There's a new feature in Apple's iOS 16 that you probably haven't heard of yet, but it will make a huge difference to your security.
The Real Reasons Apple Won't Put macOS on the iPad
It’s called Rapid Security Response (RSR), and it allows Apple to quickly patch security holes. Unlike regular iOS software and security updates, RSRs don’t require a reboot after installation, further lowering the barrier to entry for getting you as secure as possible, as quickly as possible. But it’s not all good. RSRs are relatively untested in the wild, and aren’t as secure as when they’re baked into operating system updates. And they’re also removable.
"The big danger is that these patches are built and distributed quickly, and therefore not tested as thoroughly," Dr. Howard Oakley, a Mac expert, told Lifewire via email. "They can therefore cause more compatibility issues, hence the importance of users being able to remove them if they wish."
When Apple discovers a vulnerability in iOS or macOS, they have to release a full OS update to patch it, which is annoying for the user. First, they might not update at all. Then, even if they have automatic updates enabled in the settings, it can take several days, and sometimes longer, for the updates to arrive.
