The brand new OS X Yosemite is perhaps the most dramatic redesign of Apple's operating system to date. After some time using the biggest features in the new OS in a developer preview, I think Apple's on to something.
At this stage in the game, it's not fair or appropriate to give the new (very beta!) version of OS X a real evaluation. Some of the features aren't fully-formed, while others—ahem, iCloud Drive—seem barely present at all, at least not in the final form we were expecting.
Named after the California national park, Yosemite will be available later this fall, and end users will be able to sign up for a public beta program in the summer. As with Mavericks, the Yosemite update will be free.
In my Mac Pro review I lamented the state of 4K display support under OS X 10.9.0. In my conclusion I wrote: "4K display compatibility under OS X is still a bit like the wild west at this point". Compatibility was pretty much only guaranteed with the ASUS/Sharp 4K displays if you cared about having a refresh rate higher than 30Hz. Even if you had the right monitor, the only really usable resolution was 3840 x 2160 - which ends up making text and UI elements a bit too small for some users.
While I am a Linux guy at heart, I love OS X. After all, both Apple's operating system and Linux distributions are Unix-like. While Microsoft's Windows is relatively safe nowadays, I still feel safest on OS X or Fedora. Well, at least I did feel safe. While Linux remains rock solid, OS X and iOS have been dealt a huge blow from a trust perspective.
A German security company has released an unauthorized patch for Apple's OS X Mavericks that it claimed closes the hole the Cupertino, Calif. giant left wide open in the operating system's implementation of basic Internet encryption.
