From FireWire in Macs to Type-C in iPhones - the Apple Connect

• Apple has introduced several ports in the past
• iPhone 15 saw us bidding adieu to the lightning port forever
• MagSafe was introduced with the MacBook in 2006

Last year, while unveiling the iPhone 15 series, Apple made an announcement that caught the entire world’s eye. The Cupertino-based tech giant had shifted to USB Type-C charging for its iPhones, bidding adieu to the lightning port permanently. This meant good news for Apple users across the globe as they would now no longer have to carry a separate charger for their MacBooks and iPhones. The company also launched the AirPods Pro with the USB Type C during the event.

Now, Apple’s approach to ports and connectors has evolved significantly over the years, reflecting broader technological shifts, consumer demands, and the company’s relentless pursuit of simplicity and efficiency. As we gear up for the launch of the iPhone 16 in less than a month, let us take a look at how Apple has introduced various ports across its devices all these years.

Back to the beginning: Serial ports and ADB

In the early years of personal computing, connectivity was a complex affair, with various proprietary connectors and interfaces in use. Apple’s earliest computers, like the Apple II (released in 1977), used serial ports and parallel ports for connecting peripherals like printers and modems.


In 1986, Apple introduced the Apple Desktop Bus (ADB) with the Macintosh II and the Apple IIGS. ADB was a proprietary interface that allowed users to connect keyboards, mice, and other low-speed input devices. ADB remained a standard in Macintosh computers until it was eventually phased out in favour of USB in the late 1990s.

The floppy disk drive and SCSI era

Apple’s early computers also prominently featured floppy disk drives. The original Macintosh 128K (1984) famously included a 3.5-inch floppy disk drive, which became an industry standard.

To connect external storage devices and other peripherals, Apple also adopted the Small Computer System Interface (SCSI) in 1986 with the Macintosh Plus. SCSI allowed for the connection of hard drives, scanners, and other high-speed devices, offering a significant leap in performance over older interfaces.

The speed revolution with FireWire

The late 1990s saw the introduction of FireWire, a technology that Apple helped to develop. First introduced on the Power Macintosh G3 in 1999, FireWire was designed for high-speed data transfer, making it ideal for video editing, external storage, and other demanding applications. It became a popular standard in the creative industries, particularly for digital video cameras.

FireWire was available in two versions: FireWire 400 and FireWire 800, the latter of which doubled the data transfer rate.

The introduction of USB

One of the most significant shifts in Apple’s approach to ports came with the adoption of USB (Universal Serial Bus). Apple was one of the first major companies to embrace USB, beginning with the iMac G3 in 1998.


The iMac turned out to be a colourful, all-in-one machine that looked like it belonged in a futuristic candy store. But it wasn’t just the design that caught everyone’s eye; it was Apple’s decision to ditch its long-used Apple Desktop Bus (ADB) connector in favour of USB, the Universal Serial Bus. This was a big deal.

The colourful, translucent iMac famously omitted the floppy disk drive and instead offered USB ports as the primary means of connecting peripherals.

USB was a game-changer, offering a universal and user-friendly interface for connecting everything from keyboards and mice to printers and external storage. The widespread adoption of USB across the tech industry led to a vast ecosystem of compatible devices, further solidifying Apple’s commitment to this standard.

The MAGnetic connection

MagSafe, introduced with the MacBook in 2006, was a game-changer in laptop charging. The magnetic connector snapped into place, making it easy to connect and disconnect your charger without worrying about tripping over the cable and sending your laptop flying.

MagSafe went through a few iterations, including MagSafe 2, which was slimmer to fit Apple’s increasingly thin laptops. But in 2015, with the shift to USB-C, Apple discontinued MagSafe on its laptops, much to the disappointment of fans.

In 2021, MagSafe returned to the MacBook Pro, but this time, it’s known as MagSafe 3. While it’s a welcome return for many, it’s not backward compatible with older MagSafe chargers, meaning you’ll need a new one if you’ve been holding onto an older model.

Speed boost with Thunderbolt

In 2011, Apple introduced Thunderbolt, a high-speed interface developed in collaboration with Intel. Thunderbolt combined data, video, and power in a single connection, offering unprecedented versatility. The first Apple devices to feature Thunderbolt were the MacBook Pro and iMac released in early 2011.


Thunderbolt evolved over the years, with Thunderbolt 2 and Thunderbolt 3 offering even faster data transfer rates and greater versatility. Thunderbolt 3, introduced in 2016, merged with the USB-C standard, creating a single, compact port capable of handling a wide range of tasks, including charging, data transfer, and video output.

The 30-pin dock connector

As the company’s product lineup expanded to include mobile devices like the iPod, iPhone, and iPad, Apple developed new connectors tailored to the needs of these smaller, portable devices. The 30-pin dock connector, introduced with the 3rd-generation iPod in 2003, became the standard for connecting and charging iPods, iPhones, and iPads for nearly a decade.

This wide, flat connector was designed to do it all—charging, syncing, and connecting to a variety of accessories. It became the go-to interface for millions of iPods, iPhones, and iPads over the next decade.

But as convenient as the 30-pin connector was, it had its downsides. It was proprietary to Apple, meaning that if you had a non-Apple device, you were out of luck. And if you wanted to use the latest accessories, you often had to buy new cables or adapters.

The famous lightning port

Then, in 2012, Apple introduced the Lightning connector with the iPhone 5. Lightning was smaller, reversible, and more durable than the 30-pin connector, making it ideal for the increasingly slim and sleek designs of Apple’s mobile devices. Lightning also supported faster data transfer and charging speeds, helping Apple’s mobile devices keep pace with technological advancements.

Lightning quickly became the standard across Apple’s mobile lineup, including iPhones, iPads, and even accessories like the AirPods and Apple Pencil. Despite its proprietary nature, Lightning was embraced by users for its ease of use and reliability.

The lightning port served Apple devices for many years before being replaced by the USB Type C phones in iPhones last year.

Shifting to USB Type-C

After lightning port, Apple began to transition its devices from lightning and other proprietary connectors to USB-C. USB-C is a versatile and widely adopted standard that supports high-speed data transfer, video output, and power delivery in a compact, reversible form factor.

Apple first adopted USB-C with the 12-inch MacBook in 2015, a move that was initially met with some resistance due to the need for adapters and dongles. However, Apple’s commitment to USB-C has grown over time, with the port now standard on all MacBook models, as well as the iPad Pro, iPad Air, and iPad Mini.

As mentioned already, the most significant shift came with the introduction of the iPhone 15 series that marked the end of the Lightning connector and the complete transition to USB-C across Apple’s mobile devices. This change not only aligns the iPhone with Apple’s other devices but also with the broader tech industry, where USB-C has become the standard for everything from smartphones to laptops.
