Apple Ships Second watchOS 27.2 Release Candidate to Testers
The new build, 24S118, replaces the first watchOS 27.2 RC (24S5101f) and is available to developers and public beta testers.
Apple released a second release candidate build of watchOS 27.2 for developers and public beta testers on October 23, 2026, according to 9to5mac.com. The new build carries the number 24S118.
The second RC replaces the first watchOS 27.2 release candidate, build 24S5101f, which arrived earlier this week.
Apple has not detailed what changed between the two builds, so the specific fixes or adjustments in 24S118 remain unknown.
Testers on the developer and public beta channels can install the new build now. It follows the first RC by only a few days, an unusually short gap between release candidate builds.
Apple is expected to launch its wave of 27.2 software updates next week, likely early in the week, including iOS 27.2, tvOS 27.2 and iPadOS 27.2. The company has not announced a release date for watchOS 27.2.
