It appears that OS X Yosemite may be heading for a late October launch. Given that OS X Mavericks was released around the same time last year, this is not an unreasonable time frame. It also seems that the final release will follow a series of developer previews that will conclude at the end of September, followed by a Golden Master in mid-October. From 9to5Mac:
Apple plans to continue releasing OS X Yosemite Developer Previews every two to three weeks until a final Developer Preview is seeded on September 29th, according to the people. Apple is then expected to finish up work on Yosemite in early October and release a golden master build around October 10th, the sources said.
In addition to the release date for Yosemite, Apple is also apparently finishing work on a pair of new Mac products. First, a 12-inch MacBook with a Retina display, which is in line with reports from earlier this year. Second, a 4K-resolution product, either an iMac or new display, is said to be in production. It's not clear how the 12-inch MacBook will be branded, wither as a MacBook Air, a Pro, or something new.
As always, we won't know anything until Apple tells us. What are you most looking forward to in Yosemite, when it eventually does come out? Let us know below in the comments.
