Apple is letting the general public test out its two latest operating systems, one for mobile devices and one for desktop and laptop computers.

Starting Thursday, anyone can download the iOS 9 and OS X El Capitan betas, according to CNet.

This is the first time that Apple is making a major update beta available to non-developers for mobile devices.

Apple first announced iOS 9 at their Worldwide Developers Conference (WWDC) in June. iOS 9 will power both the iPhone and iPad. The final version of iOS 9 probably will not release its final version until this fall, but now anyone can download the beta version of it.

Apple recently released a minor update to iOS 8 with iOS 8.4. iOS 8.4 gave users their first taste of Apple's new streaming music service Apple Music. Most iPhone and iPad users will choose to wait until all bugs and improvements are made to iOS 9 before they install it on their devices. However, some users might want to install the beta right away.

Mac owners will also be able to gain early access to a beta for the next operating system. OS X El Capitan's beta is now available to all interested Mac owners. A new feature in El Capitan include an improved Spotlight search function, which allows users to search for information like the weather, news and e-mails.

With El Capitan, Macs will be able to display two apps at once on the same screen using a function called "split view." Apps will start faster and switching between them will be quicker too.

The iOS 9 beta could come with bugs and it could make iPhones and iPads behave differently than users are accustomed to. Before installing any beta, users are encouraged to fully backup their devices.

The final version of iOS 9 will feature an improved Siri and search window. Also, for the first time, Apple Maps will feature transit directions in the app and battery life is expected to improve.
