Hi @Anonymous,

Can you attach the resulting PDF? This will help me to answer your question more accurately.
For now I can suppose that:
- you are using SHX based text styles in your drawing
- the "boxes" around the text actually are notes, which AutoCAD places behind SHX text geometry to make text searchable in PDF (if you are saving DWG to PDF), the same "boxes" occurs when you print directly to the printer in AutoCAD for Mac.

If I'm correct, than you can set AutoCAD system variable EPDFSHX=0, than AutoCAD will not create "searchable" text notes and "boxes" around text should go away.
