If you haven’t already, you need to install the latest software update for your iPhone, iPad or Mac immediately.
Earlier this week, Apple pushed out an important security update for its macOS and iOS operating systems.
The updates protect Apple devices against the Spectre and Meltdown security vulnerabilities which were recently found to affect nearly all processors made over the last 10 years.
The Spectre flaw affects devices running AMD and ARM chipsets, while Meltdown affects Intel processors and could be exploited by hackers to access sensitive data such as passwords and other online login credentials.
Both vulnerabilities could potentially allow hackers to bypass protection in the device kernel, which has complete control over the whole system of the device and is used to connect applications and software to the processor, memory and other hardware.
Apple has said that it is unaware if hackers have been able to exploit the flaw but did confirm that all of its devices, with the exception of the Apple Watch are affected.
“All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time,” Apple said in a statement earlier this month.
“These issues apply to all modern processors and affect nearly all computing devices and operating systems.”
In a post on its website the Cupertino firm advised anyone with an iPhone 5S or newer, iPad Air or newer or iPod Touch to download iOS 11.2.2 immediately.
You can do this by going to Settings > General > Software Update.
For anyone running macOS you need to install High Sierra 10.13.2.
