers a spectacular balance between lightness, power and battery life, making it perfect for students, remote work, advanced office applications, lightweight design and some photo/video editing without reaching extreme professional levels.
In terms of color options, the MacBook Air usually has the advantage.Space Gray, Silver, Gold, Star White, Sky Blue, or Midnight Blue, depending on the generation. MacBook Pros are typically limited to Silver, Space Gray, and, in recent models, Space Black. If you like to customize the look, the Air gives you a bit more freedom.
The Air offers Retina displays and sizes of 13,3, 13,6, and 15 inches. with resolutions around 2560 x 1664 pixels and brightness of 400-500 nits. The 14- and 16-inch Pro models make the leap to Liquid Retina XDR, with greater sustained brightness (1.000 nits in full screen, 1.600 nits in HDR), superior contrast, and higher resolutions, ideal for colorists, demanding photographers, and video editors.
In terms of memory and storage, the Air with M1 starts at 8-16 GB The Air features unified RAM and SSDs ranging from 256 GB to 2 TB, while the Air, with M.2 and M.3 slots, goes up to 24 GB of memory. The Pro, however, is in a different league, with 16, 32, 64, and even 128 GB of unified memory in Pro and Max chips, and SSDs of 512 GB, 1 TB, 2 TB, 4 TB, and even 8 TB in some configurations.
In terms of battery life, the MacBook Air with M1 and M2 gets around 15 hours of web browsing. and 18 hours of video playback, values that remain very competitive in the M3 and M4. The 14-inch MacBook Pro offers approximately 11 hours of browsing and 17 hours of video, while the 16-inch model can reach up to 14 hours of browsing and 21 hours of video, depending on configuration and workload.
In terms of price, the MacBook Air is clearly more affordable. than the Pro models. For example, in markets like Peru, prices have ranged from around 5.800 soles for a 256GB Air M1 to much higher figures for 16-inch Pro models with Pro or Max chips. The choice depends on whether you're really going to use the extra power of the Pro.
In practice, a good way to decide is to ask yourself three questionsConsider the types of tasks you'll be performing (basic, medium, or very demanding), how much you value battery life and weight, and what your budget is. If your tasks involve browsing, office applications, some light editing, and a lot of portability, the Air is usually the logical choice. If you earn a living with video, 3D, heavy programming, or large datasets, the Pro is clearly the better option.
Looking at the entire journey from the polycarbonate MacBooks to the latest Pros with M4 or M5It's very clear how Apple has gone from laptops that are perfectly adequate for everyday use to machines capable of replacing desktop workstations. Understanding what each family and generation offers will allow you to choose the MacBook that best suits you, without overpaying or finding yourself lacking power after just a few months.
