Exporting typeface overwrites old!

I am editing an existing typeface which I have imported, but when I export it writes over the original typeface. I want to keep the original as it is and have my edited version as an alternative! Can anyone help? :slight_smile:

I am exporting into Macintosh HD > Library > Fonts so I can test in InDesign. It’s the only way I can get the font to show up.

If you want to create two different family, you need to change the Family Name in [Font Info > Info ]
If you want to see both in the same place (same family) in InDesign you need to change Style Name in [Font Info > Export]

Thanks for your reply! In Font Info > Info, this is what I can see. I don’t see anywhere to amend any details?

Check the font and style name above the metrics icons.
