Apple Security Update: Confirmed that only the latest OSes are fully parched

Apple Security updates were released this week in a document. It made its terminology and guidelines for software upgrades and updates more clear. Most of the information isn’t new, although the company provided one clarification. 

Its updating procedure, which it had not previously specified: Apple asserts. However, only devices using the most recent major operating system versions should have complete security. It regularly delivers security updates for different versions of macOS and iOS.

Announcement of New Features in Apple

Apple mentions important OS updates. It can include many new features and user interface enhancements. Also, “upgrades” refers to the text. Updates, however, refer to more frequent patches. These updates often correct problems and eliminate security threats. 

Thus, an upgrade would go from iOS 15 to iOS 16 or from macOS 12 to macOS 13. An update changes from iOS 16.0 to 16.1, macOS 12.5 to 12.6, or 12.6.1.

It does not fix all known security concerns in previous versions (for example, macOS 12). Further, it is due to dependence on architecture and system changes to any current version of macOS (for example, macOS 13).

Apple Security Updates

In other words, the last upgrades will not provide security-related updates for Apple’s operating system. It will only provide patches for security flaws for the most recent advancements. Apple is conscious of the recent launch of macOS Ventura.

Apple now provides security updates for macOS 11 Big Sur and macOS 12 Monterey. It has offered security fixes for earlier iOS versions of devices and cannot install the most recent patches.

It validates a conclusion that unaffiliated security researchers have long held. But Apple never made that information public. The CVEs that various macOS have addressed. And iOS upgrades have been tracked for years by Joshua Long.

Joshua is the principal security analyst at Intego. He typically learns this when the most recent OS versions include bug fixes. Older versions that are still technically “supported” may take months to repair.

Because Apple has become a tendency to stop supporting older Mac and iDevice models, most updates are significant for Mac users as it has somewhat increased for older Intel Macs in recent years. It suggests that specific security updates, but not all, apply to a new group of devices each year. 

We can use software to make the most recent OS versions compatible with older hardware. Similar to the OpenCore Legacy Patcher, it has its limitations and requirements and isn’t always simple to use.

In most cases, this won’t significantly affect your choice of whether to upgrade or stop using an older Mac. Most users of current Big Sur or Monterey installations should protect against most high-priority attacks using the most recent version of Safari. Furthermore, Apple’s documentation does not alter how it upgrades older software.
