## Is an Immediate Upgrade Recommended?
While the new features in iOS 18, iPadOS 18, and macOS 15 Sequoia are thrilling, not everyone may feel compelled to upgrade right away. Historically, major operating system updates (those ending in “0”) can come with flaws and reliability issues that are resolved in later releases. If you value stability and dependability over new features, it might be wise to wait for a few bug-fix updates before transitioning.

– **iPadOS 17.7**
– **macOS 14.7**
– **macOS 13 Ventura Security Update**
– **Safari 18 Update** (compatible with macOS 13 and 14)
These updates ensure that users opting not to upgrade to the latest operating systems can still receive essential security patches, preserving their devices’ safety without confronting potential bugs in the new software.
## Apple’s Dedication to Security Updates for Older Devices
Apple has consistently demonstrated a commitment to delivering security updates for older macOS versions, typically supporting them for approximately two years following the release of a new version. This approach enables users to use their devices securely without feeling the urgency to upgrade promptly.
With regard to iOS and iPadOS, Apple has traditionally ceased updates for older versions once a new iteration is launched. However, this policy shifted in **2021** when Apple began offering **security-only updates** for previous iOS versions. This adjustment was designed to accommodate users apprehensive about installing new operating systems that might contain bugs.
### How Long Will Support for Older Devices Last?
