Skim is in the end a viewer for PDF, we just also provide a facility to view postscript, including eps, as PDF. It is not interpreted as an image format, Skim is not an image viewer. And this always draws on a white page brackground. BTW, that is a display fact, that we cannot even change (Apple's PDFKit draws the background and allows no customization). BTW, even PDF does not have a page background from itself. it is just always drawn by viewers. That is not a bug, it is the way it is drawn.

I am able to confirm the state of the file in Adobe Illustrator.
My previous workflow was to open .eps files (with no background) in Apple's Preview App which respects the no-background when the file is saved as a .pdf file.
Unfortunately I have upgraded to macOS Ventura 13.1 to discover Preview will no longer open .eps files.
I was suggested your App as a substitute for Preview by someone in Apple's Community forum. It does have the option to open .eps files and save them to .pdf, but unfortunately it seems to add a background to the bounding box of the .pdf.

I have done further tests both exporting and saving .eps files to .pdf, and do not know why but the files are now saving correctly with the background transparent.
A mystery! 🥹
