Apple also provides new OS X 10.9.4 seed to non-developer AppleSeed testers
We noted yesterday that Apple released OS X Mavericks 10.9.4 build 13E19 to developers, and now users of Apple’s customer AppleSeed software testing program are reporting that the seed has also gone out to those non-developers. 10.9.4 is a bug fix release without major feature enhancements, and it is unclear when it will ship publicly to all Mac users. This fall, Apple will ship OS X 10.10 Yosemite with a refreshed user interface, new Continuity features, and improved applications.
