OS X El Capitan is the upcoming twelfth major release of OS X
Apple Inc.'s desktop and server operating system for Macintosh computers.
It is the successor to OS X Yosemite and focuses mainly on performance, stability and security.
Its due to be released to the public today (September 30th 2015) and many of our customers are already asking if they should upgrade. Well, the long answer is yes. Whilst in Microsoft Land we often recommend against an upgrade especially as so many issues are generally related to upgrade, in Apple Land upgrades rarely break anything save for some low level device/fs drivers. As with OS X Yosemite, there will be changes, but nothing so severe that you'll be unable to use your device. Just like iOS9 it will take a little getting used to but its worth the effort. Apple will undoubtably continue to support Yosemite for the foreseeable future, but with El Capitan comes a new graphics layer called Metal, which is going to hopefully open the gates to really immersive gaming and high end graphics applications on the apple platform.
If you run into any problems with the upgrade, or usability after the upgrade, then don't hesitate to utilise your GEN Support Contract for assistance as we Fully Support OS X.
