Apple Rolls Out Release Candidates for Major OS Updates: iOS 18.4, macOS 15.4, and More

Apple has released the first release candidate (RC) builds of iOS 18.4, macOS 15.4, tvOS 18.4, watchOS 11.4, and visionOS 2.4 to developers. These RCs follow the fourth beta releases for each OS, which were seeded on March 17th. Typically, an RC build is the final phase of a beta cycle before a public release. The builds include various updates and improvements across multiple Apple platforms, such as new features in Image Playground, priority notification adjustments, support for Apple Intelligence, and enhancements to CarPlay and Apple News+. Apple also recommends that users avoid installing beta software on primary or mission-critical devices due to potential bugs and data loss risks.
