As it has done almost every week for the last few months, Apple on Wednesday seeded a new build of the next update to 10.8 Mountain Lion on Wednesday. The latest version of the 10.8.4 beta comes with the curious numbering of 12E33a, the first beta in recent memory to have a letter designation at the end. The significance of the letter is unknown, but could be indicative of a last-minute revision. As has become usual, the release notes only ask developers to focus on graphics drivers, Safari and general Wi-Fi testing.
