Question: iMac display colors wrong after update to 10.13.1
Have a 27" late 2012 iMac which I updated to 10.13.1
My display colors are off, the screen looks dull and sort of purple. So I used my Spyder calibration tool, it changed a little but the colors are not correct. Any idea?
iMac, macOS Sierra (10.12.4), late 2012 27 inch iMac, 24 GB
