That issue report is a duplicate of https://github.com/darktable-org/darktable/issues/4384 https://github.com/darktable-org/darktable/issues/4384 And as mentioned in the issue you linked it isn't a bug but a feature request to support macOS hotkey conventions. There is a workaround in the meantime documented and a suggestion on how to address the feature request (that requires refactoring of the codebase) on the non-dupe ticket. Since this is libre software anyone can improve the code along those lines and send a merge request or even commission a developer to do that refactoring; the DarkTable maintainers _didn't_ refuse contributions nor marked it as wontfix however that doesn't mean that the maintainers have development-time to spare in that macOS-specific code. On the other hand if not using macOS hotkey convention is an example of it being "unusable" then I guess it is really great for something most people don't pay a penny or contribute otherwise for.
