In Fusion for Mac 8.5, sometimes i get the popup to "allow" or "deny" access to vmware-natd, which i' also positive is networking..
however, i know that the Firewall is related to Apple, but in Sierra, there is a new option in Firewall tab "Automatically allow built in software to receive incoming network connections"
macOS Sierra: Firewall pane of Security & Privacy System Preferences
Mine is ticked, so why am i being asked to allow this it this is supposed to automatically allow?
In addition, the only reason why i bring this up, is prior to 8.5 Fusion, I never saw this popup ever...... so Apple must of made some changes... nether the less in 8,5, i just ignored the popup, and everything still works as normal...
If no one knows why i am being asked this in Serria, then i'll just continue ignoring it, as Fusion seems to work fine without any action taken.
