This is likely happening due to OnMouseDown() logic only implemented via the 3D Physics system as of now.
- Use 3D colliders instead.
This may be happening due to your collision detection being set to "Continues Dynamic", as this is VERY expensive.
- Use "Continuous Speculative" instead.
This may be happening due to the collider and script containing
OnCollisionEnter() not being on the same object.
- Move the script containing OnCollisionEnter() to the same object as the collider.
This may be happening if you are using an unsupported Character controller..
- Use a rigidbody instead.
