GoLand macOS Debugging Limit: Delve Signing Behavior Across Releases

Direct answer

No. Automatic Delve signing in GoLand is not reliable across current macOS releases. It succeeds only when a valid code-signing identity exists in the local keychain, the keychain is unlocked, and the user approves the macOS signing prompt. If any of those conditions fail, manual signing of the bundled Delve binary—or pointing GoLand at a separately signed Delve executable—is the expected path. Debugging is effectively unavailable only when neither option can produce a binary with the com.apple.cs.debugger entitlement, or when System Integrity Protection blocks the target process itself.

Likely explanation versus confirmed behavior

Likely explanation: GoLand attempts to re-sign the bundled Delve binary at debug startup using the signing identity found in macOS Keychain Access. Because the bundled Delve is replaced with IDE updates, a previously signed binary can become unsigned after a GoLand upgrade, requiring the signing flow to run again. This version-specific behavior is not confirmed as a fixed support boundary.

Confirmed behavior: Delve on macOS requires the com.apple.cs.debugger entitlement to attach to a process. The IDE exposes a debugger executable path setting, so an externally signed Delve can replace the bundled binary. SIP may block task_for_pid regardless of signing, especially for protected system processes.

Support boundary

Situation	Supported action	When debugging stops
Keychain has identity and user approves prompt	Automatic signing of bundled Delve	Rarely; re-signing may be needed after IDE update
Automatic signing fails	Manually sign bundled Delve with codesign	If no valid identity exists or signing is not permitted
Re-signing is not acceptable	Configure a separately signed Delve path in GoLand settings	If the external binary lacks the debugger entitlement
No signed Delve available and SIP blocks attachment	None	Debugger launch failure; not a build error

Steps for this case

1. Locate the bundled Delve binary path shown in GoLand's debugger settings, then check its entitlements:

codesign -dv --entitlements :- /path/to/delve

Replace /path/to/delve with the actual path. Look for com.apple.cs.debugger set to true.

1. If the entitlement is missing and you have a valid Apple Developer identity in your keychain, unlock the keychain and allow the GoLand signing prompt when starting a debug session.
2. If automatic signing fails, manually sign the binary. Create a property list containing the debugger entitlement, then sign:

codesign -s "Developer ID Application: Your Team Name" --entitlements delve-entitlements.plist /path/to/delve

Point GoLand to the signed binary in the Delve debugger path setting, then start a debug session.

If launch still fails, open Console.app and filter for task_for_pid or securityd during the attempt to distinguish an entitlement problem from a SIP block.

Version differences

Because Delve is bundled and updated with GoLand, the signing state is tied to the IDE release, not the macOS release alone. A GoLand update can replace a signed Delve with an unsigned build, so automatic signing may succeed on one IDE version and fail on the next even on the same macOS version. This version dependency is not well documented as a fixed boundary; treat each IDE upgrade as a potential re-signing event.

Missing diagnostic detail

Do you have a valid Apple Developer code-signing identity in your local keychain, and is that keychain unlocked? This determines whether automatic signing can ever succeed or whether you should proceed directly to manual signing or an external Delve path.
