MacBook Pro Screen Goes Blue
If you’ve got a MacBook Pro from Apple, including the shiny new ones like mine, you might have noticed a strange problem in which you screen tints blue after being on for some time. I can’t really take a screenshot of it, but everything works fine with a slightly blue (cyan?) overlay. It’s only happened twice since I’ve had the machine (about a month of heavy use), so it’s a pretty infrequent occurrence.
I did a little Googling this evening and found a post on leyton.org with a fix that worked perfectly for me. I don’t use Fast User Switching on this machine so I don’t think that’s the problem, but running the DMProxy command immediately cleared the blue. Bookmarking it here for everyone else with the same problem, and for myself next time I forget that I’ve created a fixtint alias
Anyone know what DMProxy actually does?
