Quantgress has no macOS build yet
The person who submitted Quantgress only tested and declared a build for the other platform, so publik has nothing reviewed to walk you through here — a guessed set of commands would be worse than an honest no.
What you can do instead
- Check the Quantgress repository on GitHub for a community macOS build.
- Ask the maintainer to submit a macOS build through publik.
This is a limit of the phone and computer combination, not of Quantgress. Every other combination has a full guide.
