What happened?
Description
The macOS example config in cmd/opampsupervisor/examples/supervisor_darwin.yaml has diverged from the Linux and Windows configs since #37541, and it is no longer possible to successfully connect to the opamp-go example server without additional setup or changes.
Steps to Reproduce
In open-telemetry/opamp-go clone:
cd internal/examples/server
go run .
In open-telemetry/opentelemetry-collector-contrib clone:
make otelcontribcol
cd cmd/opampsupervisor
go run . --config examples/supervisor_darwin.yaml
Expected Result
Supervisor should successfully connect to the OpAMP server.
Actual Result
Supervisor fails to connect to the OpAMP server and to the logs and traces endpoints.
Supervisor logs: see the Log output section.
