MAC OS Unexpectedly Quitting. . .
I've been having a bit of a problem. From time to time, my computer screen turns dark descending from the top of the screen to the bottom, and an error message pops up saying that I will have to restart my computer. I've run the disk first aid, and it says that no repairs are needed.
Any ideas?
Thank you,
John
