Hide SSID of an ad-hoc MacBook pro network
Solution 1
It doesn't appear to be possible to setup an Ad-hoc network without SSID broadcasting, at least not with through the System Preferences / Sharing / Internet Sharing controls....
You can change the channel, you can change password, and encryption, but I don't see a way to tell it to not broadcast your SSID.
One option, would be to use an Airport Express, it's a low cost alternative, and does allow you to choose an hidden SSID.... After all, hidden SSID's are really more of an router feature.....
Solution 2
It doesn't make much difference if you broadcast it or not.
Sure, it is easier for a novice to detect if you are broadcasting, however it is trivial to detect networks even when their SSIDs are disabled. Don't rely on this for security - setup a good WPA password and whitelist the MACs of the systems allowed to connect.
This will give you all the security you need.

I have a MacBook Pro, with which I share my ethernet connection over wifi. However, I would like to hide the ssid of the generated ad-hoc wifi network.
How would I do this?

Admin over 14 yearsInteresting question. I used fseventer to see what files get modified when ad-hoc networking is enabled, and it doesn’t appear to save that information to the filesystem—at least not right away. If it did, there might be a
.plist
file you could tweak.

Austin Hyde over 14 yearsI don't want it for security, I just don't want to advertise I'm sharing my wifi. If anyone really wants to use it, it would be easy to discover it, but I do have a password set already. On another note, how does that answer my original question? I want to know how to hide it. NOT what the benefit is.

Konrad over 14 yearsHow does hiding your SSID prevent your wifi network from being advertised?! That was what I was trying to point out, it won't fool anyone.

Austin Hyde over 14 yearsI don't want to fool anyone. I just don't want it to show up in the casual passerby's listing of networks, even if I do have it passworded.
