Hi @Anonymous ,

Thanks for your posting. 

If the issue happens to only a few specific drawings, try to repair the dwg files through the AKN article below; 

• About Repairing Damaged Drawing Files. 

and if the issue happens to any files, try the solutions in the article below; 

• AutoCAD for Mac runs slow and freezes. 
• Reset to default setting. 

Thank you,
