Hi Conley Evan
Thank you for reaching out to the Microsoft Q&A Forum.
I understand how inconvenient this situation can be, especially when you only have a PDF version of your design and need to make edits in PowerPoint.
Based on my research, PowerPoint for Mac can insert a PDF as an image or an object, but it cannot convert a PDF into an editable PPTX file. Because of this, the content inside the PDF may not open in a way that allows direct editing.
You might consider converting the PDF to PPTX using an external tool such as Adobe’s PDF-to-PowerPoint converter. After the conversion is complete, you can download the PPTX file and open it in PowerPoint to make your edits.
