Apple on Thursday seeded the first beta of OS X 10.10.4 to developers. The new seed comes just over a week after the public release of OS X 10.10.3.
The new beta, (build 14E7f), can be downloaded via the “Update” tab in the Mac App Store, or via the Mac Developer Center.
The seed notes for OS X 10.10.4 merely states, “The OS X Yosemite 10.10.4 update improves the stability, compatibility, and security of your Mac.” So, we don’t know at this time what fixes or additions have been made to the operating system. We’ll let you know as soon as we find out anything.
