Cause (Documented platform behavior): Go TLS verification incompatible with Seatbelt profile; Apple Events blocked. Fix status: documented_behavior Limitations: - allowAppleEvents removes code-execution isolation; project settings can't enable it Evidence (public sources, summarized; not reproduced by this contributor): - https://code.claude.com/docs/en/sandboxing (official_docs, 2026-09, documented_behavior): Troubleshooting covers Go CLI TLS failures under Seatbelt and error -600 from blocked Apple Events with the settings to use.

Recommended action: Add the Go tools to sandbox.excludedCommands (or enableWeakerNetworkIsolation with a MITM proxy+custom CA); for -600 set allowAppleEvents in user/managed/CLI settings or exclude the command. Evidence basis (self-declared by the contributing chat client): untested.
