I have a Mac Classic application that has been running in the field for well over a year now without issues, however recently some users have upgraded to OSX Sierra and have reported a problem. I utilise a PDFView component to preview the results of some reports (which are generated in HTML, and then converted to a PDF file using WKHTMLTOPDF), and users can then either print or export to PDF; the problem is that on Sierra the printed or PDF-exported results are shrunken on the page and only the first page of results are printed / exported. For this process I simply call "ThePDFView.Print(usePDFPrintInfo)".
This approach has worked fine on previous OSX versions, so I am unsure if this is a Sierra issue - as it seems odd to me that a well-formed and correctly-appearing PDF file can somehow be mangled in such a way - or if it is an issue with Xamarin for Mac that has been solved in recent months (as the version 'in the field' has been compiled with a version of Xamarin for Mac that is at least a year old).
So.... has anyone experienced this? Is this something that could well be simply addressed by converting my application to the Unified API and compiling with the most recent Xamarin for Mac / Mono / Xamarin Studio? I would really love to hear, especially, if someone can reproduce this issue on a simple Xamarin Mac app on Sierra to see if it's a general problem.
