Code-sign and notarize DisplayLink Manager for macOS so it passes Gatekeeper checks and can be reinstated in Homebrew.
The DisplayLink Manager app for macOS is currently failing Apple's Gatekeeper checks due to missing code signing and notarization. This prevents smooth installation and usage for macOS users, especially those installing via Homebrew, the widely used macOS package manager.
Because of this, the DisplayLink Manager cask was deprecated and removed from Homebrew’s repository:
- GitHub Discussion (Homebrew maintainers' decision): https://github.com/orgs/Homebrew/discussions/6337
- Related PR removing the cask: https://github.com/Homebrew/homebrew-cask/pull/222423
Please update DisplayLink Manager for macOS so it is:
- Code-signed with a valid Apple Developer ID.
- Notarized via Apple's notary service.
Once this is done, Homebrew maintainers have indicated the cask can be reinstated, restoring easy installation for many macOS users.
This change will directly improve the installation experience and security compliance for thousands of users worldwide.

That's a solid fix. I actually got curious and pasted "Gatekeeper" into https://allmorsecode.com/ just to see its rhythm in audio beeps and blinking light signal mode—instantly, no signup needed. Sometimes it helps to step back and watch a word become pure signal before diving back into macOS security work.

In Nigeria, convenience matters a lot to me, especially when it comes to accessing platforms on the go. Using https://aviator.name.ng/app , I can quickly return to the interface whenever I have time. This makes it easy to continue learning, reviewing strategies, and staying engaged without needing a complex setup.
