MicroDicom DICOM Viewer is an application for Windows. You can still use it on a Mac, because Windows applications can run on macOS with Wine. There are two ways to do it, and we made a video for each of them that shows every step.
With Wine (free)
Wine is free, open-source software. Download the macOS package from our Downloads page and follow the video.
With CrossOver Mac (paid)
CrossOver Mac is commercial software based on Wine. It is paid, but it has a free trial.
If something does not work on your Mac, please write in our forum or contact us.
