Apple has launched a rapid security response update, aimed at implementing security fixes that the company recommends to all users. The new update is labeled iOS 16.5.1 (c). The company stated, "The rapid security response update provides security fixes, and it is advised that all users complete it." Apple did not specify what security issues the new update addresses. This update was released on Monday, but was quickly pulled after it was found to cause problems with the Safari browser, as it no longer supported sites like Facebook and Instagram.
