Hotfix
1264214
Issue: [Installation] The Product Improvement Program (PIP) (Telemetry) can be unexpectedly enabled in the Server Settings page after you upgrade the McAfee Agent extension to version 5.6.0.207.

1263865
KB91185 5.6.0 n/a Issue: Reports that cover Managed Mac operating systems disappear after you upgrade to McAfee Agent 5.6.0 or later. McAfee Agent 5.6.0 and later report the Mac operating system as either 'macOS' or 'MAC OS X'.

Resolution: A design change occurred in McAfee Agent 5.6.0 regarding the reporting of the Mac operating system. 
  • McAfee Agent 5.5.x reported the OS Type value only as Mac OS X.
  • McAfee Agent 5.6.0 and later report the Mac OS Type as macOS or MAC OS X. See the related article for details.
Update your reports and set the OS Type value to macOS.
1238363 - 5.6.0 - Issue: McAfee Agent settings display incorrect values when policies are compared using Policy comparison.
1262433 - 5.6.0 -
Issue: After you uninstall the McAfee Agent with uninstall.sh on a Linux operating system that also has Endpoint Security for Linux installed, the following misleading message is displayed on the console: Agent got uninstalled.
You can safely ignore this message. The McAfee Agent is not uninstalled because of the dependency by Endpoint Security for Linux. A future update addresses this cosmetic issue.
1262432 - 5.6.0 - Issue: The Incompatibility Check policy located under McAfee Agent, General, is disabled when policies are imported with the policy import option.
1220515 - 5.5.0 - Issue: The McAfee Agent Smart Installer does not support configuration of a RelayServer through the command line.
1155972 - 5.0.5 - Issue: When the McAfee Agent mode is changed from 'managed' to 'self-managed' on Windows operating systems, EpoServerLastUsed and LastASCTime registry keys still contain managed information.
1168133 - 5.0.2 - Issue: If the system time is changed while a task is in progress, the task is immediately freed up.
1174728 - 5.0.4 - Issue: Tasks are scheduled beyond the "until" time if:
  • The task is set to "repeat until" a specific date and time.
  • Daylight Saving Time (DST) shifts the clock one hour ahead of the actual time.
1077826 KB85224 5.0.2 - Issue: An upgrade of McAfee Agent to version 5.0.x fails if the Prevent Programs Registering as a Service rule is blocked in the Access protection policy of VirusScan Enterprise.

Workaround: Disable the Prevent Programs Registering as a Service rule in the Access Protection policy for VirusScan Enterprise, and then retry the upgrade.
1067653 - 5.0.1 - Issue: A duplicate node entry is created for a Linux system if you upgrade from McAfee Agent 5.x.x to McAfee Agent 5.x.x with McAfee Smart Installer.

Workaround: If you notice duplicate entries, schedule a server task to identify duplicate entries and delete the inactive node. See the ePolicy Orchestrator Product Guide for instructions on how to schedule a server task.
1040305 - 5.0.1 - Issue: Agent deployment tasks download the FrameworkConfig.zip and FrameworkInstall.zip files even though they are not used by agent deployment tasks.
1031325 - 5.0.1 - Issue: The next runtime of a task is not recalculated when you change the randomization interval value for a local task.
1029656 - 5.0.1 - Issue: A missed task does not execute if the task is scheduled to run repeatedly.
1024771 - 5.0.1 - Issue: Messages in Agent Monitor are not logged sequentially.
982072 - 5.0.1 - Issue: Customized policies are not enforced on clients while McAfee Agent is switched between modes (managed or unmanaged).

KB86939 5.0.0   Issue: On non-Windows systems, McAfee Agent 5.x is unable to listen for wake-up calls on ports lower than 1024.
Workaround: See the related article for details.
990577 KB82895 5.0.0 - Issue: Managed tasks do not appear in the VirusScan Enterprise console after you install McAfee Agent 5.0.x.
Workaround: Restart the VirusScan Enterprise Task Manager (VsTskMgr.exe) when you create new managed tasks. See the related article for details.
989633 KB77630 5.0.0 - Issue: Incorrect system properties for operating system Build Number, Total disk space, Used disk space, and Free System Drive Space are displayed in ePO for non-Windows systems.
934776 - 5.0.0 - Issue: When you compare client tasks in ePO, the output displays string IDs instead of the actual strings.
1135834 - 5.0.0 - Issue: Policy changes are not applied as designed until the user logs on again or reboots the system for the Security Innovation Alliance partner product Avecto DefendPoint. This fact affects Microsoft Active Directory domain user accounts, but does not affect Windows local user accounts, for which policy updates still occur live.
1060850 - 5.0.1 n/a Issue: McAfee Agent fails to schedule the on-demand scan task post upgrade when VirusScan Enterprise is present.

Resolution: After you restart the system, McAfee Agent schedules the task successfully.
1070435 KB84917 5.0.1 n/a
Issue: The following error occurs while you uninstall McAfee Agent with the Frminst.exe /forceuninstall command:
 
"This action is only valid for products that are currently installed"
 
Resolution: Run the Microsoft MSIZAP (msizap.exe) tool to remove the remnants of McAfee Agent 4.x.x. See the related article for details.
1131469 - 5.0.3 n/a Issue: If you change the system time multiple times, the next agent-server communication interval (ASCI) time value is printed incorrectly in the McAfee Agent Status Monitor. This incorrect value has no impact on the ASCI.

Resolution: On the next scheduled ASCI, the time value is corrected automatically.
- KB87110 5.0.2 Hotfix 1110392 and 5.0.3 and later n/a Issue: After you perform the following installation sequence, the system is vulnerable to the trusted access bypass vulnerability described in SB10151 after you upgrade McAfee Agent:
  1. Install McAfee Agent 4.8.x and Host Intrusion Prevention 8.x or Data Loss Prevention Endpoint 9.x (or both) on the client.
  2. Upgrade McAfee Agent to 5.0.2 Hotfix 1110392 or 5.0.3 and later.
Resolution: Restart the system after you upgrade McAfee Agent to completely mitigate the trusted access bypass vulnerability in this scenario.
1109811 - 5.0.2 Hotfix 1110392 and 5.0.3 and later n/a Issue: McAfee Agent 5.0.2 Hotfix 1110392 and later, which uses SysCore 15.4.0.773 and later, fails to install on Windows 7 operating systems.

Resolution: Install the Microsoft fix documented in https://support.microsoft.com/en-us/kb/2328240 before the McAfee Agent installation.
1175956 KB88972 5.0.5 n/a Issue: VirusScan Enterprise 8.8.0 Patch 4 and earlier does not whitelist McAfee Agent executables. Access Protection hits are generated for masvc.exe if VirusScan Enterprise 8.8.0 Patch 4 and earlier versions are installed.

Resolution: Restart the client after you install VirusScan Enterprise 8.8 Patch 4 or earlier.
1181853 - 5.0.4 n/a Issue: The macOS computer hangs and McAfee Agent does not respond for about five minutes when the following conditions occur in the listed order:
  1. You enable Endpoint Security for Mac (ENSM) Threat Prevention On-Access Scan (OAS).
  2. You upgrade to macOS to version 10.12.3.
  3. You upgrade McAfee Agent.
Resolution: The McAfee Agent process, Macompatsvc, takes some time to start if ENSM Threat Prevention OAS is enabled. Wait for the McAfee Agent process to start after the operating system upgrade, and then perform the McAfee Agent upgrade.
965063 KB82896 5.0.0 n/a
Issue: The McAfee Agent 4.x logging policy does not migrate to the 5.x remote logging policy.

Resolution: Update any existing McAfee Agent Logging policies to the new settings. For more details about the new settings, see PD25187.
953245 KB83195 5.0.0 n/a Issue: A Program Compatibility Assistant pop-up window displays when you close SmartInstaller.exe installation windows for McAfee Agent 5.x on Windows 7.

Workaround: You can safely ignore the pop-up window and select "The program installed correctly" to close the window. See the related article for details.
- - 5.0.0 n/a Issue: The agent monitor displays an 'Agent service is now stopped' status.

Cause: A restart initiated by group policy is applied to clients with McAfee Agent 4.x.x. This restart changes the McAfee Agent Backwards Compatibility Service state from manual to automatic.

This issue also occurs on a fresh installation of McAfee Agent 5.x when there is a Group Policy set to enable McAfee services, or any other third-party application that do the same.

Workaround: Disable this group-level policy on systems that run McAfee Agent 5.0.0 and later because McAfee Agent now has an automatic recovery mechanism when stopped unexpectedly.
- KB85870 5.0.0 n/a Issue: McAfee Agent or ePO installation fails with the following error when KB3072630 is installed:
 
Error 1911.Could not register type library for file C:\Program Files (x86)\McAfee\Common Framework\ComponentUserInterface.dll
 
Resolution: Verify that Microsoft Windows updates KB3072630 and KB3139923 are both present and installed on the impacted system. See the related article for details.
- KB83123 5.0.0 n/a Issue: A compatibility issue exists with third-party "hooking" applications when SysCore 15.3 is installed.

Resolution: See the related article for details.
Expected Behavior
1253297 - 5.6.0 Expected
Behavior
Issue: An uninstall of McAfee Agent on a Linux operating system using rpm -e MFEcma only uninstalls McAfee Agent and not Data Exchange Layer (DXL) 5.0.0.

Resolution: See the McAfee Agent 5.6.x Installation Guide for the correct usage of uninstall commands.
- KB90077 5.5.0 Expected
Behavior
Issue: McAfee Agent update policies appear incorrectly after you upgrade the McAfee Agent extension from 5.0.x to 5.5.0, or when policies are imported.

Resolution: This issue relates to web browser caching. See the related article for details.
1044276 KB85762 5.0.1 Expected
Behavior
Issue: The McAfee Agent Backwards Compatibility Service is not protected by VirusScan Enterprise if the agent's self-protection policy is disabled.

Resolution: To protect McAfee Agent Backwards Compatibility Service, always enable the self-protection policy for McAfee Agent.
1035603 - 5.0.1 Expected
Behavior
Issue: Intermittently, McAfee Agent on Mac OS X fails to collect and send properties to the McAfee ePO server.

Resolution: On the next agent wake-up call, McAfee Agent will collect and send the latest properties to the McAfee ePO server.
972679 KB82897 5.0.0 Expected
Behavior
Issue: McAfee Agent 4.5 upgrades to 5.x are not supported.
Resolution: You must remove all McAfee Agent installations earlier than McAfee Agent 4.6 or upgrade to McAfee Agent 4.6 Update 3 before you upgrade to McAfee Agent 5.x. See the related article for details.
n/a - not applicable. Resolution did not require an McAfee Agent-specific solution.
