Hi!
About your list of open PDF readers for mac: MuPDF isn't available for Mac OS X. Vindaloo hasn't been touched by it's author in the past 5 years, and the binarie that he offer on his website is only a ppc version.
And can you explain to me how "preview" (the PDF viewer on MacOS) doesn't allow me "to control my own privacy and data"?
Cheers.
