OSX OpenGL 4.1 glEnableVertexAttribArray glDrawArrays GL_INVALID_OPERATION - c++

Question

I programmed an OpenGL application with an SDL window. Core Profile running OpenGL 4.1 on a Mac OSX 10.9. The command glClearColor works great and I get the right color on screen. But inside my renderer I got the GL_INVALID_OPERATION error everytime I execute the commands glEnableVertexAttribArray and glDrawArrays.
That is the code:
Vertex Shader:
#version 410
in vec4 position;
void main(void)
{
gl_Position = position;
}
Fragment Shader:
#version 410
out vec4 out_Color;
void main(void)
{
out_Color = vec4(0.0, 1.0, 0.0, 1.0);
}
All shader compile and linked to an program. No linking error!
Creating buffer with data:
static const float VertexBufferData[] = {
0.75f, 0.75f, 0.0f, 1.0f,
0.75f, -0.75f, 0.0f, 1.0f,
-0.75f, -0.75f, 0.0f, 1.0f,
};
glGenBuffers(1, &m_VertexBuffer);
glBindBuffer(GL_ARRAY_BUFFER, m_VertexBuffer);
glBufferData(GL_ARRAY_BUFFER, sizeof(VertexBufferData), VertexBufferData, GL_STATIC_DRAW);
glBindBuffer(GL_ARRAY_BUFFER, 0);
Render:
glUseProgram(m_ShaderProgram);
glBindBuffer(GL_ARRAY_BUFFER, m_VertexBuffer);
glEnableVertexAttribArray(0);
glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0);
glDrawArrays(GL_TRIANGLES, 0, 3);
// glDrawElements( GL_TRIANGLES, 3, GL_UNSIGNED_INT, nullptr);
glDisableVertexAttribArray(0);
glBindBuffer(GL_ARRAY_BUFFER, 0);
glUseProgram(0);
Output:

AS BDL already said: The solution is to create a VAO. As a short description: A VAO (Vertex Array Object) is a collection of VBOs, which describes the vertex layout and the vertices for the shader.

So I have changed the following code blocks:
Buffer:
static const float VertexBufferData[] = {
0.75f, 0.75f, 0.0f, 1.0f,
0.75f, -0.75f, 0.0f, 1.0f,
-0.75f, -0.75f, 0.0f, 1.0f,
};
glGenVertexArrays(1, &m_VertexBufferArray);
glBindVertexArray(m_VertexBufferArray);
glGenBuffers(1, &m_VertexBuffer);
glBindBuffer(GL_ARRAY_BUFFER, m_VertexBuffer);
glBufferData(GL_ARRAY_BUFFER, sizeof(VertexBufferData), VertexBufferData, GL_STATIC_DRAW);
glEnableVertexAttribArray(0);
glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0);
glBindVertexArray(0);
Render:
glUseProgram(m_ShaderProgram);
glBindVertexArray(m_VertexBufferArray);
glDrawArrays(GL_TRIANGLES, 0, 3);
glBindVertexArray(0);
glUseProgram(0);
Result:
