I was looking for a long time for a pdf previewer like that for latex. The automatic resize feature is especially nice. Thanks for this new app.
There are some problems, though. In Texniscope, when a document is reloaded, not only the page is preserved but also a position in this page. It is inconvenient that PDFView jumps at the beginning of the page, especially, if you edit something in the bottom of the page and so, you have to scroll down to see the result.
I also was not able to make pdfsync work. Does it work for intel macs? There seems to be a problem with pdfsync in texniscope for intel. In my case, PDFViw does not even complain if the respective *.pdfsync file does not present (and it's presence does not change this behaviour). Texniscope has complained that "the document does not have a sycronization info" in this case.
