Hi Luckylucy,
Well there's good news and bad news here - the GOOD news is that we have received reports of users successfully running LR on Macs via not just Bootcamp but also Parallels and other virtual OS emulation software.
The bad news is, if your computer is a few years old and cannot sufficiently run Bootcamp, it may not meet the minimum system requirements for Little Reader either.

We currently do not have any set timeline for when we will develop a Mac-native version of Little Reader, although we do intend to some time in the future.
Sorry for the inconvenience!
Shuki
