Unfortunately, it is too late now to induce vomiting. Both macadamia nuts and chocolate are toxic to dogs. Now you can only just treat the symptoms. Look for diarrhea, could be lethargic or hyper, vomiting, etc...
Is she vomiting or have diarrhea? If she is not showing any difference in behavior or displaying symptoms then she will be ok. I've heard of pups getting into some pretty toxic things but not always a cause for panic. Just keep an eye on her.
If your dog isn’t showing any signs of illness then I wouldn’t be worried. My dog got into nuts before and ate a whole pan of double chocolate brownies and was also fine. Only time he wasn’t was when he got into the trash and ate a rotisserie chicken carcass…he was super sick but didn’t need the vet.
I would call vet if it's showing any signs of lethargy, diarrhea or not acting normal. Even a simple Google search will tell you they are highly toxic to dogs and that's just a lil guy.
