free ebook reader for mac that can handle djvu?

[ertyu]

I downloaded a bunch but they all have epub and pdf as a basic option then ask me to pay for djvu or other formats. Either a reader app or a file format converter app suggestion would be much appreciated. I am willing to pay $1-2 for a converter, but these days I don't trust when the service will suddenly become subscription based (subscription-based services piss me off to no end). What is a versatile reader you guys use? Thanks

Calibre for free. It is a whole library management system that includes a universal ebook reader and works across platforms.
