Apple software update 4.3.1 fixes a bug that prevents the lock screen from showing when a device is connected to a Wi-Fi network, and fixes an issue that could cause a lock screen to appear as blank when the device is locked.
Apple’s latest Software Update for iOS and OS X brings a number of security fixes, as well as a new “lock screen” feature that automatically unlocks your device if it’s connected to Wi-fi.
The update comes with the following changes: It fixes a memory leak that could allow an attacker to execute arbitrary code in the context of a background process.
It updates the app icons to match the new lockscreen design.
If you’re using iOS 10, you’ll see a new icon in the top right corner of your lock screen.
If you’re running OS X 10.10 Yosemite or 10.11 El Capitan, the new icons will be in the corner.
The update comes in a single, 32-bit, 64-bit installer for OS X and iOS.
In addition, Apple has updated the app icon, the notification bar, and the menu bar.
The latter three have been updated as well.
