Blue screen tint with Yosemite 10.10.1 - MBP 15" Mid 2010 Model 6,2
Who is having this issue, have you resolved it, and how did you do it: Coinciding with Yosemite 10.10.1. my entire screen has begun to take on a blue tint. This was not an issue with 10.10.0. This is a MacBook Pro 6,2 with 4GB system RAM. Graphics is with built-in Intel HD Graphics (and standard 288MB VRAM), and the standard NVidia GeForce GT330M graphics in PCI (and 256MB VRAM).
The blue cast appears when using Microsoft Outlook 2011 (back to normal when it quits), Adobe Photoshop CS6 (sometimes yes, sometimes no), and intermittently when running Firefox or Safari (where the blue cast seems to coincide with invoking plug-ins). All of these applications are up to date.
Attempts to resolve this include:
1) Downloaded and installed the latest software updates for Outlook, Photoshop, Firefox and Safari. Made no difference.
2) System Preferences -> Displays -> Color -> Calibrate. I initially thought that the Color Sync profile had been corrupted, but the color was so 'off' that my attempt to manually recalibrate the screen could not go far enough. So I abandoned this.
3) System Preferences -> Energy Saver -> Automatic Graphics Switching. Checking Automatic Graphics Switching works, but un-checking it and the blue cast comes back immediately.
4) Running Disk Utilities -> Repair Permissions. Didn't work.
5) Cleared all caches using Onyx: Worked for 10 minutes, then blue came back
6) Reset PRAM: Worked for two days, now the blue is back.
