Done loading screen freeze

[sharkjfin]

When I launch minecraft, the game freezes of the done loading screen. I have looked at a lot of threads, but I have not yet found a solution. I tried launching it with magic launcher, but it still dident work, and came up with this log

 

*** MagicMinecraftLauncher 1.0.0 ***

I am on minecraft 1.4.7, and using forge 6.6.2.534 on a mac.

 

I do not have mc patcher, and I deleted meta-inf

Make sure you're running at least java6 and what archive tool are you using, the one that comes default with macs does not work with jar files correctly.

My software version for java is 1.5. And I have now tried several archivers, but it is still the same problem. If it is the java software , could you please tell me how to update the software. I have a mac osx 10.4.11.

Java 5 has been dead for several years now, Minecraft itself is even dropping support for it.

You need to update to at least java6.
