What is taskgated?

taskgated is a security process that enforces code signing on macOS.

What is taskgated?

taskgated (along with taskgated-helper) enforces task-level code signing rules. When a process tries to debug another process, reach task ports, or inject code, taskgated checks whether the requesting process has the right code signature and permissions.

What does it enforce?

taskgated controls access to:

• Task ports (which let one process inspect or control another)
• Debugging privileges
• Code injection
• Certain ways processes talk to each other

For example, when you attach a debugger to a running process, taskgated checks that the debugger is properly signed and allowed to debug.

Why does it matter for developers?

Developers often run into taskgated when debugging. If an app's code signature is wrong or the developer tools are not set up, taskgated blocks the debugging attempt. Running:

DevToolsSecurity -enable

gives development tools the permissions they need.

Should you worry?

No. It is a normal macOS security process that stops unauthorised processes from inspecting or controlling other processes. This is an important defence against malware.
