You can always find the latest version of Legantoo for macOS in the download area of the project homepage.
Download the Legantoo dmg image to your computer. You will then find the file in the „Download“ folder, if you have not set anything else here.
Now click on the image file. This opens a folder in which the Legantoo program file is located. Highlight them by panning the VoiceOver cursor and copy the file to the clipboard by pressing Command + C. Then navigate to the „Applications“ folder. This is the directory where all your programs are stored. Insert the Legantoo program file here by pressing Command + V. Legantoo is ready to go on your Mac.
