Hi all. I have a 2012 Macbook Pro which has developed an intermittent fault where without warning it just shuts down. I took it to a third party repairer in London and they came back with no fault found. The only thing they could suggest is deleting some data from the internal SSD (256GB with only 10 left). After some pruning I now have 50GB free, yet its still done it. I'm running an extended diagnostic at home now but wondered if anyone had any bright ideas what could be going on that the other company might have missed. Many thanks.
