Apple on Thursday launched the first public betas of OS X El Capitan and iOS 9, giving the public an early glance at the operating systems before they officially debut this fall.

The company warns that because the platforms are in beta, some apps may not work properly. Before installing, users are strongly urged to make backups of their data in case problems arise with either apps or the operating systems themselves.

The betas are available through the company's Beta Software Program website for registered participants.

The new code should be based on third developer betas which were released on Wednesday alongside a new seed of watchOS 2. The El Capitan build contained known issues with two-factor authentication, restoring Time Machine backups for Mail, and importing iPhoto and Aperture libraries into Photos, among other bugs.
