Supported client operating systems

The following table contains the workstation and server operating systems supported for MAR clients.
Only the most current versions are included because most customers upgrade to the latest service packs shortly after they are released. The Trace module is available on Microsoft Windows and macOS (Beta release) systems only.
 

NOTE: Non-English operating system support was introduced in MAR version 1.1.0.

¹ RTS = Release to Support.

IMPORTANT: If you install MAR 2.2.0 or later in a multiple ePO server environment, you must upgrade all your DXL components to 4.0. If you are operating in a single-server environment, you only need to update the extensions to 4.0. The reason is because DXL 3.x.x clients are compatible with those versions of MAR, but only in a single ePO server environment.  

In a single ePO server environment, you only need to upgrade the DXL extensions to DXL 4.0, while the DXL endpoint clients can remain on DXL 3.x. But, if you have multiple ePO servers deployed, MAR 2.2.0 and later requires that all DXL components are upgraded to DXL 4.0 version.

Use the following table to determine your minimum DXL components based on your ePO environment:

Single McAfee ePO server Environment			Multi-EPO Server
DXL ePO extensions	DXL Endpoint Client	DXL Broker	DXL ePO extensions	DXL Endpoint Client	DXL Broker
4.0.x	3.1.x	3.1.x	4.0.x	4.0.x	4.0.x

NOTE: If you stay on the 3.1.x broker, the Health Status page alerts you have an out-of-date broker. This alert can be disregarded.

Virtual infrastructure software versions

MAR client:
MAR client supports any virtualization solution, assuming the following criteria are met:

• MAR client and required dependencies (DXL, MA, Endpoint Security) support the operating system being virtualized.
• The virtualization solution is a supported solution from the virtualization solution vendor. So, the solution isn’t EOL, beta, or an otherwise unsupported virtualization solution.
• The virtualization solution supports the operating system being virtualized. To confirm operating system support, see the virtualization solution documentation.
• The virtualization solution runs under full virtualization or paravirt mode, if supported.
