Hi there,
I have been getting this strange error message on my iMac. It has happened a few times in the past couple of weeks. Out of nowhere the screen will get kind of dark, then flash to its original color, and then this error message appears. I have been a mac user for years and years and have never seen an error message such as this, so I am slightly worried. Anyone have any idea what this is? Or know if I should be worried about this...?
Attached is a screen shot of this strange error message. Thanks!
