LyX ⇒ PDF opening in Windows, but not on Mac

[kalsarikanni]

Hi,

I've had a look through the forum, and haven't found anything on this.

I've just finished writing my thesis with LyX on Windows, and exported it to a PDF with no problems. However, my supervisors can't open the PDF on their Macs using Preview. Preview says that it cannot open the file because it is damaged.

I've broken the file down into sections, and each chapter can be read individually on both Macs and on Windows. My thinking is that this may be something to with the bibliography at the end causing problems.

Ideas? Suggestions?

Thanks,

Jon

Hi Jon,

welcome to the board!

If it's a PDF format and compatibility issue, you could use another PDF minor version. Perhaps check with a PDF reader, which PDF format version is used: 1.4, 1.5 or another.

You can adjust the minor version produced by pdfLaTeX this way, in your document preamble:

Code: Select all

\pdfminorversion=5

Hi,

Thanks for the response, Stefan.

After playing around a bit, I reckon this is actually something to do with the size of the document. It's around 400 pages when compiled, and with around 50 high-res images that I made to the minimum resolution of the journals I have submitted to (~1200 dpi). This would explain why the chapters can compile individually on a Mac but not when together in a single document, since the Macs I have tried are a lot less powerful.

So, I guess I should figure out some way of compressing it when exporting it, or just export it normally on a PC and then use Acrobat to reduce the file size.

Cheers,

Jon

Hi Jon,

we had a question regarding reducing PDF file size here: Lyx document - smaller PDF file.

Perhaps one of the possibilities I listed there might be useful for you.
