During the Worldwide Developers Conference yesterday, we found out all about the improvements and features that iOS 9 and Os X 10.11: El Capitan will bring to the table. To help shape the upcoming operating systems Apple are looking for Beta testers! All you need is an Apple ID to get involved, so no need to be in the Apple Developer program to get access. You will get to test the new software before anyone else and report any issues as you find them. All of this should of course mean a more stable and smooth release, hopefully in the not to distant future - Click Here to sign up
