Apple released its fifth maintenance update to the macOS High Sierra 10.13 operating system series, version 10.13.5.
The update brings in additional security, along with the usual bug fixes.
Coming just over a month after the April 24 release of macOS High Sierra 10.13.4, the new OS update continues to improve the security, compatibility, and stability of Mac computers.
One of the highlights of the update is the implementation of the Messages in iCloud feature that Apple also added in the iOS 11.4 release to allow users to store their iMessages on their iCloud accounts for easy sync between their iPhone, iPad and Mac devices.
Vulnerability fixes cross several components like Accessibility Framework, AMD, ATS, Bluetooth, Firmware, FontParser, Grand Central Dispatch, Graphics Drivers, Hypervisor, iBooks, Intel Graphics Driver, and others.
macOS High Sierra 10.13.5 can be installed on MacBook Late 2009 or newer, MacBook Air Late 2010 or newer, MacBook Pro Mid 2010 or newer, Mac mini Mid 2010 or newer, iMac Late 2010 or newer, iMac Pro 2017, and Mac Pro Mid 2010 or newer computers running a release of the macOS High Sierra 10.13 operating system.
macOS High Sierra 10.13.4 introduced a new 64-bit testing mode for application developers to test their software for 64-bit compatibility as Apple will soon deprecate 32-bit support on future releases of macOS, most probably starting with the next major version, macOS 10.14, which Apple may unveil next month during WWDC 2018.
For end users, macOS High Sierra 10.13.5 is another security and stability update that improves the reliability of macOS.
