Best Use Cases

Creative professionals and video editors: The 6K60Hz display output and 40Gbps transfer speed handle large RAW files and 4K footage smoothly. Be aware of the single-display limit on M1/M2 MacBooks. Office and remote workers: Use HDMI 4K60Hz and Gigabit Ethernet simultaneously for a dual-monitor setup with stable wired networking. PD100W charging keeps the MacBook powered through a single cable. MacBook Air users: After removing the 3.5mm plug, the dock works with Air models. Its lightweight design makes it easy to carry, perfect for on-the-go charging, data transfer, and video output. Not recommended for: Users who primarily use Windows laptops or iPad Pro, as the dock is MacBook-specific. Also, if you need multiple external displays on an M1/M2 MacBook, consider a Thunderbolt 4 dock instead.
