The new OSX will be released this fall but a Mac OSX Yosemite beta is already available online. I don’t care much about the “wow” effect around the new Apple products, so I tested this new Operative System comparing the old OSX Lion 10.7.5 and the current Ubuntu Linux 14.04 LTS for the stuff I care: the UNIX and the Web performance part, because I fear the upgrade OSX dilemma.
