I was using Wake on Demand (not WOL) to access my mac remotely. I was able to turn in on from LAN or internet through SSH, VNC or HTTP. The problems came when I upgraded to Mountain Lion. Initially It was working for a small amount of time after the computer was set to sleep: after about half an hour it wouldn't turn on. Then, a few weeks later, as soon as it went to sleep there was no way to wake it up. I recently upgraded to Mavericks with the hope that it would have solved the problem but nothing has changed.
I tried all the possible solutions in this article but nothing helped me. In the last updates there are some workarounds but those are not what I want: they are simply keeping the mac on with the screen off, not sleeping. Is there anyone who managed to use the real wake on demand after Mountain Lion?
Update: Today, after the update 10.9.2, wake on demand suddenly started working again.
