I've some fonts in different weights (thin, regular, bold etc.) that work regularly for example with Libreoffice on Linux Debian. The menu offers me the possibility to choose the desired weight.
Installed with Librofont on a MacBook, the fonts instead show the generic family name and I don't have the possibility to choose the weight. Is there a trick to solve the problem? Or have I to change some parameters in the font names (for example "preferred family") within the font itself?
Thanks

There is a font named Libro, but I can’t find any app called “Librofont.”
I don’t know exactly what you mean by “show the generic family name.”
Especially, you don’t say exactly what fonts you are talking about and where you got them.
Broadly speaking: a font installing OK on one operating system will not necessarily install correctly on a different operating system. Linux, macOS and Windows will each care about some different things.
There is no simple “trick” to solve the problem. People actually study and learn about all the details and issues around font naming. I have done entire presentations on the subject, although none in recent years.
Here’s a message thread on the topic by Adam Twardoch. It is getting a bit old, and the MS Word 2011 problems mentioned are no longer problems, I don’t think. But at least it gives some idea of the complexity: https://forum.fontlab.com/fontlab-studio-tips-and-tricks/font-family-naming-in-fontlab-studio-5/
Perhaps somebody has a more current version of this sort of document?

This is probably due to the ambiguity of the classification, on which I ask the forum for clarification.
In fact, for the Regular the weight class is Book, 400 and the Style map Regular; for the Medium the weight class is Medium, 500 and the Style Map still Regular. Can't this confuse programs that use the font? And how can the problem be solved?

The program TextEdit has a very complete support of fonts and features. You can use it for comparison, what LibreOffice lacks. E.g. Helvetica Neue is a font family (.ttc) with 14 style combinations supported in TextEdit but only regular, bold and italic in LibreOffice.
