ugh. Is that caused by a bad screen or bad graphics card?
Or a bad ophthalmologist???
From what my understand is, Apple got a batch of bad graphic chips. . . and will be replacing the logic boards that contain them since it is integrated graphics on the logic boards.
About 1-1/2 years ago I took my son-in-law’s MacBook Pro into Apple for service. The screen was totally dark. Even though it was well beyond warranty being a couple years old, they fixed it free of charge. It was a bad graphics card, and they were offering to fix them for free by replacing the graphics card. Great customer service.
It is caused by investing in the "perfect and macboxen-uber-alles" hysteria.
Real computers are rarely infested with such problems, and if some script-kiddie manages to find some weakness with any particular OS, it is usually the 'nix coders that rapidly respond and fix the problem.
Macophiles, on the other hand, prefer to think of these as merely a new "feature", rather than admit that their precious macinses can be hobbled in any way, shape, or form (my precious) because their macmachines are impossible to corrupt.
Oh, look, I need to print out another calendar -I had better call someone local that has a mac to beautify it and print it out. *snicker*
Then when I want to get some truly real work done instead of bloody cartooning, I will work on these Engineering projects on a real computer with a REAL and WORKING installed OS.
Then again, I do have some photos that need adjusting, so maybe the two or three people that are liberal and wealthy enough to play with macs can help out if I promise to say nice things about Hitlery -I mean, "Hillary" (*cough* "Mrs Bill" *cough*).
If I have to.
