- Its signature assistive technology: Eye-tracking devices that turn the human gaze into a hands-free mouse. To use the technology, students with limited motor skills and verbal difficulties simply need to look at their screen, and a mix of infrared projectors, cameras and machine-learning algorithms will detect their point of focus.
Control accessibility options with your keyboard and Siri
Many assistive applications like Dragon Dictate need to be allowed to control the computer for them to work reliably. Before OSX Mavericks this was done from the Accessibilty control panel and ticking the “Allow Access for Assistive Devices” checkbox. In OSX Mavericks this process has now changed and if your application needs this to be enabled this is how you now enable this. Mac requirements: Mac OSX 10.4 or later and USB port. Size: 4'L x 2½'W x 1'H. Requires Capability Switch and 2 AA Batteries. X 6-1/2' x 6-1/2'. Switch adapted trackball has large colorful buttons for direct use and three input jacks for switch use. It functions as your regular mouse device AND switch interface. Control your Mac with assistive devices With Switch Control, you can use one or more adaptive accessories to enter text, interact with items on the screen, and control your Mac. Switch Control scans a panel or user interface until a switch is used to select an item or perform an action.
You can use these keyboard shortcuts to control accessibility options, or ask Siri to perform these functions. For example, ask Siri to ”Turn VoiceOver On.”

The user will get prompted to enter their credentials. No need to use the do shell script.
So, to be safe, it appears it would be better to: ..instead.Argh - submitted too soon..
Almost correct: The file should NOT contain the trailing newline. So, that means it should be: (with the extra '-n' switch passed to echo)
Sorry about that..
I figured out it would even be better to change that into:
sudo echo -n 'a' > /private/var/db/.AccessibilityAPIEnabled
sudo chmod 444 /private/var/db/.AccessibilityAPIEnabled
Not using the -n would leave an 'a' followed by a 'newline' inside the file instead of just the 'a'
How To Enable Access For Assistive Devices Mac
It is useful to point out that System Preferences should not be open during this procedure. I discovered this while debugging a script that used the aforementioned code while I had the Accessibility prefpane open.
In Snow leopard I find that this does not work. It creates the hidden file, places the 'a' within, and in system preferences the 'enable access for..' is checked, but my applescripts still say 'access for assistive devices is disabled'. Only once I manually check the checkbox do the scripts work. This leads me to believe that something else, other than the .AccessibilityAPIEnabled file is happening under Snow Leopard.
My whole goal is to have a window/app management script that launches and places all of my startup apps/windows for dual monitors. I despise the automated mouse movement that comes with 'access for assistive devices' but I need this to move and resize the windows so in a single applescript i want to:
1. turn the access on
2. move and place the windows
3. turn the access off
