Earlier this week was publishedversion 12.4 of macOS Monterey, with its share of new features including the first stable version of Universal Control or even an improvement of the camera on Studio Display. With this, around fiftysecurity vulnerabilitiesconcerning the proprietary Safari browser have been corrected by Apple.
Unfortunately,some deviceslike the2012 iMacor 2015 MacBooks do not have the right to this operating system. For them, you will have to make do with previous editions. However, it turns out that other gaps that are also particularly risky have not been filled for a while. It is now done.
For Catalina
On macOS Catalina, the numbered security update2022-004has been available since Monday. It corrects several problems encountered by Apache 2.4.53, as well as others potentially giving control of the computer to hackers. Added to this are also patches for AppKit, AppleScript, DriverKit and the drivers from the Intel founder equipping devices released before the arrival of in-house ARM chips.
For the occasion, Apple thought of thanking someresearchershaving discovered these dangers. Among them, we find in particular Michael DePlante of the Trend Micro Zero Day Initiative or Yonghwi Jin of Theori.
For macOS Big Sur
At the same time, Apple also deployedmacOS Big Sur 11.6.6which puts an end to many of the same flaws, also on the side of Wi-Fi, WebKit, software updates and printing settings.
Installation procedure
As is often the case, you are strongly advised to install one or other of these updates if you do not wish to or cannot switch to Monterey. This will prevent you from possible theft of personal data or any other mishap of the same ilk.
To do this, the procedure has not changed: you must go to the Apple menu, then touchAbout this MacetSoftware update. Please note that the operation may take some time which will depend on the speed of your connection; therefore plan another machine for a good hour to avoid any delay if it is professional equipment.
