Revealed on stage at WWDC, iOS7 is billed as being “the biggest change to iOS since the introduction of the iPhone.” It’s meant to be cleaner, simpler, and showcase the liveliness of the phone experience. Developers can now interact with it and see how they can integrate features like the Control Center, understand how multitasking can be used, and utilize services like Airdrop, the new Photo app, and even check out the improved Siri.

For those developers interested in checking out the newest operating system for the Mac lineup, Apple’s website now has Mavericks available for download.

The newest version of OS X, Mavericks gives laptops and supported devices Finder Tabs, multiple display menus, on-screen notifications, and even iBooks support. Apple says that Mavericks is its most powerful operating system and the most power efficient.

Both versions can be downloaded from Apple’s Developer website.
