Apple Rolls Out Release Candidates for Major OS Updates: What to Expect

Apple has released Release Candidate (RC) builds of iOS 18.5, iPadOS 18.5, macOS 15.5, tvOS 18.5, watchOS 11.5, and visionOS 2.5 to developers as the updates near their public release. These RC versions are almost ready for launch but undergo final testing before being made available to the general public. The builds follow the fourth beta releases issued on April 28. Changes in these RC builds are not substantial, suggesting that the focus is primarily on performance improvements, bug fixes, and compatibility updates. Apple advises users against installing beta software on mission-critical or primary devices due to potential bugs and data loss risks. Testers should use secondary or non-essential devices and ensure they have adequate backups.
