This can be frustrating if the volume controls on your external display are concealed in the bezel or buried in a fiddly on-screen menu. That's because HDMI, DisplayPort, and Thunderbolt connections carry a fixed volume digital audio signal, so the external device (in this case, a monitor) controls the sound level. ![]() Sometimes older OSes aren't affected by all the same vulnerabilities as newer ones, but this is also information Apple doesn't usually provide.If you connect your Mac to an external display, you may find that the Mac's on-screen and keyboard volume controls are disabled. Sometimes older versions get the same patches later, and sometimes they don't get patches at all, even if they are being actively updated.Ĭase in point: the iOS 15.8 release lists a single kernel-level security problem, CVE-2023-32434, while the iOS 16.7.2 update fixes 17 vulnerabilities throughout the operating system, and iOS 17.1 fixes 21. Regardless, Apple has said in the past that only its latest operating systems are guaranteed to be fully patched. But it will gradually become less safe to use them on the Internet, and new app updates and websites will gradually leave them behind. If you hang on to hardware for a long time, or if you hand devices down to kids or other family members for extended use, it's worth keeping track of what operating systems Apple is still actively supporting.ĭevices that stop getting security updates will continue to function, and app developers can choose to target older iOS versions for as long as they want. But with Apple's sales volumes, that still leaves millions of devices that can benefit from continued iOS 15 security updates. Of those, a fair number are newer devices that can be updated to versions 16 and/or 17.
