You can directly install a Symantec Endpoint Protection client on a Mac computer if you cannot use or do not want to use Remote Push. The steps are similar whether the client is unmanaged or managed.
The only way to install a managed client is with a package that Symantec Endpoint Protection Manager creates. You can convert an unmanaged client to a managed client at any time by importing client-server communication settings into the Mac client.
If you downloaded the installation file or received a product disc
Perform one of the following tasks:
If you downloaded the installation file, extract the contents to a folder on a Mac computer, and then open the folder.
If you received a disc, insert it into a computer.
Copy Symantec Endpoint Protection.dmg to the desktop of the Mac computer.
Double-click Symantec Endpoint Protection.dmg to mount the file as a virtual disk. You then install the Symantec Endpoint Protection client for Mac.
If you have a client installation package .zip
If you exported the installation package or downloaded the client installer package from MySymantec, copy the file to the desktop of the Mac computer.
The file may be named Symantec Endpoint Protection.zip or Symantec_Endpoint_Protection_version_Mac_Client.zip, where version is the product version.
Right-click Open With > Archive Utility to extract the file's contents.
Open the resulting folder. You then install the Symantec Endpoint Protection client for Mac.
The resulting virtual disk image or folder contains the application installer and a folder called Additional Resources. Both items must be present in the same location for a successful installation. If you copy the installer to another location, you must also copy Additional Resources.
To install the Symantec Endpoint Protection client for Mac
To acknowledge the required restart, click Continue.
To review the license agreement, click View License Agreement.
To begin the installation, click Agree & Install.
Enter the user name and password for the Mac administrative account when prompted, and then click Install Helper.
(This step applies only to Symantec Endpoint Protection 14.0.1.)
To authorize the Symantec Endpoint Protection kernel extension for macOS 10.13, in the installer pane, click System Preferences, and then in the Security & Privacy system preference pane, click Allow. You do not need to enter a password.
In the installer pane, click Close & Restart to complete the installation.
When you log back on to the Mac computer, LiveUpdate launches to update the definitions. LiveUpdate runs silently in the background and does not display its progress onscreen.
If you were prompted to authorize the kernel extension but did not do it in step 5, do so after the computer restarts. You must authorize the kernel extension for Symantec Endpoint Protection to fully function.
