Apple has launched iOS 18.3, the third major update of the iOS 18 operating system, and although it does not include as many new functions as versions 18.1 and 18.2, it arrives with important changes in Apple Intelligence, visual improvements and corrections of security errors that deserve to be highlighted .

Update to iOS 18.3
The main change comes with Apple Intelligence, which now It is automatically activated When installing iOS 18.3, Ipados 18.3 or Macos Sequoia 15.3 in those compatible devices, such as the iPhone 15 Pro, iPhone 16 Pro, iPad Mini 7 and all the Macs and iPads with chips of the series M. If you had not activated this function before Now you will have to deactivate it manually from the adjustment app if you prefer not to use it. This change has generated some debate, since it makes Apple Intelligence a predetermined tool instead of optional. However, in Spain, we will not have it available until April.
Among the most striking novelties, Visual Intelligence expands its abilities in the iPhone 16, allowing now Identify plants and animals From the camera, in addition to adding events to the calendar automatically. These improvements reinforce Apple’s commitment to integrate intelligent tools into the daily experience of users.
Regarding notifications, Apple has made significant adjustments in the summaries generated by Apple Intelligence due to the controversy generated recently on the occasion of the false headlines to which they were giving rise. At the moment, notifications related to news and entertainment have been deactivated, and the company has added a warning in the adjustments, indicating that this function remains in the beta phase and could present errors. In addition, the possibility of managing notifications directly from the lock screen has been incorporated, giving the user more control.
New funds and safety problems solved
Another unexpected novelty and that has caused some enthusiasm is the return of a function in the calculator app which was withdrawn by Apple and has returned. Now it is possible to repeat the last mathematical operation by clicking twice the equal sign, a feature eliminated in iOS 18 that returns to facilitate calculations such as composite interest. For example, if it makes a multiplication x2, and we give it a =, perform the operation, and if we continue to click the De = button, the result will multiply again, and so on.
As if that were not enough, iOS 18.3 introduce a New Wallpaper which celebrates the Black Unity 2025 collection, accompanying the new belt design for the Apple Watch recently announced.
In the corrections section, Apple has solved several important problems. Among them, a failure that made the keyboard disappear when using the writing function to Siri, and an error in Apple Music that allowed music to continue playing even after closing the app. In addition, critical security vulnerabilities have been addressed, as a problem in Coremedia that allowed attackers to raise privileges, and a gap in the APP photos that exposed content even if the iPhone was blocked. In fact, Apple has published a document in which they comment that this new update solves More than 20 vulnerabilities. Errors related to AirPlay, Webkit and the Kernel of the system that could have been used by malicious applications have also been paired.
