Madhyamaka, theravada and mahayana

Why is Mahayana Buddhism not a form of solipsism (epistemological, methodological, metaphysical) if the first school of Mahayana Buddhism was the Madhyamaka school from which then yogachara originated, which is considered solipsism? It turns out that the Madhyamaka school should be solipsism like Mahayana Buddhism itself, or I don't understand something? Also, why is theravada Buddhism not solipsism (methodological, epistemological, or metaphysical) if the Terevada doctrine is completely dependent on one's own experience and awareness? Thanks you
