A MacBook Pro connected by one cable to a Plugable TBT4-UD5 Thunderbolt 4 dock on a desk, running two external monitors.

TL;DR

  • For two 4K displays: TBT4-UDZ and TBT4-UD5 ran test monitors at 4K 60Hz with HDR. Charging behavior needs follow-up.
  • For a compact setup: USBC-8IN1E and USBC-6IN1 each worked at 4K 144Hz with HDR; both reported 79W pass-through charging power.
  • For three displays: UD-ULTC4K ran triple 4K 60Hz, with an HDR issue on one test monitor through its DP Alt Mode based video output.
  • Still investigating: Variable charging power, selected display modes, and a storage disconnect with TBT-UDH2. Higher refresh rates offered in display settings were not always confirmed at the monitor.

Apple’s redesigned 16-inch M5 Pro MacBook Pro introduces a touchscreen PROLED XDR display and ships with macOS 27. Apple’s announcement covers the new design. Our first compatibility checks found working display and accessory connections across a range of Plugable products, alongside the exceptions below.

What the new MacBook Pro supports

Apple lists three Thunderbolt 5 ports, HDMI, SDXC, MagSafe 3, and a headphone jack. M5 Pro supports up to three external displays alongside its built-in touchscreen, including through a single Thunderbolt port. A dock’s supported setup still depends on its outputs, cables, and display technology. Apple technical specifications.

How we tested

We tested the 16-inch M5 Pro model running macOS 27.2 on November 6, checking connection detection, applicable USB, Ethernet and audio functions, charging, displays, sleep/wake, restart, and power off/on. NVMe storage was checked with AmorphousDiskMark.

Our early initial testing revealed encouraging compatibility across many of our Thunderbolt and USB-C products, along with a few behaviors that we’re continuing to investigate. Below, we’ll break down what worked, what we’re digging into, and which Plugable solutions are worth pairing for the new MacBook Pro.

Plugable docks and adapters tested

TBT4-UDZCompatibleTwo test monitors worked at 4K 60Hz with HDR. Applicable USB, Ethernet, audio and restart checks passed.
TBT4-UD5CompatibleTwo test monitors worked at 4K 60Hz with HDR. Applicable USB, Ethernet, audio and restart checks passed.
TBT-6950PDCompatibleDisplayLink connected monitor inputs confirmed 60Hz despite higher options shown in macOS settings. Native DP Alt Mode based video (through an attached USBC-HDMI8K) needs further high-refresh verification.

USB-C docks and compact display adapters

USBC-10IN1ECompatibleA test monitor worked at 144Hz with HDR, but took longer to show video after restart or power off/on.
USBC-8IN1ECompatibleA test monitor worked at 4K 144Hz with HDR. Applicable USB, Ethernet, sleep/wake and restart checks passed.
USBC-6IN1CompatibleA test monitor worked at 4K 144Hz with HDR. Applicable USB, sleep/wake and restart checks passed.
UD-7400PDCompatibleDisplayLink video worked through onboard HDMI and USB-C with attached USBC-HDMI8K adapters. Native DP Alt Mode based output reached 4K 60Hz HDR. Higher DisplayLink refresh rates remain unverified.
UD-ULTC4KCompatibleTriple 4K 60Hz monitors worked. Enabling HDR on the native output caused a black screen on one test monitor; two other monitors worked. DisplayLink monitor input confirmed 60Hz.
USBC-HDMI8KCompatibleThe current firmware that was tested was limited to 4K 60Hz. High refresh rate is available via a firmware update detailed here: https://kb.plugable.com/question/3758754

Charging

ProductInitial resultCharging findings
PS-EPR-140C1InvestigatingCharging power was reported at 94W, then 118W, then 140W, before returning to 94W. Consistent operation at 140W has not been established.

DisplayLink-based outputs require DisplayLink Manager for macOS. Check each dock’s setup instructions when combining those outputs with native video from the Mac.

Charging your MacBook Pro

Apple recommends at least 94W for USB-C charging and specifies a 140W-or-higher USB Power Delivery source for fast charging. Apple charging specifications.

Reported PD charging power varied during reconnection. The new MacBook Pro appears to only negotiate the charging wattage it needs, not defaulting to the highest available wattage at all times. Devices that offer up to 140W charging frequently were observed at 118W, or dropping to 94W. Pass-through charging hubs expected to offer 85W were observed at 79W. We have not established battery behavior under load or consistent fast charging, so charging remains an open item for a one-cable setup.

What we are still investigating

  • Display modes: On TBT-6950PD and UD-ULTC4K, settings offered higher DisplayLink refresh rates while the monitor reported 60Hz. UD-7400PD also offered higher rates that need independent confirmation. We are not recommending those higher DisplayLink modes yet.
  • HDR and reconnect behavior: The UD-ULTC4K HDR black screen, USBC-10IN1E’s delayed display after restart, and USBC-HDMI8K firmware differences need follow-up.
  • USB storage: TBT-UDH2’s storage disconnect and unexpectedly low benchmark performance need investigation before we recommend that tested storage connection.

Hot-plug detection and sleep/wake were marked as passing across the listed products; the restart-related exception is noted above.

If your setup behaves differently, contact Plugable support with your Mac model, macOS version, dock, cables, and monitor connections. We will update this guide as follow-up testing resolves the open items.

Frequently Asked Questions
