A command-line utility to install any recent version of Unity.
Currently only supports macOS (Intel & Apple Silicon) but support for Windows/Linux is possible, PRs welcome.
Download the latest release here. install-unity is a self-contained executable and has no dependencies.
Or you can install via Homebrew using sttz/homebrew-tap, see the tap readme for instructions.
Installing the latest release version of Unity is as simple as:
install-unity install f
Most commands take a version as input, either to select the version to install or to filter the output.
You can be as specific as you like, 2018.2.2f1, 2018.2.2, 2018.2, 2018, f or 2018.3b are all valid version inputs.
install-unity will scan for the available regular releases as well as the latest betas and alphas.
install-unity list
install-unity list a
install-unity list 2019.1
Will show the available versions and the argument acts as a filter. Without an argument, only regular releases are loaded and displayed. Add an argument including b or a to load and display either beta or both beta and alpha versions as well.
In case install-unity fails to discover a release, it's also possible to pass a release notes or unity hub url instead of a version to details and install:
install-unity details https://unity3d.com/unity/whats-new/unity-2018.3.0
install-unity install unityhub://2018.3.0f2/6e9a27477296
The command above will install the default packages as specified by Unity.
install-unity details 2018.2
Will show the available packages for a given version. You can then select the packages you want to install with the -p or --packages option. The option can either be repeated or the names separated by space or comma:
install-unity install 2018.2 --packages Unity,Documentation
install-unity install f -p Unity Linux iOS Android
install-unity install 2018.3b -p Unity -p Android -p Linux
By default, install-unity will download and install the Unity editor matching the current platform.
Use --platform macOSIntel to download and install the Intel editor on Apple Silicon.
Use --platform macOSArm on Intel to download the Apple Silicon editor.
install-unity can be used in a two-step process, first downloading the packages and then later installing them without needing an internet connection.
install-unity install 2018.2 --packages all --data-path "~/Desktop/2018.2" --download
Will download all available packages to ~/Desktop/Downloads together with the necessary package metadata.
install-unity install 2018.2 --pacakages all --data-path "~/Destop/2018.2" --install
Will install those packages at a later time. Simply copy the folder together with the install-unity binary to another computer to do an offline installation there.
You can download and install only a subset of the available packages.
To select a Unity version from all the installed ones, use the run command.
install-unity run f
Will open the latest version of Unity installed.
You can also use the path to a Unity project and install-unity will open it with the corresponding Unity version.
install-unity run ~/Desktop/my-project
It will only open with the exact version of Unity the project is set to. You can optionally allow it to be opened with a newer patch, minor or any version:
install-unity run --allow-newer patch ~/Desktop/my-project
You can pass command line arguments along to Unity, e.g. to create a build from the command line (note the -- to separate install-unity options from the ones passed on the Unity).
install-unity run ~/Desktop/my-project -- -quit -batchmode -buildOSX64Player ~/Desktop/my-build
By default, Unity is started as a separate process and install-unity will exit after Unity has been launched. To wait for Unity to quit and forward Unity's log output through install-unity, use the --child option:
install-unity run ~/Desktop/my-project --child -v -- -quit -batchmode -buildOSX64Player ~/Desktop/my-build
To start a basic Unity project, use the create command. The version pattern will select an installed Unity version and create a new project using it.
install-unity create 2020.1 ~/Desktop/my-project
The project will use Unity's default setup, including packages. Alternatively, you can create a minimal project that will start with an empty ´Packages/manifest.json`:
install-unity create --type minimal 2020.1 ~/Desktop/my-project
install-unity v2.12.1
