To install on Mac we currently require a few things to be installed.
First step is to run this in your terminal, this will install Homebrew.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"The next step is to install the required libssl version using the following commands.
brew update && brew upgrade;
brew uninstall openssl;
brew install --force [email protected];
sudo ln -s /usr/local/opt/[email protected]/lib/libcrypto.1.1.dylib /usr/local/lib/libcrypto.1.1.dylib;
sudo ln -s /usr/local/opt/[email protected]/lib/libssl.1.1.dylib /usr/local/lib/libssl.1.1.dylib;The final step is to whitelist the Etterna directory, we cannot afford code signing and Apple forces it for the file system access we need to load NoteSkins and Songs.
sudo xattr -r -d com.apple.quarantine ~/your/path/to/EtternaYou path to Etterna is where ever you placed the folder inside of the DMG. If you copied it to your Desktop for example and renamed the folder, your path would be ~/Desktop/Etterna
For those that do not wish to compile the game on their own and use a binary right away, be aware of the following issues:
- Windows users are expected to have installed the Microsoft Visual C++ x86 Redistributable for Visual Studio 2015 prior to running the game. For those on a 64-bit operating system, grab the x64 redistributable as well. DirectX End-User Runtimes (June 2010) is also required. Windows 7 is the minimum supported version.
- macOS users need to have macOS 10.6.8 or higher to run Etterna.
- Linux users should receive all they need from the package manager of their choice.

In short — you can do anything you like with the game (including sell products made with it), provided you do not claim to have created the engine yourself or remove the credits.
