unity-crashes-after-setting-project-permissions

I've just downloaded Unity, I have got a problem during lauching it, which crash just after choosing the project. Before crashing Unity propose to change file permission on project directory.

However everybody can read write and execute on the project directory, I set it manually.

I'm not alone to have this problem : http://answers.unity3d.com/questions/1618/unity-crashes-after-setting-project-permissions

I work with a macbook pro with snow leopard, using case sensitive file system.

Could you help me.

Please file a bug report. And please do not add questions that have already been asked as this just clutters Unity Answers. In the question you have linked, everything that can be said about this issue (for now) has already been said. I hope they'll find and post a workaround soon (and an actual bugfix, of course).
