It's my first time to write latex with Mac os (or in fact, using Mac os in general) and unlike with Windows I'm having some trouble viewing my output files. I'm using texmaker.
I would like to have either dvi or pdf viewer constantly open and auto-refreshing when I save changes or convert them to latex. I was told that Skim application should do the job, but I always have to close the dvi/pdf and re-open it for Skim to refresh my changes.
Any suggestions or advices how to handle this properly? This might seem like a small problem, but when I save and view my changes constantly it is really painful (and time consuming) to always close the pdf/dvi viewer, re-open it and then scroll to the correct location.
Thanks for all the help in advance.

simpdftexfor producing the PDF, no viewer will be able to refresh, as that script always moves the previous PDF to a temporary location, so the PDF viewer program is not able to notice changes. – egreg Jun 22 '12 at 13:32
