During the past few weeks, I've noticed that when my 2013 Mac Pro sleeps, all of the peripherals go into a lower power mode (speakers mute themselves and then eventually go into standby, usb hub lights shut off) and it doesn't appear that the network stays active. For instance, if I send a bunch of messages to someone while the Mac is asleep, when I come back and wake it up, all of the messages quickly catch up.
Does your Mac Pro behave the same way during sleep?
