Download and install RoboHelp on macOS

Open the installer file that you downloaded from the Adobe website.

Navigate to Set-up.dmg inside the product folder.

Double-click Set-up.dmg file. The .dmg file mounts in two places: on your desktop and in the Finder sidebar under your hard drive. Clicking either one of these opens the .dmg file.

Navigate to the Adobe RoboHelp folder using the file browser and simply click on the Install.app file located inside the folder.

To install the Install.app file, drag it into your Applications folder and launch it.

Once the installer window opens, sign in with your Adobe ID and password if you are not already signed in.

Follow the installation prompts until the installation is complete.
