Apple just released the latest update to Mac OS X, and there's a lot of good stuff to explore. There's also a few crucial security and stability fixes, so if you haven't updated your OS in a while, now would be the time.
I'm most excited about the new Photos app. You know how much I love photography, and I know that you'll love the new changes to the photo editing system for Macs. The Photo app, which you can find in the app store, will replace the iPhotos program as the default Mac photo manager. Aperture is also going away.
But don't be alarmed at the apps going away. Apple is giving back plenty more. For starters, there's over 300 new diversified emojis, improved screen-sharing capabilities and fixes to the issues that were causing Bluetooth gadgets to disconnect.
There's also improved compatibility with "captive Wi-Fi network environments" and Wi-Fi networks in general. One of the biggest updates, besides the Photo app, is the changes to the Safari browser. Safari is now prevented from saving "website favicon URLs used in Private Browsing" as well as general security and stability fixes.
