I'm a bit concerned as my outputted PDF from InDesign CS5 looks different on Mac. This has happened a few times. It seems as though sometimes the Mac does not draw the new version of the PDF, which I have always assumed is because of a Solid State Drive (SSD). I'm not 100% sure this is correct, but I guess I can rename a document to find out.
Does anyone know of any other reason as to why this may happen? Sometimes it seems as though parts of the PDF update but other parts don't. Sometimes when I export from Illustrator CS5 it shows all of the layers even the turned off layers.
I'm really concerned that one day a printer will print it in an odd condition.
