TOKYO (MacHouse) – MKVToolPack is back! MacHouse‘s 3rd-most-selling software title is upgraded with a totally new user interface. MKVToolPack 2 looks better, and users should find it much easier to use. MKVToolPack 2 comes with a better progress bar, which smoothly works without letting System’s rainbow wheel take over the entire application. And abort the export process whenever you want (unless you are under the UnpackAll component).
