As expected, Mac OS X El Capitan is coming tomorrow

September has been a great month for Apple fans, with updates to all major operating systems. First it was iOS 9, then watchOS 2, and now Mac OS X El Capitan will be officially available tomorrow

The new OS brings with it some features to make working with your Mac faster, simpler and smarter. Split View, which first made its appearance on iPads in iOS 9, will be available in OS X El Capitan. An updated Mission Control shows all open windows in a single layer with one swipe, making it easy to view what's open. 

Spotlight improvements will make it easier for Mac users to find documents and information. El Capitan will now provide results for weather, transit information, web video, stocks and sports, all accessed through natural language queries. 

Mail gets updated and will now add suggested events or contacts to your calendar or contact list with a click. The gestures you're used to in Mail on iOS 9 will now work the same on Mail on your Mac. And if you're a fan of the new Notes app on iOS 9, you'll be glad to know that the OS X El Capitan Notes app has been given compatibility. Pretty much all of the features except for drawing have come over to Notes on the Mac. 

In the Photos app, we'll begin seeing editing extensions so that your favorite third-party editing tools will be part of Photos. Safari gets a few updates, letting you pin favorite websites to the left side of the the tab bar. 

All-around performance should be much improved, with the biggest updates coming from Metal, which is designed to speed graphics rendering. 

If Apple is true to its plan, you'll probably see OS X El Capitan at about 10 AM PT tomorrow (September 30). Stay tuned for some articles about the features of OS X El Capitan.
