macOS Tahoe 26.0.1 — PDFs from Illustrator showing missing beige backgrounds / faint text in Preview

Question

Hi everyone,

After updating to macOS Tahoe 26.0.1 on my MacBook Pro (M4 chip), I noticed a major visibility problems when I recently received a PDF file.

Certain beige or light background sections and text disappear completely when the file is viewed in Preview or Chrome. The missing areas only appear if I drag a selection box over them. I've tried to print the file to PDF as I've read this could help but no luck. I have read this problem has been talked about since March. Is there a fix?

@Gho123 you are correct, it's ongoing issue. A work-around is to open the file in Adobe Acrobat Pro, which continues to render these PDFs correctly. If you’re sharing PDFs with others, consider flattening transparency or exporting with solid backgrounds from Illustrator to improve compatibility. For dire circumstances, you could roll-back to a version that this bug doesn't show up
