I use dual boot.

That´s right Dikloraine, Comictagger is the other solution. Althought it crashes frequently on my mac. Right now I keep fighting with comicvine plugin on calibre, trying to make it works properly.

Almost forget, Comicrack works flawless converting cbr to cbz, you can use it for that, so you can read on MyReadings.
