AppleSpacesSwitchOnActivate is represented by the second button on print below
In the code below, I get the current value and after I change. This can be tested in terminal with
defaults read -g AppleSpacesSwitchOnActivate
// getting value of AppleSpacesSwitchOnActivate
let switchOnActivate = CFPreferencesCopyAppValue("AppleSpacesSwitchOnActivate" as CFString, ".GlobalPreferences" as CFString)
print(switchOnActivate as! Bool)
// setting value of AppleSpacesSwitchOnActivate to false
CFPreferencesSetAppValue("AppleSpacesSwitchOnActivate" as CFString, false as CFBoolean, ".GlobalPreferences" as CFString)
CFPreferencesAppSynchronize(".GlobalPreferences" as CFString)
Basically, the value AppleSpacesSwitchOnActivate is changed, but the change is not effective until killall Dock.
Is there some way to update dock preferences plist without killall Dock?
