Following Apple’s special event on Tuesday, the company confirmed that iOS 15 will be available to public on September 20.
However, developers and public beta users can now download the iOS 15 and iPadOS 15 RC (Release Candidate) through the Apple Developer website. The update is also being released as an OTA download for those already running iOS 15 beta on an iPhone, iPod touch, or iPad. The same applies to watchOS 8 and tvOS 15.
iOS 15, iPadOS 15, watchOS 8, and tvOS 15 will be available to the public on Monday, September 20. According to Apple, macOS Monterey will be released later this year — the date is yet to be announced, so the beta testing period continues.
