This is the second time in recent days I've seen that expression used
in conjunction with FD, Mac, and top. Perhaps you were on IRC.
OSX on MBP is, by default, very aggressive with power management. OSX
always shuts down network PHYs when in "full sleep" state. Apple has a
proprietary power state named "Power Nap" that allows remains awake
enough to maintain a wifi connection.
System Preferences -> Energy Saver
In Energy Saver,on Power Adapter tab, slide "Computer sleep" slider to
the right all the way to "Never"
Check "Put hard disks to sleep..."
Check "Wake for network access..."
Check "Enable Power Nap..."
Note that it isn't enough to check "Enable Power Nap". The "Computer
sleep" slider must be slid to "Never". Also note that this is not
possible when on battery.
Now the bad news. A MBP is not designed to run with the lid closed.
Closing the lid interferes with proper heat dissipation should the CPU
be running at full speed, so the MBP automatically goes to full sleep
when the lid is closed. Supposedly, enabling "internet connection
sharing" prevents this, though I have not tested it.
System Preferences -> Sharing
Check the "Internet sharing" box on the left
Select the interface to share on the right.
These Macs have been very frustrating to use with Bacula, mostly due to
the aggressive power management. And now we will have to deal with the
same thing with Windows 10, most likely. I really believe that Bacula is
going to have to stop relying so heavily on the longevity of a TCP
connection. Particularly for wireless networks, device makers are
increasingly choosing to ignore TCP/IP standards in favor of power
conservation.
