My screen has a bunch of purple and cyan flickering bars on it. Does anyone know if there is a fix for this? I have tried resetting my nvram. I closed my lip for 15 minutes and then when I opened it, these lines appeared. I also run a diagnostics, but there were no hardware issues found.

  • Apple offers FREE diagnosis and cost estimate. Start in Safe mode (no graphics just text)

  • @Ruskes You get graphics in Safe mode. You may be thinking of Single user Mode.

  • Try a safe boot. Shutdown your machine. Hold down the shift key. Poweron. The boot up will take longer than normal because the filesystem on the startup drive is being checked and repaired as needed. All about safe mode including what features and apps safe boot leaves out. Safe boot uses a software driver instead of using your machines video hardware. support.apple.com/kb/ht1455

Sorry to say that looks an awful lot like a hardware error.

It could be a bad video card, issues with the screen itself or the connection between the two (cables, connectors, etc.).

If you boot into recovery mode is the issue still present? That would rule out an issue with your OS if it is still there.

My advice, seek the help of a qualified Apple tech. Either at an Apple store or a good 3rd-party Apple certified repair center.
