I have a 2016 Macbook Pro running Catalina that has a 250gb SSD. My SSD has 245gb used currently shown on its disc utility. My computer has almost ground to a halt and seems unable to download anything or process anything. What can I do to get my Macbook Pro computing capability back? I realize that I should have had a backup routine that would have never allowed my getting to this point and that will now happen, but how do I move forward from where I am now at?
I am now engaged in photo editing as a business and my Macbook Pro is so sluggish in performing any editing functions it wastes a lot of my time in doing what I need to do. I need my computer to be back to the wonderful level of functioning and performance that I enjoyed when I first bought this device.
