How to programatically switch between touchbar layouts on MacOS? - macos

Problem
I like the default Mac touchbar layout for everyday use, but I prefer the F1-F12 keys at my fingertips when programming. I also don't like holding down the fn key. That's why I wrote two AppleScripts to switch the layouts (included below).
The scripts work, but they are buggy. This is because they rely on opening the System Preferences app and navigating through the menus. I made a couple "apps" with Automator
that simply run the scripts and then assigned them to keyboard shortcuts.
This is an ok solution, but I'd like to do something more elegant. Ideally, my script should run behind the scenes and instantly change the touchbar layout instead of opening System Preferences, selecting items from drop-down-lists, and then finally closing System Preferences.
I messed around with the shell for quite awhile with no success before resorting to using Automator. Any suggestions from those who are more savvy with sort of thing?
Code
This one makes the F1-F12 keys the default touchbar layout:
tell application "System Preferences"
set the current pane to pane id "com.apple.preference.keyboard"
delay 0.25
reveal anchor "keyboardTab" of pane "com.apple.preference.keyboard"
end tell
tell application "System Events"
tell process "System Preferences"
click pop up button 2 of tab group 1 of window "Keyboard"
end tell
end tell
tell application "System Events"
tell process "System Preferences"
click menu item "F1, F2, etc. Keys" of menu 1 of pop up button 2 of tab group 1 of window "Keyboard"
end tell
end tell
tell application "System Events"
tell process "System Preferences"
click pop up button 4 of tab group 1 of window "Keyboard"
end tell
end tell
tell application "System Events"
tell process "System Preferences"
click menu item "Show App Controls" of menu 1 of pop up button 4 of tab group 1 of window "Keyboard"
end tell
end tell
quit application "System Preferences"
And this one does the reverse (makes app controls the default touchbar layout):
tell application "System Preferences"
set the current pane to pane id "com.apple.preference.keyboard"
delay 0.25
reveal anchor "keyboardTab" of pane "com.apple.preference.keyboard"
end tell
tell application "System Events"
tell process "System Preferences"
click pop up button 2 of tab group 1 of window "Keyboard"
end tell
end tell
tell application "System Events"
tell process "System Preferences"
click menu item "App Controls" of menu 1 of pop up button 2 of tab group 1 of window "Keyboard"
end tell
end tell
tell application "System Events"
tell process "System Preferences"
click pop up button 4 of tab group 1 of window "Keyboard"
end tell
end tell
tell application "System Events"
tell process "System Preferences"
click menu item "Show F1, F2, etc. Keys" of menu 1 of pop up button 4 of tab group 1 of window "Keyboard"
end tell
end tell
quit application "System Preferences"

Answer 1

On macOS Catalina when toggling the target setting it changes the value of the PresentationModeGlobal key in ~/Library/Preferences/com.apple.touchbar.agent.plist from appWithControlStrip to functionKeys or vise versa for those two choices. However, toggling it programmatically using the defaults command while it changes it in the UI it does not change it on the Touch Bar without also restarting the ControlStrip process.
The following example shell script code is what I use with a single keyboard shortcut to toggle between between Show App Controls and F1, F2, etc. Keys as that is what they are set to respectively in System Preferences > Keyboard > Keyboard on my system.
Example shell script code:
#!/bin/zsh
pmg="$(defaults read com.apple.touchbar.agent 'PresentationModeGlobal')"
if [[ $pmg == "appWithControlStrip" ]]; then
defaults write com.apple.touchbar.agent 'PresentationModeGlobal' 'functionKeys'
killall "ControlStrip"
else
defaults write com.apple.touchbar.agent 'PresentationModeGlobal' 'appWithControlStrip'
killall 'ControlStrip'
fi
Notes:
Other versions of macOS may require additional settings to be changed and or additional processes to be restarted, e.g., pkill 'Touch Bar agent' if applicable.
In Terminal you can use the read verb of the defaults command to examine changes to com.apple.touchbar.agent.plist as you make them in the UI to see if the value for additional keys needs to be changed too.
Side Note
As to your AppleScript code, here is how I'd do it based on your code as a single script to toggle between the two choices.
You didn't say what version of macOS are you running and since I do not have a pop up button 4 I cannot test the example AppleScript code shown below, however, this should eliminate having two separate scripts and it just toggles between the two with a single keyboard shortcut.
Example AppleScript code:
tell application "System Preferences"
set the current pane to pane id "com.apple.preference.keyboard"
delay 0.25
reveal anchor "keyboardTab" of pane "com.apple.preference.keyboard"
end tell
tell application "System Events"
tell tab group 1 of window 1 of process "System Preferences"
if value of pop up button 2 is "Show App Controls" then
click pop up button 2
click menu item "F1, F2, etc. Keys" of menu 1 of pop up button 2
click pop up button 4
click menu item "Show App Controls" of menu 1 of pop up button 4
else
click pop up button 2
click menu item "Show App Controls" of menu 1 of pop up button 2
click pop up button 4
click menu item "F1, F2, etc. Keys" of menu 1 of pop up button 4
end if
end tell
end tell
quit application "System Preferences"
Note: The example AppleScript code is just that and sans any included error handling does not contain any additional error handling as may be appropriate. The onus is upon the user to add any error handling as may be appropriate, needed or wanted. Have a look at the try statement and error statement in the AppleScript Language Guide. See also, Working with Errors. Additionally, the use of the delay command may be necessary between events where appropriate, e.g. delay 0.5, with the value of the delay set appropriately.
