Yesterday, like every Monday, we were expecting a new beta for iOS and MacOS.
But suddenly, Apple has surprised us with two updates, iOS 11.2.2 and, also, macOS High Sierra 10.13.2, for all users.
You can now find both updates at:
- iOS: Settings > General > Software update
- MacOS: Go to the App Store, the updates tab.
It is highly recommended, as Apple says,to update all devices.
What is the update to iOS 11.2.2 and macOS High Sierra 10.13.2?
Since mid-December various vulnerabilities have been known that could affect iOS devices.
To fight against all of them, the bitten apple releases such updates to mitigate discovered security issues.
This time, the update provides a security enhancement. So it is recommended that all users update their devices to iOS 11.2.2 and macOS High Sierra 10.13.2.
According to Apple, this update provides security improvements in the Safari app and Webkit to reduce the Specter vulnerability.
What is Spectre?
Meltdown and Spectre
Spectre is a vulnerability in INTEL and ARM processors.
This vulnerability affects iOS and MacOS devices, although to date there is no method that can compromise their systems.
This vulnerability has no effect at the software level, and may go unnoticed. But it can access special areas of memory, including the heart of the operating system.
Lack of verification, it seems that the update is dedicated to Safari . We are waiting for Apple to update their page and explain this update in detail.
It's important to see how Apple has gone to work to fix this. Although it will take time before the problem can be considered solved.
Which devices are compatible with the iOS 11.2.2 update and and MacOS High Sierra 10.13.2 update?
For the update to iOS 11.2.2 are supported:
- iPhones from iPhone 5S onwards.
- From iPad Air onwards.
- And iPod touch 6th generation.
MacOS update is a supplement for Safari, compatible with MacOS High Sierra 10.13.2 .
And you, have you updated yet? Remember that since it's a security patch, it's better to do it, lest we have to regret it later.
