We could also set the environment variable, then JAVA will search all the path in the variable, until finding this library. However, OS X EI Capitan and later includes security technology, which no longer supports the environment variable 'DYLDLIBRARYPATH'. The right and wrong way to set Python 3 as default on a Mac There are several ways to get started with Python 3 on macOS, but one way is better than the others. 01 Dec 2020 Matthew Broberg (Red Hat) Feed Moshe Zadka (Correspondent) Feed. A lot of Mac tutorials mention the Library folder, which is where your macOS applications store things like settings and caches. Some settings can only be changed by editing files in the Library. But the Library is hidden by default.

Scriptable System Preferences

Mac OS X Leopard introduces a number of newly scriptable system preference panes, including: Accounts, Appearance, CD & DVD, Desktop, Dock, Expose and Spaces, Network, and Security.

System Preferences Application

Mac Osx Set Library Path

It is not necessary to script the System Preferences application to get or set the parameters for scriptable system preferences. Scripting of the preferences is done directly by using the preferences suites included in the System Events application dictionary.

However, occasionally you may wish to launch the System Preferences application and switch to a specific pane or tab for user review or interaction. Here are sample scripts for controlling the System Preference application: Download epson error 0x9a repair utility mac.

A script for quiting the System Preference application:
-- QUIT SYSTEM PREFERENCCES APPLICATION
if application 'System Preferences' is running then
tell application 'System Preferences' to quit
end if

A script demonstrating how to open a specific system preference pane, how to get the names of the anchors of a pane, and how to switch to a specified anchor (tab):
-- OPEN SYSTEM PREFERENCES TO THE SPACES PANE
tell application 'System Preferences'
activate
set the current pane to pane id 'com.apple.preference.expose'
get the name of every anchor of pane id 'com.apple.preference.expose'
--> returns: {'Main', 'Spaces'}
reveal anchor 'Spaces' of pane id 'com.apple.preference.expose'
end tell

Accounts Preferences

The scripting support in the Accounts Preferences is read-only, meaning you cannot use scripting to generate new users. You can use scripting to set the image used as the current user's picture.

The accounts preferences are read-only except being able to change the picture of the current user:
tell application 'System Events'
-- ACCOUNTS (Read-Only except picture of current user)
get the properties of the current user
--> returns: {class:user, picture path:file 'Mac OS X:Library:User Pictures:Animals:Cat.tif', home directory:file 'Mac OS X:Users:sal:', name:'sal', full name:'Sal Soghoian'}
get the properties of every user
--> returns: {{class:user, picture path:file 'Mac OS X:Library:User Pictures:Flowers:Yellow Daisy.tif', home directory:file 'Mac OS X:Users:sal:', name:'sal', full name:'Sal Soghoian'}}
set the picture path of current user to alias 'Mac OS X:Library:User Pictures:Flowers:Yellow Daisy.tif'
end tell

A script demonstrating how to add login items for the current user account:
tell application 'System Events'
-- LOGIN ITEMS
get the properties of every login item
-- {{class:login item, path:'/Users/sal/Desktop/View Remote Screen.app', hidden:false, kind:'Application', name:'View Remote Screen'}}
-- Adding a login item for the current user
make new login item at end of login items with properties {path:'/Applications/Dictionary.app', hidden:false}
end tell

Appearance Preferences

You can now script the look and functionality of basic user-interface controls.

A script demonstrating how to get and set the appearance preferences.
tell application 'System Events'
tell appearance preferences
get properties
--> returns: {scroll arrow placement:together, font smoothing limit:4, recent applications limit:10, scroll bar action:jump to next page, double click minimizes:true, recent servers limit:10, appearance:blue, recent documents limit:10, highlight color:{46516, 54741, 65535}, class:appearance preferences object, smooth scrolling:false, font smoothing style:automatic}
set properties to {scroll arrow placement:together at top and bottom, font smoothing limit:4, recent applications limit:10, scroll bar action:jump to here, double click minimizes:true, recent servers limit:20, appearance:blue, recent documents limit:20, highlight color:{0, 0, 32000}, smooth scrolling:true, font smoothing style:light}
end tell
end tell

CD & DVD Preferences

Using scripts, you can determine the actions performed when various discs are mounted by the computer.

A script demonstrating how to get and set the properties of inserted disks:
tell application 'System Events'
tell CD and DVD preferences
get the properties of video DVD -- Also: blank CD, blank DVD, music CD, picture CD, video CD
-- > returns: {class:insertion preference, custom script:missing value, insertion action:open application, custom application:file 'Mac OS X:System:Library:CoreServices:Front Row.app:'}
-- OPEN APPLICATION
set properties of video DVD to {insertion action:open application, custom application:'/System/Lirabry/CoreServices/Front Row.app:'}
-- RUN A SCRIPT
set properties of picture CD to {insertion action:run a script, custom script:file 'Mac OS X:Users:sal:Library:Scripts:Import Photo CD.scpt'}
end tell
end tell

Desktop Preferences

By manipulating the scriptable Desktop Preferences, you can control how images are used as desktop backgrounds.

A script demonstrating how to get the properties of the current desktop:
tell application 'System Events'
-- GET DESKTOP PICTURE SETTINGS
tell current desktop
get properties
--> returns: {display name:'Color LCD', random order:false, pictures folder:file 'Mac OS X:Library:Desktop Pictures:', picture rotation:0, class:desktop, change interval:60.0, picture:file 'Mac OS X:Library:Desktop Pictures:Aqua Blue.jpg'}
end tell
end tell

A script demonstrating how to set the desktop to display a folder of images in random sequence:
tell application 'System Events'
-- RANDOM ROTATION OF A FOLDER OF IMAGES
tell current desktop
set picture rotation to 1 -- (0=off, 1=interval, 2=login, 3=sleep)
set random order to true
set pictures folder to file 'Mac OS X:Library:Desktop Pictures:Plants:'
set change interval to 5.0 -- seconds
end tell
end tell

A script demonstrating how to set teh desktop to display a specific picture:
tell application 'System Events'
-- SET DESKTOP TO SPECIFIC PICTURE
tell current desktop
set picture rotation to 0 -- (0=off, 1=interval, 2=login, 3=sleep)
set picture to file 'Mac OS X:Library:Desktop Pictures:Plants:Agave.jpg'
end tell
end tell

Although scripting support is not integrated into the Screen Saver preference, you can use scripting to start the current Screen Saver:

A script to launch the ScreenSaver
-- LAUNCH SCREENSAVER
try
tell application id 'com.apple.ScreenSaver.Engine' to launch
end try

Dock Preferences

You can use AppleScript to control the way the Dock appears in Mac OS X:

A script demonstrating how to get and set the properties of the Dock preferences.
tell application 'System Events'
tell dock preferences
get properties
--> returns: {minimize effect:genie, springing delay:1.0, dock size:0.428571432829, magnification:false, springing:false, location:bottom, class:dock preferences object, magnification size:1.0, animate:true, autohide:false}
