Shulou(Shulou.com)11/24 Report--

CTOnews.com, November 6 (Xinhua)-- Apple's old operating system is updated regularly to fix security vulnerabilities. Apple also said that only the latest operating system updates can be fully protected.

Apple has not specified its security update practices before. This requires enterprising users and researchers to compare security patch instructions and CVE numbers to determine where they have been patched.

According to a new support document reported by Ars Technica, Apple said that only the latest operating system has the most comprehensive security patches. In older systems, vulnerabilities are still patched, but not all.

The purpose of this support file is to define the difference between software updates and upgrades, but information about security patches is also included. It briefly mentions that the old version of macOS is not as protected as the latest major system version.

For those who follow the industry, it will come as no surprise. Apple fixes serious operating system problems many years ago, but not every patch is widely available.

CTOnews.com learned that the best way for the average user to remain immune to vulnerabilities is to use the latest hardware and update to the latest available software. However, not every user can upgrade their operating system as soon as the latest and most major versions are released.

Some users will still stick to the old operating system. For example, as the device ages, it loses the ability to run the latest software, and official support for new upgrades is abandoned.

For devices that can run the latest software, users sometimes decide to wait for a stable version or for work-related applications to become compatible. Even if a new operating system has been launched, Apple tends to release a small number of support updates for the old system.

For example, Apple recently released the official version of iOS 15.7.1, which includes a series of security fixes and patches. However, this update covers fewer vulnerability list entries than iOS 16. 1.
