Roberto Panetta has updated his International Space Station app for the Mac to version 2.1. It shows the exact position of the space station over the earth and lets you see it with your naked eye.
Version 2.1 is optimized for macOS Mojave. It also contains some minor bug fixes.
International Space Station requires macOS 10.11 or higher. It costs $6.99 and is available at the Mac App Store (https://tinyurl.com/ybjjyjnv).
