I wrote this macOS bash Worklet with the help of Otto AI to check the speed of an internet connection on macOS devices.

It’s my entry into the Just Script It challenge! 

Evaluation

# This Worklet runs a speed test on Mac OS devices using the networkQuality command. 
# This command was included starting with Mac OS Monterrey.
#Exit non-compliant to run remediation script
exit 1
