Yesterday for no apparent reason when I logged back into Yosemite after my computer went to sleep, everything turned pink. I am not the only one to have this problem. It has been observed in Mavericks as far back as July of this year. Though I am happy it is not an issue with my monitor I would still like to correct this issue. Any suggestions would be appreciated.
Hey there William,
It sounds like your monitor is taking on a pink hue when waking from sleep. I would use these steps from the following article, named:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
- Start up in Safe Mode.
- From the Apple () menu, choose System Preferences.
- Choose Displays from the View menu to open the preferences pane.
- Select any resolution and refresh rate that your display supports.
- Restart your computer.
Thank you for using Apple Support Communities.
Cheers,
Sterling
Display Turns Pink
