As I noted in a previous post, software virtualization allows you to simulate a hardware environment and run multiple operating systems on one computer. In doing so, these virtual machines can take advantage of the hardware components on a computer such as RAM and storage in complete isolation to the primary operating system.

There's currently no easy way of porting the desktop environment from macOS onto Linux. The desktop environment on macOS is mostly closed source, so you basically have three types of options for running a macOS desktop environment on Linux:

For option 1 there's a piece of software known as Darling, that has taken the first small steps towards this goal. The project has recently received a bit of "public interest" on HackerNews and other places, but it is still a very long way of from being practically useful for running the macOS desktop environment on Linux.

Finally - if all you're looking for is basically a bit of macOS "influence" on your Linux desktop - you might want to look into the Linux distribution elementaryOS. It's not a macOS desktop environment, and does not use parts of Darwin or anything like that - but it takes much inspiration from the way the macOS desktop environment looks.

Note: Windows users must restart the console to set the environment variable. Learn more about setting environment variables by reading one of our guides: How to set environmet variables in Linux, How to set environment variables in MacOS, How to set environment variables in Windows.

The values of environment variables can control the behavior of an operating system, individual utilities such as Git, shell scripts, user applications such as the Google Chrome browser, or deployed applications such as a Python web app.

We delve deeper into the scope of environment variables in shells and shell scripts later in this article, as well as how to change the default scoping behavior by learning how to execute a script in the context of the current shell.

When running a command or script from the shell, the current shell is the parent process and the command or script is a child process, which only has access to the environment variables from the current shell or parent process.

Now you might be wondering what if you want to temporarily expose an environment variable to multiple commands? It may not work the way you would expect. Let's try running our script twice using && syntax:

Where and how you set environment variables depends on the operating system and whether you want to set them at a system or individual user level, as well as what shell you're using, e.g. bash or zsh (which is now the default in Mac).

If you're wondering how to tell if printenv SOME_VAR actually worked or whether SOME_VAR was just empty, you can inspect the $? variable after the printenv command and if the exit code was 0, the environment variable exists.

This is because Virtual Machines (VM) and Docker containers provide a sandboxed environment for applications to execute in, therefore any environment variable only affects that specific application in that VM or container.

Because applications are configured differently from development to production, configuring an app using environment variables means only the values need to change when deploying to different environments, not the source code.

Supplying application config and secrets using environment variables is precisely what the Doppler CLI does, and our mission is to make this as fast, easy, and secure as possible with integrations for every major every cloud provider and platform.

Whether you need a customizable operating system or a better environment for software development, you can get it by dual booting Linux on your Mac. Linux is incredibly versatile (it's used to run everything from smartphones to supercomputers), and you can install it on a MacBook, iMac, Mac mini, or any other kind of Mac.

What are the Environment variables, and why use them?Environment variables are system variables with a specific meaning that can be referenced when necessary all over the Operating System. They usually begin with a $ symbol in bash. It must also be noted that when storing API keys or secret data for Production, environment variables are not the best option. They are handy for testing and development as most languages have inbuilt support.

Conda is an open-source package and environment management system that runs on Windows, macOS, and Linux. Conda quickly installs, runs, and updates packages and their dependencies. It also easily creates, saves, loads, and switches between environments on your local computer. It was created for Python programs, but it can package and distribute software for any language.

I recently made a django project using virtualenv on my mac. That mac broke, but I saved the files and now I want to work on my project using my linux computer. I am now having some difficulty running the virtual environment in Ubuntu.

The architecture of macOS incorporates a layered design:[61]the layered frameworks aid rapid development of applications by providing existing code for common tasks.[62] Apple provides its own software development tools, most prominently an integrated development environment called Xcode. Xcode provides interfaces to compilers that support several programming languages including C, C++, Objective-C, and Swift. For the Mac transition to Intel processors, it was modified so that developers could build their applications as a universal binary, which provides compatibility with both the Intel-based and PowerPC-based Macintosh lines.[63] First and third-party applications can be controlled programmatically using the AppleScript framework,[64] retained from the classic Mac OS,[65] or using the newer Automator application that offers pre-written tasks that do not require programming knowledge.[66]

There are 39 system languages available in macOS for the user at the moment of installation; the system language is used throughout the entire operating system environment.[153] Input methods for typing in dozens of scripts can be chosen independently of the system language.[154] Recent updates have added increased support for Chinese characters and interconnections with popular social networks in China.[155][156][157][158]

Mac OS X 10.4 Tiger was released on April 29, 2005. Apple stated that Tiger contained more than 200 new features.[202] As with Panther, certain older machines were no longer supported; Tiger requires a Mac with 256 MB and a built-in FireWire port.[96] Among the new features, Tiger introduced Spotlight, Dashboard, Smart Folders, updated Mail program with Smart Mailboxes, QuickTime 7, Safari 2, Automator, VoiceOver, Core Image and Core Video. The initial release of the Apple TV used a modified version of Tiger with a different graphical interface and fewer applications and services.[203] On January 10, 2006, Apple released the first Intel-based Macs along with the 10.4.4 update to Tiger. This operating system functioned identically on the PowerPC-based Macs and the new Intel-based machines, with the exception of the Intel release lacking support for the Classic environment.[204]

With conda, you can create, export, list, remove, and updateenvironments that have different versions of Python and/orpackages installed in them. Switching or moving betweenenvironments is called activating the environment. You can alsoshare an environment file.

By default, environments are installed into the envsdirectory in your conda directory. See Specifying a location for an environmentor run conda create --help for information on specifyinga different path.

To automatically install pip or another program every time a newenvironment is created, add the default programs to thecreate_default_packages sectionof your .condarc configuration file. The default packages areinstalled every time you create a new environment. If you do notwant the default packages installed in a particular environment,use the --no-default-packages flag:

You can control where a conda environment lives by providing a pathto a target directory when creating the environment. For example,the following command will create a new environment in a subdirectoryof the current working directory called envs:

Conda does not check architecture or dependencies when installingfrom a spec file. To ensure that the packages work correctly,make sure that the file was created from a working environment,and use it on the same architecture, operating system, andplatform, such as linux-64 or osx-64.

Activating environments is essential to making the software in the environmentswork well. Activation entails two primary functions: adding entries to PATH forthe environment and running any activation scripts that the environment maycontain. These activation scripts are how packages can set arbitraryenvironment variables that may be necessary for their operation. You can alsouse the config API to set environment variables.

If environments are not active, libraries won't be found and therewill be lots of errors. HTTP or SSL errors are common errors when thePython in a child environment can't find the necessary OpenSSL library.

Conda itself includes some special workarounds to add its necessary PATHentries. This makes it so that it can be called without activation orwith any child environment active. In general, calling any executable inan environment without first activating that environment will likely not work.For the ability to run executables in activated environments, you may beinterested in the conda run command.

This setting controls whether or not conda activates your baseenvironment when it first starts up. You'll have the condacommand available either way, but without activating the environment,none of the other programs in the environment will be available untilthe environment is activated with conda activate base. Peoplesometimes choose this setting to speed up the time their shell takesto start up or to keep conda-installed software from automaticallyhiding their other software. 2b1af7f3a8
