How to update Cocos2d-x framework

HI,
i would like to update my cocos2d-x v3.3beta0 framework to cocos2d-x v3.3rc0 .
Please help me.
Thanks

I am just remove old files from cocos directory and add new files from last version. I am not sure but on mac os 10.9.5 it works fine

But i have use git to clone it, so i would like to use git commands to update the framework or any other command.

then try git pull inside cocos directory
in console :
cd path/to/cocos/directory
git pull

it doesn’t work, because i made changes in the cpp tests project.

ok. then remove test project folder and run:
git add .
and after
git pull
