Nice!

What's the problem? I can run HelloCpp correctly on mac book pro retina.

Enable OpenGL for High-Resolution Drawing

Your second image seems incorrect.

Because HelloCpp proj.mac

bool AppDelegate::applicationDidFinishLaunching() {
    // initialize director
    CCDirector* pDirector = CCDirector::sharedDirector();
    CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();

    pDirector->setOpenGLView(pEGLView);

    // Set the design resolution
    pEGLView->setDesignResolutionSize(designResolutionSize.width, designResolutionSize.height, kResolutionNoBorder);

    CCSize frameSize = pEGLView->getFrameSize();

    vector<string> searchPath;

    // In this demo, we select resource according to the frame's height.
    // If the resource size is different from design resolution size, you need to set contentScaleFactor.
    // We use the ratio of resource's height to the height of design resolution,
    // this can make sure that the resource's height could fit for the height of design resolution.

    // if the frame's height is larger than the height of medium resource size, select large resource.
    if (frameSize.height > mediumResource.size.height)
    {
        searchPath.push_back(largeResource.directory);

        pDirector->setContentScaleFactor(MIN(largeResource.size.height/designResolutionSize.height, largeResource.size.width/designResolutionSize.width));
    }
    // if the frame's height is larger than the height of small resource size, select medium resource.
    else if (frameSize.height > smallResource.size.height)
    {
        searchPath.push_back(mediumResource.directory);

        pDirector->setContentScaleFactor(MIN(mediumResource.size.height/designResolutionSize.height, mediumResource.size.width/designResolutionSize.width));
    }
    // if the frame's height is smaller than the height of medium resource size, select small resource.
    else
    {
        searchPath.push_back(smallResource.directory);

        pDirector->setContentScaleFactor(MIN(smallResource.size.height/designResolutionSize.height, smallResource.size.width/designResolutionSize.width));
    }

    // set searching path
    CCFileUtils::sharedFileUtils()->setSearchPaths(searchPath);

    // turn on display FPS
    pDirector->setDisplayStats(true);

    // set FPS. the default value is 1.0/60 if you don't call this
    pDirector->setAnimationInterval(1.0 / 60);

    // create a scene. it's an autorelease object
    CCScene *pScene = HelloWorld::scene();

    // run
    pDirector->runWithScene(pScene);

    return true;
}

mac is iphone?ipad???? why setDesignResolutionSize???

bool AppDelegate::applicationDidFinishLaunching() {
    // initialize director
    CCDirector* pDirector = CCDirector::sharedDirector();
    CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();

    pDirector->setOpenGLView(pEGLView);

    // turn on display FPS
    pDirector->setDisplayStats(true);

    // set FPS. the default value is 1.0/60 if you don't call this
    pDirector->setAnimationInterval(1.0 / 60);

    // create a scene. it's an autorelease object
    CCScene *pScene = HelloWorld::scene();

    // run
    pDirector->runWithScene(pScene);

    return true;
}

is ok,retina image*2

Sorry, I don't understand what you meant.
Maybe you should refer to http://www.cocos2d-x.org/projects/cocos2d-x/wiki/Multi_resolution_support.
