Compare MacBook Air and Pro ports by chip, including Thunderbolt 4 versus 5, HDMI, SDXC, MagSafe and native external-display support.
The chip matters: the base M5 MacBook Pro has Thunderbolt 4, while M5 Pro and M5 Max models have Thunderbolt 5. The M5 MacBook Air has two Thunderbolt 4 ports. Do not buy an accessory based only on the words “MacBook Pro.”
Correction, September 5, 2026: updated the instructions and removed unsupported guarantees, release assumptions and testing claims. This guide follows the linked documentation.
Ports by model
Apple’s MacBook Pro specifications list three Thunderbolt ports, HDMI, SDXC, MagSafe 3 and a headphone jack. The Thunderbolt generation changes with the chip. The M5 Air specifications list two Thunderbolt 4 ports, MagSafe 3 and a headphone jack, with no built-in HDMI or SDXC slot.
A USB-C shape does not establish speed
Check the computer, accessory and cable specifications together. Apple lists up to 40 Gb/s for Thunderbolt 4 and up to 120 Gb/s for the supported Thunderbolt 5 configuration. Those advertised link rates do not mean an external drive transfers files at that speed.
A charging cable can have very different data capabilities from a Thunderbolt cable. A dock may share bandwidth among storage, networking and displays. Confirm backward compatibility with its manufacturer rather than assuming every older or newer accessory works merely because it plugs in.
Display counts are separate from port counts
Apple lists native support for up to two external displays on M5, three on M5 Pro and four on M5 Max, with resolution and refresh-rate combinations specified for each. Those models also support their built-in display. The Air supports two external displays under its documented conditions.
A hub’s number of video sockets is not proof of that many independent native displays. Check the host limit and the dock’s Mac-specific display modes. Products that require DisplayLink or other software have separate installation and compatibility considerations.
Charging over MagSafe or USB-C
MagSafe leaves a Thunderbolt port available for accessories. USB-C can combine dock connectivity and charging, provided the dock supplies adequate power. Fast charging depends on the exact Mac, adapter and cable: use Apple’s fast-charge compatibility guide. It is incorrect to say the fastest charging always requires MagSafe on every recent MacBook.
Before choosing a hub
List the devices you actually need to connect, their bandwidth requirements, your monitor’s resolution and refresh rate, and your charging needs. Check driver and operating-system support for specialist hardware; a Thunderbolt port alone does not establish support for an external GPU.
Our dock guide covers accessory selection. If you only need one missing port, a suitable adapter may be enough; neither every Air owner nor every Pro owner automatically needs a dock.
