ENSM Version
Resolved ENSM Version Issue Description
    10.5.7 As Designed Issue: After upgrading to ENSM 10.5.7, the file format of quarantined items changes to ZIP. As a result, if ENSM is reverted to a version earlier than 10.5.7, the restore from quarantine feature do not work for files in the new format.

Resolution: This behavior is as designed. To restore quarantined items, manually extract the quarantined items using the "Archive Utility" application on the Mac system.
1259847   10.5.6 DLP Endpoint 11.1.0 Hotfix 3 Issue: On a Mac system running ENSM 10.5.6 or later, installing Data Loss Prevention Endpoint (DLP Endpoint) downgrades certain common components used by ENSM.

Workaround: Install DLP Endpoint before installing ENSM.

Resolution: This issue is resolved in DLP Endpoint 11.1.0 Hotfix 3.
1254777   10.5.5   Issue: Quarantined files that have unicode characters in their name do not display on the Quarantine screen.
1250488   10.5.5 As Designed Issue: The ENSM console displays the following error message, when ENSM 10.5.5 Threat Prevention is uninstalled, and Management of Native Encryption and Data Loss Prevention are left on the system:
Your MAC is at Risk

Resolution: This behavior is as designed. Upgrade the 32-bit managed products to their 64-bit variants. ENSM 10.5.5 Threat Prevention must not be uninstalled before uninstalling other 32-bit managed products from the system.
1248901   10.5.5 As Designed Issue: ENSM 10.5.0 Threat Prevention on-access scan detection stops working after upgrading any other ENSM module, such as Firewall or Web Control, from 10.5.0 to 10.5.5.

Resolution: This behavior is as designed. When you upgrade to ENSM 10.5.5 from a previous version of the product, upgrade all modules of ENSM on the system.
  KB90267 10.2.3 10.5.0 Hotfix 1244068
10.2.3 Hotfix 1238954
Issue: Users see emails stuck in their outbox or slowness when sending emails using Apple Mail. This issue is experienced when ENSM Threat Prevention 10.2.3 or 10.5.0 is installed on macOS High Sierra running on an APFS partition. This issue does not occur when On-Access Scan is turned off.

Resolution: This issue is resolved in ENSM Threat Prevention 10.2.3 Hotfix 1238954 and ENSM Threat Prevention 10.5.0 Hotfix 1244068. See the related article for more information.
  KB90520 10.2.3 10.5.5 Issue: ENSM runs as a 32-bit application. When starting "McAfee Endpoint Security for Mac.app" for the first time on macOS High Sierra 10.13.4 and later, you see the following alert notifying you that the ENSM application is not optimized for Mac.

"McAfee Endpoint Security for Mac" is not optimized for your Mac.

    10.2.3 As Designed Issue: ENSM Threat Prevention 10.2.2 cannot co-exist with the ENSM 10.2.3 Firewall and Web Control modules.

Resolution: This behavior is as designed. When you upgrade to ENSM 10.2.3 from a previous version of the product, upgrade all modules of ENSM on the system.
1181639   10.2.1 10.2.2 Issue: ProductConfig.xml gets corrupted when ENSM blades are installed on an existing installation of Data Loss Prevention, File and Removable Media Protection, Management of Native Encryption, or McAfee Client Proxy.

Resolution: This issue is resolved in ENSM 10.2.2.

Workaround: After upgrading the operating system to Mac OS X Sierra 10.12, restart the Mac system.
1144747   10.1.0 10.2.0 Issue: Installing ENSM 10.1 after Data Loss Prevention (DLP) Endpoint for Mac 10.0 has been installed, causes both ENSM and DLP Endpoint for Mac to stop working.

Workaround: To run both applications, install ENSM 10.1 first, and then DLP Endpoint for Mac 10.0.

Resolution: This issue is resolved in ENSM 10.2.0.
1077269   10.0.0 10.2.2 Issue: Incorrect self-protection violation events are generated for Threat Prevention and Web Control locations after product deployment.

Workaround: If the processes that are stopped during deployment are Mkdir, CP, or WebKitPluginHost, you can safely ignore the events. The event ID is 1092.

Resolution: This issue is resolved in ENSM 10.2.2.
