Critical Error when logging in?

[Melrak]

On my 2010 Macbook I always get this error pop when logging in.

Assertion Failed!

App: /WoW TBC/WoW TBC.app
File: /Volumes/F2/usrbuild/xb/build/WoW_8606patch2.4.3/WoW/Source/Mac/../Object/ObjectClient/Movement.cpp

Assertion: CMath::fnotequal_(init.runSpeed,0)


What should I do?

What version of Mac OS X are you running? Because if it is above Lion, 2.4.3 no longer runs natively in OS X due to a glitch (but oddly 1.12 and 3.3.5a do).

You'll need to download the Windows version on our site (first link) and emulate the game through PlayOnMac.

10.6.8 Snow Leopard. So I can download 2.4.3 again?

Snow Leopard should run it perfectly fine... Hmm... If you can find the native client still it should run just fine!
