Apple has unveiled macOS Sequoia (version 15), the latest update to its Mac operating system, which includes over 70 critical security patches. These patches address a range of vulnerabilities, from kernel issues to the risk of unauthorised access to sensitive data in applications such as Siri, Maps, and Shortcuts. The update resolves potential exploits including arbitrary code execution, privilege escalation, and memory leaks. To further strengthen security, Apple has improved memory management, input validation, and sandboxing, providing enhanced protection against various types of attacks.
In addition to Sequoia, Apple has released security updates for older versions: macOS Sonoma (version 14.7) and macOS Ventura (version 13.7). Full security details for each version can be found by accessing the respective update links.
While Apple prioritises its newest macOS versions, it continues to offer vital security patches and bug fixes for older systems. This long-term support helps protect Macs that are unable to upgrade to the latest version, ensuring their continued security.
