Hi, So about once a week my rMBP will just freeze on me, everything becomes unresponsive and I have to force restart the Macbook, however it boots in about 10 seconds and runs fine after that. Someone suggested it could be something to do with Adobe Flash however the last time it froze I was on a website with little to no flash (ultimate guitar). I wondered if it was a lack of storage, however I still have 65GB of storage left. Does anyone know why its doing this? Many Thanks.
