Hi rickky, by default MoI will use the Arial font on OSX. But you should have it by default, it's been distributed with every version of OSX since at least 10.5 if not before that.

Do you see any text at all in the viewport, like the name label in the upper left corner and the x/y/z labels in the lower left corner?

ok install Arial and it works
Thanks

Hi rickky, I'm glad that worked! You should normally have Arial already installed on your system though, it's been a part of the standard OS install for quite a long time now I think.

If you want you can also change the font that MoI uses by going to Options > General > "Edit .ini file" button and inside there find the [UI] section where you'll see:

[UI]
<.....>
UIFontName=Arial

You can change that to a different font name if you want.
