Hi..again if you have seen my post. hahaha. Anyways, a week into my new macbook (bought it in may) this happened after I opened it from sleep. The screen was totally unresponsive but I could still move my mouse. I had to force reboot it. I went to the applestore and they said they couldn't detect anything wrong and I should record a video the next time this happens. It hasn't happened recently but I haven't been using it all that much since then. Like a couple hours since that happened. Should I push for a replacement regardless as something like this shouldn't be happening anyways? Or is it just a one off case? Thanks!
