El Capitan makes my Mac run very slow, need some help?
I Upgraded my MBP (2014), from Yosemite to El Capitan and it slowed my Mac down to the point where it became totally unusable. I also tried to repair the permissions, and even reinstalled OS X El Capitan from Time Machine, but it didn't help. My MBP is crawling, and I'm hoping someone can walk me through a solution. Need help.
