[SOLVED] Mac Graphics Issue

[PeppermintFangs]

I have an early 2011 Macbook Pro 13" and I've been dealing with a graphical anomaly.

As you can see, some pixels are pink, green, or yellow in places they shouldn't be. It only seems to be reacting to certain colors, as clicking and holding to drag a blue box over the screen changes the pixels that are affected.

Strangely enough, this is not a display issue. When I switch over to my bootcamp side, there are no pixel anomalies whatsoever. If I connect an external display to my Mac, once again there are no anomalies.

Can anyone help me troubleshoot?

Artifacts can appear for various reasons, though I won't get into the details. That said, which version of OS X are you running? Have you tried resetting the NVRAM or SMC?

I'm running version 10.9.5. I've been working on upgrading it to El Capitan for some time.

I did try to reset the NVRAM, but not the SMC. How do you do that?

If resetting both the SMC and NVRAM don't work, then, you ought to try repairing system permissions, clearing out the cache, and general maintenance -- I suggest using Onyx (free) to do this.
