====== Missing events from macOS builds ======

On some versions of Unreal Engine 5, the default [[https://developer.apple.com/documentation/bundleresources/entitlements|entitlements]] used by Unreal Engine for some build types of [[https://developer.apple.com/documentation/security/app_sandbox|sandboxed apps]] are missing the required support for network communication (entitlement [[https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_network_client|com.apple.security.network.client]]). This makes the operating system to discard all the messages sent by the plugin. The solution is to simply add the required missing entitlement.

===== Project settings =====

Options for the used entitlements can be found under //Project Settings > Platforms > Xcode Projects//, section //Entitlements//:

  * //Mac: Development Entitlements//, set to ''/Game/Build/Mac/Resources/Sandbox.Server.entitlements''
  * //Mac: Shipping Entitlements//, set to ''/Game/Build/Mac/Resources/Sandbox.NoNet.entitlements''

You must ensure the used //entitlements// files contain the following snippet:

<code xml>
<key>com.apple.security.network.client</key>
<true/>
</code>

===== Working entitlement file =====

For example, this is a minimal change of file ''Build/Mac/Resources/Sandbox.NoNet.entitlements'' for UE5.3.2 that makes the communication working:

<code xml>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.security.app-sandbox</key>
    <true/>
    <key>com.apple.security.network.client</key>
    <true/>
</dict>
</plist>
