I am using this parallel to a PC running "Jimmy's Magic Packet" (a free, extremely lightweight program for Windows)The only number that Jimmy's Magic Packet needs is the MAC address (or Physical Address) of the computer you're trying to wake. Then it works.This program need 3 more fairly obscure numbers (IP Address or FQN, Subnet Mask, and Port) in order to send a packet. The only way I was able to get all that information was to manually power on the PC that I wanted to wake, then use the "discover" function of the app, then search through a long list of computers by MAC address to find the one I was looking for. I am the network admin at a company so it would be really helpful to only need the MAC address instead of trying to sort through a long list of computers by MAC address. Also, although it does add computers to a sort of 'bookmarks' list, I cannot remove these items from a list. So if you incorrectly put in some numbers and send a packet that fails, that attempt will be in your list forever. The 'help' section was pretty unhelpful. All the suggested/default values were wrong.

App works great if the computers are on your network, however this app does not allow you to connect to a computer "anywhere" in the world via the internet. You can not manually enter a computer's Mac and IP address, the only way to try and connect is via getting the computer discovered. Well to be discovered it must be on your network! This makes it very difficult to "discover" a computer outside of your current IP address. Next, even if you can finagle the software to manually enter the IP address, it will crash every time you push the wake button.

Does not work. Will not wake up the other Mac on the network (will only discover it if it’s not sleeping; preferences are set to Wake). Not so well documented. Developers haven’t updated their own site lately, so am not expecting much.One big flaw: you can’t name the bookmarks! So you have to remember the IP address or the MAC address on your own? Seems to defeat the purpose of the app in the first place, as being one of convenience.

I just woke my PC up with my 2011 MBP. $1.99 saves me from having to stand up, step 2 feet away, and press the power button. God bless America. If it doesn't work for you, your router might be misconfigured, or maybe you mis-typed your Mac address. Apparently you can only wake up other Macs if they are sleeping, and not turned off. That's an issue with OS X.
