Abnormal display reation in my MacBook Pro.

[Bezoya38]

Hi,

For a few days my screen reacts strangely. Sometimes, the edge of the screen lights up and then fades out, like taking a screenshot (does not emit any sound).

I don't know if it is a hardware problem or if I have been hacked. Has something similar happened to anyone?

I have a 2011 macbook pro with Sierra.

I hope you can help me. Thank you

is it a 15" MBP? If so, it may be the dGPU failing. As I'm sure you know the 2011 MBP that uses a discrete GPU has a known issue where it will fail eventually.

No it is a 13'' MBP.
