Install using the Toolbox App
The JetBrains Toolbox App is the recommended tool to install JetBrains products. Use it to install and maintain different products or several versions of the same product, including Early Access Program (EAP) releases, update and roll back when necessary, and easily remove any tool. The Toolbox App maintains a list of all your projects to quickly open any project in the right IDE and version.
Install the Toolbox App
Download the disk image .dmg from the Toolbox App web page.
Mount the image and drag the JetBrains Toolbox app to the Applications folder.
After you run the Toolbox App, click its icon in the main menu and select which product and version you want to install.
Log in to your JetBrains Account from the Toolbox App and it will automatically activate the available licenses for any IDE that you install.
Install AppCode manually to manage the location of every instance and all the configuration files. For example, if you have a policy that requires specific install locations.
Download the disk image .dmg.
Mount the image and drag the AppCode app to the Applications folder.
When you run AppCode for the first time, or after you have upgraded it from a previous version, some steps are required to complete the installation, customize your instance and start working with the IDE.
