Hey I wanna give a quick update, I think it might help some people.
I've posted about two months ago on having multiple complete freezes when trackpad dies, screen is alive but can't interact and the only way to fix is a hard reboot. That happened 4 or 5 times in the span of a month or so.
I haven't been having those kind of freezes in a long time. I have a strong assumption of what it might have caused them.
I originally thought it was a graphic card issue of some sort, since that would mostly happen when watching videos, but I decided to bring it to the apple store and the genius dude told me there are generally three reasons of why that would happen.
1) Disk (physical) corruption (in that case you'd need to change it)
2) Disk Partition corruption (a full blown reinstallation should do the trick)
3) Sometimes using cracked adobe products (yikes, I feel like that might be my case, since in the two months I haven't used those programs I haven't had any crash)
