When attempting to install Symantec Endpoint Protection 12.1 to a Macintosh client, an error message is promptly displayed.  SEP 11.x was running without any issue on this Mac.


The error message reads:

"Symantec Endpoint Protection cannot be Installed on this computer.  This software requires Mac OS X 10.5 or newer on Intel architecture."


The computers in question have specifications such as:
Model Name: iMac G5
Model Identifier: PowerMac12,1
Processor Name: PowerPC G5 (3.0)
System Version: Mac OS X 10.5.8 (9L31a)   (PPC 32-bit)


SEP 12.1 introduces new features and functionality to SEP for Mac, but it also introduces new system requirements.  Supported Operating Systems and processors for SEP 12.1 are as follows:

  • Mac OS X 10.5 or 10.6 (32-bit, 64-bit)
  • Mac OS X Server 10.5 or 10.6 (32-bit, 64-bit)
  • 32-bit processor for Mac: Intel Core Solo, Intel Core Duo
  • 64-bit processor for Mac: Intel Core 2 Duo, Intel Quad-Core Xeon Processor



Symantec Technical Supports recommends that affected customers continue to use the latest available release of SEP 11.x on the older Mac clients in the environment. The SEP 12.1 SEPM has the ability to manage legacy SEP 11 clients as well as the new SEP 12.1 clients.

If the SEP 12.1 SEPM in the environment is a new deployment rather than an upgrade from the SEP 11.x SEPM, it will be necessary to drop a new sylink.xml file onto the SEP 11.x Mac clients.  This settings file will direct the legacy clients to the SEP 12.1 SEPM.  Instructions for performing this operation can be found in How to convert an unmanaged SEP for Macintosh client to managed

Customers who wish to see a future release of SEP 12.1 fully supported on PPC architecture may wish to express their support to the following Connect Forum enhancement request: Symantec Endpoint Protection 12.1 Support for PowerPC


Please note: it is recommended that these legacy clients always be kept up-to-date with the latest release of SEP 11.  Whenever there is a new Release Update (RU) of SEP 11, administrators are encouraged to import its Client Install Packages into the SEP 12.1 SEPM and deploy them to the legacy clients.  See How to Install Symantec Endpoint Protection v. 11.x from the Symantec Endpoint Protection Manager v.12.1? for details.
