Ok, after testing for a while I can now write these instructions.
Tested and working on current 4.3.4 streaming mac client. (2:00am 20/04/12)Step 1:
Install your streaming client until the PLAY button is highlighted and the notice "World of Warcraft is up to date" appears. (Even though it isn't truly up to date)
Run "World of Warcraft.app" once, pass through those terms and conditions, confirm your client is functioning.
(Besides, you can either risk your life on making up from the Windows one, and assume "Data" of both enUS Windows and enGB Mac are identical.)Step 2:
Since 4.3.4 is ready, you can start "patching" now.
I recommend you get the original "World of Warcraft.app" instead of this. (I have no idea whether this is patched or non-patched). But this is the only choice in the mean time.
Now, get the file from http://speedy.sh/7f2tP/download/WoW-CN-Mac-433-2736.zip
Extract it, delete the file "World of Warcraft Launcher.app" RIGHT AWAY. No, you don't need it or it would blow your whole computer up. Remember to empty trash just in case it could run back somehow.Step 3:
Create a new folder inside Applications/World of Warcraft and name it "Backup".
Move the current 4.3.4 "World Of Warcraft Launcher.app" and "World of Warcraft.app" into that "Backup"
Right-click to Applications/World of Warcraft/Data/enGB (or your language version)/realmlist.wtf
Select "Duplicate" and rename the duplicated file to realmlist.wtf.bak. (self-explanatory)Step 4:
Right-click to realmlist.wtf again, select Open With/Other/TextEdit.
Change the content into:
set realmlist cn.logon.warcraftchina.com
set portal cn
Leave the second and third lines untouched.Step 5:
Copy "World of Warcraft.app" you got from the archive into wow folder.
Make sure you have no any sort of launcher in your wow folder, or you will be screwed up.
Copy the "Fonts" from your Windows wow folder, and "AddOns" as well.
I also recommend using 64-bit client (functioning pretty well on 4G RAM Lion)
Direct link: http://us.media.battle.net.edgesuite.net/downloads/wow-installers/live/WoWLive-64-Mac-15354.zip
Just simply extract the content into your wow folder. No harm/virus/explosion detected.
Drag your desired wow.app to the Dock, to make shortcut.
Left-click to that W portrait.
Enter your Account name and password.
And now, you're in. But not yet.Step 6:
You will notice at the game menu button (esc) that the client is still being downloaded. Don't panic, this is a very normal situation.
Now quit your dedicated playing.
Revert everything back to the original 4.3.4 version.
(Copy those wow and launcher back into wow folder, move that 4.3.3 wow to Backup, rename realmlist.wtf to .bbk. Rename realmlist.wtf.bak back to realmlist.wtf.)
Run "World Of Warcraft Launcher.app".
There will probably be about additional 6 GB to be downloaded. So have your patience.
When it's done, change your files back to the Chinese "patch".
Execute either wow.app or wow-64.app and now you're ready for raiding.
If you're using 64-bit version, you will gain these benefits:
1. Compatible and beautiful graphics.
2. Stunning sound quality. (Recommend the Sony MDR-V300 headphone with headphone mode on)
2. Lightning speed loading bar. (Not including the first time playing)
3. Lag-free gaming experience. (Well, depends on when you play and where your char is, but really improved)
1. Risk-free updates in the future.
(Just have your former "World of Warcraft.app" backed up and you're free to update)
2. No bloody Chinese in-game patches/errors/failures required.
YY installation on iOS devices is the most convenient so far. Or Android devices also work perfectly.
