MacOS – Make the TouchBar show app controls for one specific app at all times

There are multiple apps which allow you to track application usage.

• Timing App Paid
• Usage Free
• Time Sink Paid

I am not affiliated with any of these products in any way.

You can do this with two built in tools:

• Gatekeeper to allow/disallow access to apps (I've written about it in this post)
• Launchd to handle the schedule

Gatekeeper

Using Gatekeeper, we can create "rules" that allow you to block/enable apps. Using your example, we can create a list of Apps that is only allowed to run on Fridays:

spctl --add --label "FridayApps" /Applications/SomeApp.app 

The benefit of this, is that you can add multiple apps with the same label and enable/disable them in one single command:

sudo spctl --disable --label "FridayApps"   <---- For Saturday thru Thursday
sudo spctl --enable --label "FridayApps"    <---- For Friday

Launchd

For this you will need a simple script to enable/disable the apps and you need to run this as a daemon (needs sudo privilege) so it has to reside in /Library/LaunchDaemons.

I used the naming convention com.user.FridayApps.plist and FridayApp.sh for the script.

Bash Script:

#!/bin/bash

DOW=$(date +%u)   # Sets the Day of Week; 5 = Friday
TOD=$(date +%T)   # Sets the time of Day
start="12:00:00"  # Sets start time   
end="23:59:00"    # Sets end time

if [ $DOW -eq 5 ]
then
    if [[ "$TOD" > "${start}"  &&  "$TOD" < "${end}" ]]
    then
      /usr/sbin/spctl --enable --label "FridayApps"
    fi
else
    /usr/sbin/spctl --disable --label "FridayApps"
fi

Launchd .plist

##Load the `.plist`

sudo launchctl load com.user.FridayApps.plist

How this works

What's happening here is two things:

• launchd is running a script twice. Once at the time to run it on and another time to turn it off
• a simple bash script to turn on/off the enabled app. It verfies the date and then runs the appropriate command
