Compatibility Facilitates Connectivity When the latest Thunderbolt appeared on Macs and PCs, it used a USB-C connector to deliver data transfer, video output, and charging power through the same cable. The OWC Thunderbolt Dock’s Thunderbolt ports use that same USB-C connector to create a multi-connectivity solution for 100s of millions of existing and future Thunderbolt computers and devices. Even the ports are fully USB4 future compatible.

Up to dual 4K displays or a 5K/6K/8K display, high-performance storage (including NVMe solutions), A/V mixers, a phone or tablet, even desktop accessories like a keyboard or mouse are all fair game. All accessories with past, present or future USB or Thunderbolt interfaces... all connect to the OWC Thunderbolt Dock.

Connectivity Reimagined Daisy chains are sensitive things. Removing any device besides than the last one will break your chain and render devices unusable until the chain is re-established. The OWC Thunderbolt Dock lets you create three separate “tree branches,” so you can remove devices from one chain without affecting or disconnecting the other. You can even take things up a notch by adding three Thunderbolt bus-powered devices. Feature Spotlight: add three Thunderbolt bus-powered devices to your chain such as the OWC Envoy Pro EX, OWC Thunderbolt 10G Ethernet Adapter, and OWC Envoy Express

Unleash Multi Drive Performance In the past, to daisy chain external storage you had to place your drive as close as possible to the front of the chain for fast and reliable performance. That wasn’t possible with bus-powered drives. They had to be placed last in the Thunderbolt chain… and the chain was limited to just one bus-powered device! Now, you can connect multiple portable SSDs directly to the OWC Thunderbolt Dock.

**Get Wired ** Nothing can put your work schedule behind faster than slow, low-quality Wi-Fi. Make bad connection a thing of the past by plugging into a wired network via the OWC Thunderbolt Dock’s Gigabit Ethernet port. You can enjoy uninterrupted downloads, fast and reliable file transfers, secure network access, and increased productivity in a collaborative, IP-based workflow.

The OWC Thunderbolt Dock’s SD card reader lets you transfer your creative files quickly, easily, and conveniently. You can even use the reader like an external drive to store or backup files at will.

  • Actual display support varies upon computer specifications. Supported Intel-based Mac models and Thunderbolt 4 PCs support two displays over Thunderbolt. The following Apple M1 (Apple Silicon) Mac models support a single display over Thunderbolt:
  • MacBook Pro (13-inch, M1, 2020) - MacBookPro17,1
  • MacBook Air (M1, 2020) - MacBookAir10,1
  • Mac mini (M1, 2020) - Macmini9,1
  • 8K resolutions are part of the DisplayPort 1.4 specification, which is supported by the OWC Thunderbolt Dock. However 8K setups are only possible when both the host computer and display also offer full support for this specification. Some Mac models offer only partial support for DisplayPort 1.4, limiting the resolution to (for example) 5K or 6K at 60Hz. Please review Apple's display specifications for your specific Mac to determine the maximum supported resolution and color depth.
