[Tex/LaTex] Live-Preview of LaTeX on OSX

live previewmacpdf

I use the following to live-preview my LaTeX files:

latexmk -pvc -pdf my_file.tex


However, in OS X, Preview only updates when you bring it into focus (e.g. you click on the the window). In many ways, this detracts from the experience of having a live-preview.

Are there any PDF viewers in OS X that are particularly well suited for live-preview?

If you do your editing in Emacs (see TeX.SX's review and a binary .app for OS X), you can activate auto-revert-mode in the PDF preview buffer. Each time the PDF changes, the change will be reflected in the window without you moving focus.
