Well I technically use a mac.. it just hasn't booted up to Mac operating system in 10 months, no real need to since I can use Windows XP on it now. It's just I regret getting a Mac to inevitable just run windows, not to mention a PC would of been much better on the graphics-power-to-money ratio.

Anyways, good job on the program/hack!

As a person that gets asked a lot where people can find The MEF for there comp i have to say thank you for this and i really hope that you keep this updated. If you do i know i will be linking this thread in my threads for people to go to.

If your WoW is crashing, I need information like:

- What version of WoW are you using?
- What version of Mac OS X do you have?
- Are you using an Intel Mac or PowerPc Mac?

Also post the error that you get from WoW (put it on pastebin or something).
Without this information I'm unable to help you.

Mac OS X Leopard 10.5.6
Intel Core 2 Duo
WoW Version 3.0.9 (9551)

The MEF currently only works with WoW 3.1.1. I probably should have mentioned that in the main post. I do not have WoW 3.0.9 however if you upload the .app file I will make one for you when I get home (currently on my Ipod).

But no...

jjaa I was wondering If I could use your program in another program that I am making (I will include credits to you of course for the MEFIX part). I wanted to post here and ask you first before I just used it without your permission, furthermore, If it is possible could I see a copy of the source? I'm quite interested in model editing and memory editing on OS X but I'm not sure where to start. I have sufficient knowledge of Cocoa and some C++ but if you have any tips/pointers I would greatly appreciate it.

Cheers,

UPDATE:
In this release there are two versions. One is the old MEF from before (working with 3.1.2)the other is a new MEF that I made with Cocoa. As I a not confident with compatibility I have included both.

Instructions for new
1. Run the Model Edit Fix.
2. It will ask for administrator.
3. WoW will start up, you should get a message box saying success.
4. Close the Model Edit Fix.

Instructions for Old
1. Run the Model Edit Fix.
2. It will ask for administrator.
3. Run World of Warcraft
4. Close the Model Edit Fix.

From my Googling i can tell you that its something to do with Mac OS X v10.4.11. I will try find a fix.

You're welcome to use the same method as me in your program. Although without some reverse engineering experience you will most likely have trouble updating it across patches.

I will give you a quick run down of how i made the MEF. First I found the function that that Kynox uses but in the Mac binary. To do this I just look for something unique that would be in both the Mac and PC version of WoW eg. Strings and Function parameters. With a quick analysis of the function (at 0x4E14) it was obvious that the function was exiting WoW and dumping an error log. Seeming that this function did nothing else I decided to patch the first byte of the function to 0xC3.

0xC3 in x86 assembly is retn. The retn prevents the function from being executed and crashing WoW.

In order to patch WoW what you need to do first is obtain procmod/root (look at pocketgnome if you’re unsure how to do this). Next get the pid for WoW (again documented so no need to explain)..

mach_port_t wowTask;
int pid = GetPIDForProcessName("World of Warcraft");

// Now that you have the pid call task_for_pid
task_for_pid(current_task(), pid , &wowTask)

vm_address_t    addr = (vm_address_t)0x00004E14; // Our address
vm_protect(wowTask, addr, vm_page_size, FALSE, VM_PROT_WRITE | VM_PROT_READ); // so we can write to the address 
Byte buffer[] = { 0xC3 }; // The byte we want to write
vm_write(wowTask, addr, (vm_offset_t)&buffer, (mach_msg_type_number_t)1 ) //write to the address

Pardon my total ignorance, but once I've run the program and WoW is open, what do I actually do to patch anything? Do I just press f8 at the login screen, and if so, should anything visibly happen at that point?

Thanks for the help, and thanks much for making this!
