Option C: Run simulations with nextnanomat using Wine

Attention

Instead of using the nextnanomat GUI on MacOS, we strongly recommend to use nextnanopy since it runs MacOS-native executables and also provides methods to modify input files and interact with simulation output.**

This documentation is for those who nonetheless wish to use the GUI nextnanomat to run simulations.

The nextnanomat GUI is programmed in C# and uses the WinForms Framework for its frontend, it is developed on and optimized for Windows. On macOS, you have to install either Wine or Mono to run nextnanomat.

Status: We successfully tested running nextnanomat with Wine on macOS (ARM and Intel) and thereby recommend to use Wine for users who wish to run nextnanomat or nextnano.NEGF. However, Wine stable is compiled for Mac Intel and requires Rosetta 2 to run on an ARM Mac.

Note

Wine stable does not pass the MacOS Gatekeeper check and is claimed to be disabled on 2026-09-01.
