Reply To: Out of Memory message

David, thank you very much for your answer! While the book is quite big (over 1200 pages with text, EPS and small TIFF files), the resulting PDF is just 32MB. Nothing shocking. I’ve just generated it with a MacBook Pro 2015, with just 8GB of RAM.
The same operating system (High Sierra), the same installation of InDesign CS6 (both cloned from the original installation from the original DVDs). The Mac Pro does seem to work fine with everything else. It can also generate smaller PDF files (for example, about one third or the above book).
Very strange. I suspect some memory issue because it has troubles only with big books, and sometimes it says that it can’t load one or more EPS files (nothing big – just wireframe Illustrator drawings, with text updated to CS6).
