Gatekeeper is a built-in security feature of macOS—originally introduced in Mac OS X Lion (10.7.3)—that enforces code signing and verifies downloaded applications before allowing them to run. This worklet ensures that Gatekeeper is always enabled on a macOS system.



# helper function to check if a command exists

function command_exists {

type "$1" &> /dev/null


# only evaluate if the spctl command is available

if command_exists spctl; then

# check if gatekeeper is enabled

spctl --status | grep -q "assessments enabled"

# yay? or nay?

exit $?


# spctl command not available, move along

exit 0



# enable gatekeeper for all users

spctl --master-enable

# did we succeed?

exit $?

Type is a shell built in. It maybe return something other than an executable program. Why not use which instead and get the executable path from that?
