Apple issues release candidates for iOS 15.7.8, iPadOS 15.7.8, macOS Big Sur 11.7.9, and Monterey 12.6.8

While a release candidate is expected for major software update releases, especially for current-gen operating systems, sometimes they emerge if Apple is bringing out an update for its older operating systems. On Tuesday, Apple brought out four more release candidates impacting earlier operating system generations.

The existence of release candidates means a formal update will be available for each of the four operating systems in the near future.

Apple does occasionally make updates to its earlier operating systems, which are commonly used with devices that cannot support the latest operating system versions. These updates tend to consist of security fixes and compatibility additions, rather than handling new features.

The four release candidates, and build numbers, are:

• iOS 15.7.8 and iPadOS 15.7.8 — 19H364
• macOS Big Sur 11.7.9 — 20G1426
• macOS Monterey 12.6.8 — 21G725

Developers enrolled in the beta program can pick up the newest versions via Apple Developer Center or update their device in Settings. Public beta participants can usually get the latest versions soon after the developer releases them through the Apple Beta Software Program.

AppleInsider and Apple strongly suggest users don't install beta operating systems or other beta software on "mission-critical" or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
