A new MacBook Pro comes with either two or four external ports, depending on the model you pick. A new MacBook Air has a pair of ports. But those MacBook ports are only of one type: Thunderbolt, which is compatible with USB-C. A 24-inch iMac comes with two Thunderbolt/USB 4 ports; some models also include two USB-C ports. You probably have devices that use USB-A, Thunderbolt 1, Thunderbolt 2, DisplayPort, HDMI, or something else. How do you connect these devices? With an adapter.
If you’re planning to buy a new 24-inch iMac, MacBook Pro, or MacBook Air, make sure you set aside a considerable amount of cash for the adapters you need. Apple doesn’t include any in the box, except for a power adapter.
Satechi Slim Aluminum Type-C Multi-Port Adapter with Type-C Charging Port
Your best bet is to get a combination dock, like the Satechi Slim Aluminum Type-C Multi-Port Adapter ($60 on AmazonEdit non-product linkRemove non-product link). It connects via USB-C, and includes a USB-C pass-through port, two USB 3.0 ports, and an HDMI port with 4K (30Hz) support. With this, you don’t have to carry around multiple adapters.
If you don’t want a dock, or you can’t find a dock with the mix of connections you need, Apple or another company probably has an adapter for you. We’ve come up with this guide to help you sort out what you need, and we link to the appropriate adapter in the online Apple Store or on Amazon.
Be sure to check the return policies; sometimes adapters from third-parties don’t work. Read user reviews whenever possible, and read the specifications to make sure the adapter can do what you need it to do.

How to connect USB-C devices
The Thunderbolt ports in the current 24-inch iMac, MacBook Pro, and MacBook Air work with USB-C devices, which have the same connector shape. If you want to use a USB-C device, you can just plug it into one of the Thunderbolt ports. No adapter necessary. Whew.
USB-A is the USB connector with which you’re probably most familiar. It’s the USB connector that was on the previous MacBooks. (Terms like USB 4, USB 3 and USB 2 refer to the speed at which data travels through the connector.)
The name of the cable is confusing, because it could be mistaken for micro USB. But if you check the product page on StarTech’s website, you can see a clear shot of the micro B SuperSpeed connector on the cable, which is quite different from micro USB.
More recent iPhones and iPads include a USB-C to Lightning cable, and the iPad Pro includes a USB-C charging cable, so you don’t need the adapter for those devices.

Apple offers the USB-C Digital AV Multiport AdapterEdit non-product linkRemove non-product link, a $69 device that also provides a USB-A port and a USB-C port that’s for charging only. Be warned: Apple released a new version of this adapter (model number A2119) in August 2019 that supports HDMI 2.0. The older version (model number A1621) supports HDMI 1.4. When shopping, check the model number (at an Apple store, you likely will get the new model). Apple has a support document that details the differences between the two adapters.
To connect a VGA display, Apple has a USB-C VGA Multiport Adapter ($66 on AmazonEdit non-product linkRemove non-product link). In addition to a VGA to USB-C connection, it also provides a USB-A port for connecting a USB device, and a USB-C charging port to keep your laptop battery happy.
You’ll probably use Wi-Fi most of the time, but using an ethernet connection has its advantages. To connect to an ethernet network, you need an adapter like the Belkin USB-C to Gigabit Ethernet Adapter, which is available on AmazonEdit non-product linkRemove non-product link for $27.
How to connect SD cards

If you have a FireWire to USB-A cable, you can try using Apple’s $19 USB-C to USB Adapter. If you have a device with a FireWire 1394 4-pin connector—it was commonly used on video cameras and looks like this—and you need a way to connect, you can try using a USB-A to FireWire 1394 4-pin cable ($8 on Amazon) with the Apple’s USB-C to USB Adapter.
Many printers nowadays have wireless support, so there’s no need for a cable. But maybe you have an older printer, or you find wireless printing unreliable. Most consumer printers have a USB-B port. It’s a squarish connector, much different from USB-A or USB-C.
How to add a classic MagSafe power connector to the MacBook Air or MacBook Pro
The power adapter that comes with the new MacBook Pro and MacBook Air doesn’t have a breakaway MagSafe connector. MagSafe was a laptop lifesaver in instances where someone tripped over the power cable.
But you can still add a MagSafe connector. Tesha’s USB C Magnetic Charger Charging Cable ($20 on AmazonEdit non-product linkRemove non-product link) is a power-only cable that has an adapter that acts like a MagSafe connector. It is available in silver or black.
