Right on schedule, Apple has released the sixth preview of the upcoming OS X Yosemite to developers today. This new seed comes two weeks following the previous release, and it likely continues to bring performance enhancements, interface tweaks, and bug fixes. We’ll be updating this post with the changes in Preview 6 as they are discovered. If you find something new, you can let us know at tips@9to5mac.com. The release version of Yosemite is currently scheduled for the later half of October, and it will ship separately from iOS 8, which is not seeing a new beta today. Here’s what’s new:
