Apple has finally introduced iPhone Mirroring, the feature that lets you mirror and control your iPhone from your Mac. iPhone Mirroring is great, and it’s one of the headline features in iOS 18 and macOS 10.15 Sequoia. But it also comes with security concerns that need to be considered.

Since there's always a chance that your iPhone was mirrored to someone else's Mac, your iPhone will show a notification that it was used from a Mac.
iPhone can only be mirrored when it is locked. So when you are using your iPhone, you can be sure that it is not mirrored anywhere. But what about when it is locked?
This is where the “iPhone has been used from Mac” message comes in. Not only does it let you know if someone else is mirroring your iPhone, it’s also useful if your mirroring connection drops. If you’ve been mirroring your iPhone and you see that message, you can rest assured that the connection is now broken.
