Apple Intelligence Reactivation Issue Post iOS 18.3.1 and macOS 15.3.1 Update

Users report Apple Intelligence being re-enabled after updating to iOS 18.3.1 or macOS 15.3.1, despite previous deactivation.

So, you’ve updated to iOS 18.3.1 or macOS 15.3.1, thinking you’re all set, only to find out Apple Intelligence has decided to throw a surprise party on your device—uninvited. Developer Jeff Johnson spilled the beans in a blog post, sharing how the updates played favorites with his gadgets, turning features back on without so much as a ‘by your leave.’

Here’s the kicker: that ‘Welcome’ screen after updating? It’s been playing fast and loose with your settings, flipping Apple Intelligence back on like it owns the place. Suddenly, Notification summaries are summarizing, Mail is categorizing like there’s no tomorrow, and Siri’s getting chummy with ChatGPT—all without your say-so.

Good news? It’s a quick fix. Just hop into Settings > Apple Intelligence & Siri and show it who’s boss by toggling it off. But let’s be honest, it’s a hassle nobody signed up for, especially if you’re not into AI calling the shots on your device. Apple’s likely already on it, though, so future updates should play nicer with your preferences.

And hey, Apple Intelligence isn’t sitting still. Rumor has it, iOS 18.4’s packing even more AI tricks. Maybe this little hiccup is the universe’s way of nudging you to give it another look. Or not. Your call, really.
