I need a fix for my mac book pro. Short of smashing with a sledge hammer I refuse to give up on my mac and replace it. Paying 2k for a computer should me a longer life. Using it has become eratic and it simultaneously shuts down. What files do I need to clear out and delete. I'm convinced it is software related. I had screen caps saved to my desk top and removing those temporarily helped but I need a permanent fix. The problem began with the mac shutting down and rebooting on it's own. It now still does that but the touch pad has become difficult and painful to use as the Mac has begun to ignore user input. I tried to remove some apps that have became defunct and nothing seems to permanently work. I think there is a dirty file jamming things up and it needs to be removed. Because of lack of control of the curser and windows logging in here is difficult and painful and challenging. Cache Files? Old crypto coin wallets? Macports and XCode? How do I find these and fully remove them? Thank you.
