Called as “a bag of hurt”, Blu-ray has always been die-hard trouble for all the Mac users. Every updates and release events brought great surprise, as well as one more time disappointment. The Blu-ray playback capability is what we need urgently and hope to find even from the third party software. According to some reviews from authoritative websites such as Macworld and Tuaw, we could figure it out that Mac Blu-ray player out of Macgo tops the list. It is the first Blu-ray player software for Mac in the world and already accepted by a large number of Apple fans. All Blu-ray Disc, Blu-ray files, and Blu-ray folders (BDMV folders) can be perfectly played on MacBook Pro, Air, Mac mini, iMac, Mac Pro with OS X 10.5 to 10.8, even the latest Mavericks. What great news!

Updates to the Mavericks beta have been pushed out systematically over the summer, and Apple will ship the OS to the public this fall. The September 10th event will focus on iPhones, and a separate media event is expected to take place next month. Apple could release Mavericks at any time this fall, but it’s likely that a release date will be given alongside new iPad/Mac hardware in October.
