Running Continuum93 on macOS: Code Signing Disclaimer

macOS includes a security system called Gatekeeper, which prevents unauthorized or unverified applications from running. If you attempt to launch Continuum93 and receive a message such as:

zsh: killed ./Continuum93

…it may be because macOS is blocking the binary due to the lack of a valid code signature.

 Fix: Manually Sign the Application (Ad-Hoc Signing)

You can enable execution of the application by manually applying an ad-hoc code signature. This can be done by opening Terminal and running:

codesign --force --sign - ./Continuum93

What This Command Does:

codesign: This is Apple's tool for applying or checking digital signatures on macOS binaries.

--force: Overwrites any existing (or broken) signature.

--sign -: Applies an ad-hoc signature, which doesn’t require a developer certificate. It marks the binary as trusted only on your machine.

This does not modify the app’s functionality, send data, or make it publicly trusted — it simply marks the binary as “safe to run” on your local system.

Important Notes and Risks This does not grant system-level privileges or bypass any core protections like System Integrity Protection (SIP). You should only run this command on software you trust and understand. Never apply code signing to a binary from an untrusted or unknown source. The signature is not persistent across systems. If you copy the binary to another Mac, you'll need to repeat this step. This is required due to Apple’s security policies. Since Continuum93 is not distributed via the Mac App Store or signed with a registered Apple Developer ID, it is treated as untrusted by default. The ad-hoc signature only affects local execution and does not weaken your system’s overall security posture.
