Mac Osx App Envrionment Variables
PATH variables are useful for some namely CLI (command line interface) apps. PATH variables allow certain apps to be accessed globally. So you don’t have to remember the full path to the app to use it. It stops things like this: /sbin/ifconfig – with no PATH variable assigned. Jun 20, 2008 If you are new to Mac OS X, you may need to know how to edit your PATH. The good news is that this is an easy task on Mac OS X. The recommended way is by editing your.bashprofile file. This file is read and the commands in it executed by Bash every time you log in to the system. Sep 06, 2017 This video covers how you can create temporary ENVIRONMENTAL variables in the terminal as well as how you can use the.bashprofile file to create permanent ENV variables. Also covered is how to. Easily check which versions of mac OS, iOS, iPadOS, or watchOS are compatible with your Mac model or iDevice. Guide includes OS X 10.8.x to macOS 11.0.x.
macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.
All-new Interface
macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.
Jun 26, 2010 All of the above are true. Variables in /etc/paths.d (known as pathhelper) will apply to all users of the machine all the time. Variables in /.MacOSX/environment.plist will apply to a single user's entire session. Variables in the various shell init files follow.
Widgets
Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.
Safari Extensions
With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.
The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.
Machine Learning
With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.
Mac Catalyst
Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.
User privacy on the App Store.
Later this year, the Mac App Store will help users understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.
Universal App Quick Start Program
Get your apps ready for Apple Silicon Macs. Create next-generation Universal apps that take full advantage of the capabilities the new architecture has to offer. Get all the tools, resources, support, and even access to prototype hardware you’ll need. You can also watch a collection of videos from WWDC20 to help you get started.
When I let go, it still zooms back. When I trash it, it still zooms back. 
When I right click there is no option to remove it from the dock.”Without knowing the specifics,of course, I cant diagnose the problem perfectly.
Tools and resources
Use Xcode 12 beta and these resources to build apps for macOS Big Sur.
Terminal User Guide
The shell uses environment variables to store information, such as the name of the current user, the name of the host computer, and the default paths to any commands. Environment variables are inherited by all commands executed in the shell’s context, and some commands depend on environment variables.

You can create environment variables and use them to control the behavior of a command without modifying the command itself. For example, you can use an environment variable to have a command print debug information to the console.
Mac Set Up Environment Variable
To set the value of an environment variable, use the appropriate shell command to associate a variable name with a value. For example, to set the variable PATH to the value /bin:/sbin:/user/bin:/user/sbin:/system/Library/, you would enter the following command in a Terminal window:
% PATH=/bin:/sbin:/user/bin:/user/sbin:/system/Library/ export PATHTo view all environment variables, enter:
When you launch an app from a shell, the app inherits much of the shell’s environment, including exported environment variables. This form of inheritance can be a useful way to configure the app dynamically. For example, your app can check for the presence (or value) of an environment variable and change its behavior accordingly.
Different shells support different semantics for exporting environment variables. For information, see your preferred shell’s man page.
Environment Variables On Mac
Although child processes of a shell inherit the environment of that shell, shells are separate execution contexts that don’t share environment information with each other. Variables you set in one Terminal window aren’t set in other Terminal windows.
After you close a Terminal window, variables you set in that window are no longer available. If you want the value of a variable to persist across sessions and in all Terminal windows, you must set it in a shell startup script. For information about modifying your zsh shell startup script to keep variables and other settings across multiple sessions, see the “Invocation” section of the zsh man page.
