I'm not a computer person but my understanding is that this it's what bricked my MacBook a long time ago. It worked perfectly fine. Not the fastest at seven years old but it was fine. Then along came a Google Chrome update with uncapped the RAM usage. Suddenly 8gb ram wasn't enough to do anything. Nothing else worked if the browser was open and I needed to multitask. Chrome was the only browser compatible with work software. Had to get another machine about a week later (not a Mac, that time).
