etrecheck help please mac running extremely slow post el capitan update
My mac has been running extremely slow since updating to el capitan. I've already uninstalled my security software, unplugged and restarted the computer, but nothing seems to help. Everything I try to do results in the beachball. Here is my etrecheck. I would greatly appreciate any help anyone can give me. Thank you!!!
