The macOS 10.14.5 update is now available. You can also get the compatible refresh build for the Mac client for version 14.2 RU1, 14.2.3335.1000 in the following ways, from MySymantec, under My Products > Endpoint Protection:
Download the All Clients file, which includes the Mac client installation package.
Download the Full Installation file, navigate to \SEP_Mac\, and then download Symantec Endpoint Protection.dmg for installation on the Mac client computer.
Download the Full Installation file, which includes the package to upgrade Symantec Endpoint Protection Manager. After you upgrade Symantec Endpoint Protection Manager, you can upgrade managed clients automatically. See: Upgrading client software with AutoUpgrade
The refresh build applies to on-premises clients managed through Symantec Endpoint Protection Manager and to cloud clients managed by Symantec Endpoint Protection 15.
If you upgrade to macOS 10.14.5 before you install the refresh build, the functionality of antivirus, firewall, and intrusion prevention technologies may be affected. You may experience one or more of the following issues:
Symantec Endpoint Protection kexts may fail to load.
Symantec Endpoint Protection kexts may load and work, but the following warning message displays:
System Extension Warning One or more system extensions that you have approved will be incompatible with a future version of macOS. Please contact “Symantec” for support.
You should therefore delay the operating system upgrade to macOS 10.14.5 until you can update Symantec Endpoint Protection to the 14.2 RU1 refresh build.
