The MacBook must be running (not sleeping) to be able to share its internal HDD on the network. I believe one way to do this is via System Preferences > Energy Saver. From there (I'm on Mountain Lion) I would recommend the following settings:
- Computer sleep: Never
- Display sleep: 1 min
- Put hard disks to sleep when possible (not checked)
- Wake for network access (checked)
- Allow power button to put the computer to sleep (not checked)
- Start up automatically after a power failure (checked)
The computer still went to sleep after I closed it. Looking around on the discussions, it works with Insomnia. Other discussions for Macbooks of this age suggest that the air intake is through the keyboard, and that the laptop could over heat. True? Perhaps the whole thing is better done with a real external hard drive?
This works when the computer is in Sleep, but still open. If the laptop is closed, no go. The article suggests using an external keyboard and monitor to get the computer to register w/ the proxy server, but I have neither of those things. Any additional suggestions?
Getting there, thanks for all the help!
