Apple Seeds Second OS X 10.10.4 Yosemite Beta to Developers, First Public Beta Version

os_x_yosemite_round_iconApple today seeded the second beta of OS X 10.10.4 to developers, approximately a week and a half since releasing the first 10.10.4 beta and nearly three weeks after releasing OS X 10.10.3 with the Photos for OS X app to the public. Alongside the new developer beta, Apple also released the first public beta version of OS X 10.10.4.

Developers can download the new beta, build 14E11f, through the Software Update mechanism in the Mac App Store or through the Mac Developer Center.

OS X 10.10.3 introduced several consumer-facing changes including the new Photos for OS X app, a redesigned emoji picker, new diversified emoji, and more, but OS X 10.10.4 appears to be an under-the-hood update that brings performance enhancements and bug fixes.

The first two updates to OS X Yosemite, OS X 10.10.1 and OS X 10.10.2 were also minor behind-the-scenes updates that improved performance through bug fixes and enhancements.

They are supposed to be California places.

Is there a place in California called "We just about finished ironing out the creases and now we're going to start the cycle all over again because we can't recognize that the one year cycle isn't working"?

If there is then Apple need to trademark that pretty damned quick.
