Turning Off Rootless System Integrity Protection in OS X El Capitan 10.11 + The file(s) you see are the file(s) to move in step 5ġ. I see a bunch of text & numbers and GeForceTesla.kext. Determine which GeForce extension is being used: kextstat | grep ‘GeForce’ These are my notes from a similar (should.be.) problem with a 2011 MacBook pro:Ġ. If the problem is really in the Nvidia video card I wish to use it just like all other MacBooks pro IG, with the integrated card only for now as I will not be able to afford changing the whole board. I have a Macbook Pro mid 2014 and here is the Video Cards The moment I switch to any of the two options the macbook freezes. I googled and downloaded a program called gfxCardStatus. I am trying to find a solution how I can always use the integrated graphic card. I finally got to know that it was the GPU by trying to switch the mode in Energy Saver. I cannot install El Capitan again because whenever the download finishes in the App Store the macbook freezes. Hopefully the 'Internet Recovery Mode' worked and I got back to OSX 10.9.5 from El Capitan. I wanted to wipe out the whole drive and start fresh so I went to recovery mode and it I couldn't access it! It was just a total black screen. Sometimes when it's starting it works for the first few seconds up until it launches the previous open apps and it crashes again. The way it happens is that the mouse will freeze and everything else, there's nothing that works and all you can do is to do a hard restart. My macbook pro recently started to crash for doing random things, watching youtube on chrome, opening the photos app.
