The firm hasn’t stated which particular security concerns the current patches address, but it’s safe to assume that the changes make macOS a more secure operating system overall. In January, the Cupertino-based business issued WebKit security-related upgrades for both macOS Big Sur and macOS Catalina. These two security patches for all users were on the market shortly after the WebKit security-related updates.
