I stumbled on your postother posts about the Ridiculously Slow Macbook pro 2013 that you assisted a user with,That were remedied by replacing the harddrive cable. I am dealing with agonizing sluggish behaviour on my mac, It seems to be the same issue as the one you dealt with, however however as you know 2015 macbook pros have SSD's.. do you think its about replacing my SSD? as opposed to a cable swap.
I am desperate for help, I can't use my computer...
can you help me figure out what to do?
thank you so much man
