If you check out Apple’s Cables and Adapters page, you’ll be greeted with a lot of funny cables featuring a lot of indecipherable acronyms. What’s DVI? And how are Thunderbolt and Lightning different from each other?
Here’s a full breakdown of what adapter accessories are available on Apple’s website at the time of writing.
A Guide to Cable Types and What They Mean
First, let’s dive into what the different cable types are and what they’re used for.
Mac Cable Types
MagSafe and MagSafe 2: MagSafe power adapters work by holding the power connection in place magnetically. The benefit to this is that if you trip over or yank a cable out, the computer doesn’t come with it.
Apple is phasing out MagSafe in favor of USB-C, which allows for charging from any port.
5K DisplayPort: Some high-powered third-party monitors use this display standard to connect. They also require an adapter of some kind to connect to your Mac.
Mini DisplayPort: An older Apple standard for connecting a display. Though it’s exactly the same shape as Thunderbolt 2, it cannot transfer data. You can tell the difference between the two by the symbol above the port.
Thunderbolt 2: A super-fast data transfer and display connection standard, Thunderbolt 2 is as fast as a PCI Express connection. This means that hard drives that connect via Thunderbolt 2 theoretically have the same transfer speeds as internal hard drives. As a result, having these ports greatly enhances the future upgradability of your Mac.
Thunderbolt 3: The latest standard on Macs, and an improvement on Thunderbolt 2, although the ports are not the same. You can use Thunderbolt 3 to transfer data, connect a display, and charge your device.
Though Thunderbolt 3 ports use USB-C cables, not all USB-C ports support the Thunderbolt 3 standard. For example, the 12-inch MacBook has a USB-C port, but it doesn’t work with Thunderbolt 3. Check out our breakdown of Thunderbolt and USB-C ports on your Mac for more info.
FireWire: Before Thunderbolt, FireWire was Apple’s fastest data transfer standard. Apple has phased it out on all current Macs, but still sells an adapter.
iPhone and iPad Cable Types
Lightning: The current wired standard for all iPhone models. However, if the new iPad Pro is any indication, Apple will soon move on to USB-C for all iOS devices in the future.
30-pin: This standard was phased out with the debut of the iPhone 5 in 2012. Despite this, an adapter is still available on Apple’s website if you’re still using an iPhone 4S or older.
Non-Apple Cable Types
USB-C: The newest USB standard. It’s a small, reversible cable that’s as close to an all-in-one standard as we’ve ever had with USB. Thus, it’s not surprising that most new Mac notebooks ship with only USB-C ports. Most of the adapters on Apple’s website are USB-C-to-something.
See our overview of USB cable types for more detail.
USB 3 and 2: While USB-C is a physical connector type, USB 2 and USB 3 are connection standards. As you’d expect, USB 3 is much faster. You can tell the difference between them by the color inside a connector. USB 3 is blue, whereas older USB 2 cables are not.
3.5 mm audio: Your standard headphone jack cable.
SD, miniSD, and microSD Cards: SD stands for Secure Digital. These disks are essentially tiny flash storage drives. The adapters available in the Apple Store will allow you to connect these drives to your Mac. Some of them require an additional adapter themselves, depending on what kind of SD card you have.
VGA, DVI, and HDMI: The three most common display standards.
VGA, which stands for Video Graphics Array, is the oldest display standard. It’s an analog video signal. DVI, or Digital Visual Interface, is newer and higher-resolution. A lot of computer monitors use it.
HDMI, or High-Definition Multimedia Interface, is the newest standard. You almost certainly have several HDMI ports on your TV, and your computer monitor probably supports HDMI as well. It’s also the only standard that can carry both video and sound, and therefore doesn’t require an additional audio cable.
Ethernet: If you connect to the internet via a wire, this is the cable you use. Mac notebooks have done away with the port for this, requiring you to use an adapter or connect via Wi-Fi.
What Ports Does Your Mac Have?
Take a look at the sides of your Mac notebook, or the back of your iMac. Then take note of what ports you have available. This will vary based on your model.
Apple’s support website has a very handy page that helps you identify the ports on your Mac. It has pictures of all the possible ports and what they look like.
Without further ado, here are the adapters on Apple’s website and how you can use them.
