Alright, so originally that wasn't developed with the Mac version of D2 in mind. If you're up for some testing, grab some .plist or .pref editor and play around with it. It may be that you can edit one of the D2 plist or prefs files and add the same reg key to it with the same value.
The Chat Gem Lives!

Also, home channel support (Join a private chat channel upon Battle.net login.)
1. Go to Start > Run > type regedit
2. Navigate to "HKEY_CURRENT_USER\Software\Blizzard Entertainment\Diablo II"
3. Right-click in the right-hand pane, select "New -> String". The name of the Key should be "Default
Channel" The value is the channel name.
How would Mac users achieve this?
Under OSX the game saves it's setting in the preference files "Battle.net Preferences" and "Diablo II Preferences" who are located in the Mac users home directory.
Absolute pathname: /Users/<your username>/Library/Preferences
CAUTION! You need an mac ressource editor to open and edit those files. A plain text editor won't do!
I used an ol' ResEdit to do it.
Open "Diablo II Preferences" with the resource editor and double-click the icon named HKEY. It will open a list with windows-like registry entries named "HKEY_CURRENT_USER\Software\Blizzard Entertainment\Diablo II\AllowHardcore" and such.
Next you best duplicate an entry to create a new key with copy and paste.
Next get this new keys' resource info and change it's name into "HKEY_CURRENT_USER\Software\Blizzard Entertainment\Diablo II\Default Channel". Then close the edit window.
Next double-click the renamed resource to change it's data. My ResEdit showed me a hex-editor like entry field, so this is what i had to enter:
If you also duplicated an entry any old data you see needs to be deleted first.
Now start by entering "00 00 00 01" in hex mode.
Then switch to decimal/text mode and enter the channel name you want the game to end up in.
Finally switch back to hex mode and add a final "00".
Now save and close the resource file.
Your game will now enter chat in the channel you want it to.
Venture to the Realms Beyond to get off the beaten path.
