Why do some docks have display issues with macOS?

macOS handles external displays differently than Windows. Native Thunderbolt/DisplayPort output works reliably. USB-C alt-mode HDMI works for 1-2 displays. Third-party display output (DisplayLink, InstantView) requires driver software that adds CPU overhead and can have compatibility issues with macOS updates. For the most reliable multi-display setup on MacBook, use a Thunderbolt 4 dock from CalDigit, OWC, or Apple-recommended manufacturers.

Can I use a Windows Thunderbolt dock with my MacBook?

Most Thunderbolt 4 docks work with macOS because Thunderbolt is a universal standard. However, some Windows-focused docks have macOS-specific issues — display detection problems, sleep/wake bugs, or missing features. Docks from CalDigit, OWC, Anker, and Belkin are tested with macOS and recommended. Always check the manufacturer's compatibility list for macOS support before purchasing.
