Macbook Pro screen becomes blue every time a discrete graphics card is used!

Weird! I turned on FileVault 2 just days before finding this thread and noticint the blue tint issue. I haven't had any problems since I posted here on 10 November, but I had no problems at all with this before I turned on FileVault 2.

You're probably right.

FileVault 2 is definitely one cause of this issue. I rebooted 7 times with it off, no blue tint. I turned it on and immediately logged in, launched the iOS Simulator (which always triggers this issue as it uses discrete graphics) and sure enough, blue gamma.

For those of you using an application to force to internal video, I would suggest against that. You are losing the performance of the discrete video that you paid for. Until Apple fixes this issue, just log out and back in after a reboot. This is less painful if you have an SSD than if you have a HDD, but it does correct the issue vs. crippling the performance of your computer.

Yeah, FileVault is *a* cause but I am fairly certain not every cause of this issue. I think FileVault just messes with the order at which the OS loads color profiles.

Yep same here, FileVault is disabled, still get the issue. So far I have two workarounds:

1. With Automatic Login enabled, let the machine start and then Logout and backin

2. Disable Automatic Login and enter password to login.

I've been using option 2 for the last 5+ weeks, annoying as I prefer Automatic Login but entering the password is still better than the blue tint.

Still believe it's to do with the speed or order in which the colour profiles are loaded when started.

Could be - I had not thought of that one... but, I don't know, changing color profiles doesn't solve the problem. I am going to note your "Automatic Login" 'fix', though. If it comes up again, that's the first question I'll ask.

Good call,

I have the same issue on my new MacBook Pro 2012, and Apple Customer Service in Germany told me that this is normal...but i say THIS IS NOT NORMAL, this is a problem for me (i am photographer).

Apple do something!

Yeah I'm a photographer too and it's a huge issue. I don't have FileVault turned on, so that's not a fix for me.

same problem!!

this better be fixed by the next update! look at all these replies!

i will log on and off for now, but man!

i dont want to forget about this and be working on a project in photoshop!

this could screw over a lot of photographers and graphic designers!

15" early 2011 macbook pro 10.8.2

Same here!

Hey, Apple! Where is your quality?!

My diagnosis was to chance my logic board, but this is a very expensive move if you don't have Apple Care anymore... My MBP is a paper weight rigth now.

Hi.

Just uninstall/reinstall the latest version of Adobe Flash. That was the fix for me...

Uninstall:

Re-installing 10.8.2 combo update (http://support.apple.com/kb/DL1581) fixed this problem for me. MBP 17" early 2011.

Are you sure about this? When I upgraded to 10.8.1 I thought the same, but after a full shut-down and restart the issue came back. I also tried the re-installing trick for 10.8.1 which seemed to work but again after a shut-down and cold start-up the issue came back.

Note, putting the machine to sleep is not the same. When I thought the problem was fixed I let it sleep many times and the blue tint never came back, thought the issue was finally resolved, that was until I actually shut it down and started up a few hours later, and the tint came back.

Sorry, I posted too soon. The problem is back. It wasn't there after first shutdown/restart after re-installing 10.8.2, but came back after full shutdown.
