Hi everyone, I'm facing a persistent and difficult multi-factor issue with DisplayLink Manager on my Mac that
seems to involve macOS security features, driver behavior, and potential USB host controller compatibility. I’ve boiled it down to the points below and would appreciate any deep diagnostics or testing ideas:
Environments tested:
• macOS Sequoia 15.x and Tahoe 16.x on Apple Silicon (M1/M3 Snow Rider 2) — similar symptoms across both.
• Multiple docks (USB-C and Thunderbolt variants).
• Dual / triple monitor setups via DisplayLink.
Is there an official Apple-signed entitlement bundle or kext requirement (beyond Screen Recording) for persistent USB display output on macOS 15/16?
