MicroDicom is not available for Mac but there are plenty of alternatives that runs on macOS with similar functionality. The best Mac alternative is OsiriX. It's not free, so if you're looking for a free alternative, you could try Horos or Weasis. If that doesn't suit you, our users have ranked more than 10 alternatives to MicroDicom and 11 are available for Mac so hopefully you can find a suitable replacement. Other interesting Mac alternatives to MicroDicom are Miele-LXIV (Free, Open Source), 3DimViewer (Free, Open Source), AMIDE (Free) and dicompyler (Free, Open Source).
Weasis is a multipurpose standalone and web-based DICOM viewer with a highly modular architecture. It is a very popular clinical viewer used in healthcare by hospitals, health networks, multicenter research trials, and patients.
Miele-LXIV is a DICOM workstation, viewer and more. The project started in November 2014 as a fork of the popular open source 32-bit project OsiriX, but it has been modified to become a 64-bit application and to remove many of the limitations of the 32-bit version.
Ginkgo CADx is a multiplatform (Windows, Linux, Mac OSX) DICOM viewer and dicomizer. Ginkgo CADx is based in free software (Open Core), so you are free to use and distribute the Open Source version with no cost.
