I haven’t seen any updates to the official retina.js, but I’m happy with my slightly modified version here. I just commented out the two lines that I mentioned in my original post. The plugin is working on my blog on my retina MBP and I can’t imagine why the code was in there (the developer isn’t sure either). I expect this will be corrected in the original retina.js at some point, and maybe there’s some special case that my blog hasn’t exposed, but for now I’m happy with what I have. I hope this helps.
Sorry, I just found the reference to retinajs.com in the advanced settings tab. I hadn’t realized this code was included unmodified from the original source. This issue is addressed here if anyone else is curious.
