The conda isce2 package is not available from conda-forge for the "osx-arm64" architecture.

It is not possible to install isce2 from conda-forge on an M1/M2 Mac because the package is not available for "osx-arm64".

 conda install isce2 mintpy

Hi, So is there a way to install isce2 on M2 mac? I've tried this installation guide: https://github.com/lijun99/isce2-install but failed as well. These packages basemap openmotif openmotif-dev xorg-libxft could not be downloaded from conda-forge. And I think there are also some compiling error occurred. Thank you!

The basemap package is obsolete and can be removed from the list. I installed the openmotif and other X11 packages on my M1 Mac with MacPorts and I managed to get ISCE2 to compile with the cmake system. I forget all the packages that I had to install with conda.

I followed the step here: https://github.com/lijun99/isce2-install with MacOSX with Anaconda3 and homebrew: Apple Silicon It worked satisfactorily on my M2 Mac.

Great to hear you were able to build ISCE2 on your M2 Mac. I am glad to see that @lijun99 has updated his installation instructions.
