Wake on Lan for a Mac Mini running Leopard not working

Not sure where to best post this, but here goes. I'm trying to set up a Mini as a music server for my audio system. The Mini is a core 2 duo with 1GB RAM from 2009 I think. I can upgrade it to Snow Leopard (possibly Lion/10.7 if I upgrade memory, which I may do anyway). The mini is on a LAN using a Netgear router and is only connected via wifi. No ethernet. The Mini is connected to a DAC by USB, and that is connected to the audio system.

I want to run this without a monitor or keyboard, and rely on my iPhone or MBAir to control the Mini via screen sharing. I want to let the Mini sleep when not needed, then wake when I want it for music. Trouble is, I can't get the Mini to wake up. I've tried Wake on Lan and other tools to wake it up remotely so I can then start playing music, but I can't get it to wake up.

I have the correct MAC address and IP address (I've reserved a local IP address for it). I'm sure both machines are on the same network. I've set the Mini to wake on lan in energy saver prefs.

Any suggestions? Thanks in advance!

You do not have to have a Bonjour Sleep Proxy to wake a sleeping Mac. A Bonjour Sleep Proxy just makes it easier for the client to wake the Mac as all the client has to do is try to access one of the services being proxied, and the Bonjour Sleep Proxy will send the necessary Wake-on-LAN packets to the sleeping Mac. And if the Bonjour Sleep Proxy is your home router, then the request can come from the internet, such as Back-to-My-Mac connection requests.

I think an Apple TV will also provide a Bonjour Sleep Proxy service.

But you DO NOT need to use a Bonjour Sleep Proxy. If you are on the same LAN as the Mac mini, you can use apps such as WakeOnLan for the Mac

Which will list ALL the available devices on the home LAN, such that you do NOT need to know the MAC address.

And there are a bunch of "Wake on LAN" apps for the iPhone, many I'm sure do not need to know the MAC address either.

Hey BDAqua, that's the wifi adapter's MAC address, not a wired ethernet MAC address. I was just wondering if the MB Air has a hard-wired (ethernet) MAC address, but of course it has no ethernet port nor the card for it. So no wired ethernet MAC address that could be used for traditional WOL. But given there is the Thunderbolt option for ethernet, I wondered if there were some kind of Thunderbolt ethernet MAC address. As it happens, I just found out that a Thunderbolt to Ethernet cable/adapter will have it's own MAC address, so unless you plug in such an adapter, the MB Air won't have a "wired" ethernet MAC address for WOL.

The MAC address is part of the Ethernet chip. Since your Macbook Air does not have Ethernet, it does not have an Ethernet MAC address. BUT if you get an Ethernet adapter (USB or Thunderbolt), then the adapter has an Ethernet chip in it, and that will have a MAC address. The MAC address is NOT part of the Thunderbolt bus, nor the USB bus. It is specific to the Ethernet chip. If you have multiple Ethernet ports (or adapters), each will have its own unique MAC address.

Not unless you are trying to wake up your Macbook Air, you do not need its MAC address. The MAC address for Wake-on-LAN is needed for the sleeping Mac.

Now if you want to use Wake-on-LAN for your Macbook Air, then assuming your Macbook Air is running Snow Leopard or newer, then you should be able to use the Airport WiFi's MAC address.

But this discussion was started for the Mac mini which does have an Ethernet port and an Airport WiFi, however, it is currently running Leopard 10.5 (or so I assumes as this is the Leopard forum, and you mention maybe you could upgrade it to Snow Leopard, or Lion). And because Wake-on-LAN for WiFi needs at least Snow Leopard, you are restricted to Ethernet. Whether upgrading to Snow Leopard will allow the Mac mini to use WiFi for Wake-on-LAN is unknown. If you want to experiment, you could install Snow Leopard on an external disk, boot the Mac mini on Snow Leopard and see if it will Wake-on-LAN via WiFi when asleep using the WakeOnLan app from your Macbook Air.

By the way, I would NOT upgrade to Lion on that generation Mac mini. I a rather old Mac mini that I tried running Lion on, and it was not good. I reverted to Snow Leopard, and it is very happy now. I just use it for a backup server, and Snow Leopard has been working fine for that (but I will say I have been thinking maybe I'll replace my old Mac mini with newer hardware soon, just not yet).

And if you get the above WakeOnLan app for your Macbook Air, you will be able to see the MAC addresses for everything on your LAN, complete with whatever names can be found.
