I always use to separate or extract files by printing to pdf on windows, but Mac doesn't provide the print to pdf option. I see the pdf drop down menu on the bottom left and when I click on that it doesn't give me the option to extract files. My main question is: How do I separate/extract files to single pdf's?
Mac does not support 'Print to PDF' option.
You can use Acrobat to separate pages to single PDF.
