Install the Sky Calendar on MacOS (Mac).

Because MacOS is trying to protect you from accidentally installing unknown and potentially harmful applications, you need to take a few simple steps to tell your Mac that the Sky Calendar is a harmless application that you trust before you start your Sky Calendar for the first time.

To do this:
  1. Launch the Finder to open the folder where you downloaded the Sky Calendar (usually the Downloads folder).
  2. Unzip the downloaded NK4Mac.zip file to create NK4.app.
  3. Move the NK4.app file (still in the Finder) to the Applications folder.
  4. Switch to Applications.
  5. In the application list, find the NK4.app file you just copied.
  6. Hold CTRL while double-clicking NK4.app. This window should appear:
  7. Click Open. Then the Sky Calendar should start.
  8. From now on, your Mac will work with Sky Calendar like any other program.
Note: This procedure applies to MacOS 10.12 (Sierra) and above, there may be slight variations in the lower versions.
