The corporate is upfront—virtually in your face—that Lockdown mode is an possibility that may degrade the consumer expertise and is meant for less than a small variety of customers.
“Lockdown Mode presents an excessive, optionally available stage of safety for the only a few customers who, due to who they’re or what they do, could also be personally focused by among the most refined digital threats, resembling these from NSO Group and different personal corporations creating state-sponsored mercenary adware,” the corporate mentioned. “Turning on Lockdown Mode in iOS 16, iPadOS 16, and macOS Ventura additional hardens machine defenses and strictly limits sure functionalities, sharply decreasing the assault floor that doubtlessly might be exploited by extremely focused mercenary adware.”

One factor everybody ought to learn about Lockdown mode, at the very least as described on Wednesday by Apple, is that it doesn’t cease your machine from connecting to mobile networks and broadcasting distinctive identifiers like IMEI and ICCID. That’s not a criticism, only a pure limitation. And trade-offs are a core a part of safety.
So for those who’re like most individuals, you’re by no means going to wish Lockdown mode. However it’s nice that Apple can be providing it as a result of it’s going to make all of us safer.
