I recently bought an external USB2.0 bluray drive from amazon and have been pleasantly surprised. It works very well. It cost only $35.
I would like to backup some of my Bluray movies into my external hard drive. MacGo claims they can play the lossless audio through the Mac's HDMI port or thunderbolt. Is this really true? I thought Macs were not able to do that. Anyone with a newer mac want to try this software out. My iMac is from 2007 and cannot do this. But I am able to play blurays through my USB bluray drive and this software with lossy audio.
