[DFTB-Plus-User] Issue installing dftplus through mamba

[Bálint Aradi]

Dear Alejandro,

we do not have any Conda packages for osx-arm64 yet. Lacking the 
appropriate hardware (most of our developers work under x86_64/Linux) we 
also do not have much experience with porting our code to this 
architecture yet.

If you are an experienced Mac user and are willing to help us to set up 
according Conda recipes, your help would be welcome. The first thing 
would be probably to compile DFTB+ from source on your device. If this 
is successful, we can then try to set up a Conda recipe for osx-arm64 
based your experience.

Best regards,

Bálint
