Long story short, wanted to reinstall the OS cos it was acting up, performance-wise. SuperDrive hasn't functioned in years, so that's a no. Remote Install via PC doesn't work, this feature is limited to MacBook Airs. And finally, an external DVD drive didn't do the job, cos even after starting install - once it reboots, something in the OS tells it not to read from the external. Hours were put into these attempts! Is there any other possible way to reinstall Snow Leopard??
