All download files are mirrored at https://dealii.org/downloads/

The dealii-9.6.0-sequoia-arm64-clang16 image is 7.6GB large (due to the inclusion of the VTK library).

To regenerate the image, you should run the following command on the directory where you downloaded the files (not the signatures, i.e., not the files ending in .asc):

cat dealii-9.6.0-sequoia-arm64-clang16-part-* > dealii-9.6.0-sequoia-arm64-clang16.dmg

and you will end up with the final image file.
