I have a Macbook Pro from late 2011 with an SSD drive (that came from apple). It had Lion till a few days ago. The energy saver was set to 10 minutes for both screen and machine sleep. Back then, if I start downloads, run MacTheRipper, etc, and let it be, the screen eventually goes dark, and if I hit any button, I get the login prompt, I log in, and see that the downloads are still going on, and MacTheRipper is still ripping, and I even see that some emails have appeared, etc. This all changed when I upgraded to mountain lion. Now, the mac goes to sleep and when I come back and hit any key to wake it, I log in and find that my downloads have been "paused" and mactheripper too. MacTheRipper picks up where it left, of course. But the downloads have to be restarted. I looked on the net, and I found this new feature: PowerNap. Except that my mac is not the Retina one and so it is incompatible with that. But as I describe above, it used to behave just like they describe in PowerNap!!!! Can I get that behavior back??? Has anybody experienced this as well??? What did you do? Just live with it??? I hoping there's a way to have that behavior back. I don't want to set the machine sleep time to "Never" and then back to 10 minutes, and so on and so forth!! Help!!
