      Due to a driver bug in Intel GPUs, people with new Macbook Pro (2018) and Intel GPUs are seeing black colors rendered as cyan when f.lux is running. This has been fixed for quite some time in Mojave, so if you are willing to run a beta, that is one way to fix it.

      If you cannot update to the Mojave beta, we have posted a workaround here:

      https://justgetflux.com/mac/Flux39.9871.zip

      The build has a new pref called "blackbias" which pushes up the blackpoint to work around the bug

      Steps:

      • Quit current f.lux
      • Download/run build above

      Then:

      • From Terminal type this into the command line:

      defaults write org.herf.Flux blackbias 0.05

      The default is zero, which you can get back to this way:

      defaults delete org.herf.Flux blackbias

      Some people have needed to use 0.1 instead. This is a bandaid until we have a better fix from Apple/Intel.

              The cyan is back again on MacBook Pro 2018. The fix solution works, but sometime the black still blur to cyan.

                @cehck I found this happened only on the display screen of MacBook Pro, but my external monitor (dell 2518D) seems working fine, no cyan color.

                    Okay, that seems to work for me. Do I need to remove the defaults setting after upgrading to Mojave? Or will it be ignored automatically?

                      If you kept this build you would have to reset. If we do another update, we will turn it off then.

                        @herf Good evening!

                        I just installed flux on my macbook pro '18 and as mentioned in this thread, the blacks turned cyan. I uninstalled flux and everything still was cyan so I restarted my mac. The system crashed and I keep getting crash reports every time I restart. Tried if logging into guest account works but that is also not functioning. Is it possible that this issue was caused by flux?

                        Help would be very much appreciated! (Thanks in advance)

                          I just installed this version of Flux on macOS 14.1 Mojave on my MBP 2018.
                          After that, the problem was fixed. I use it only for blacking the Menu Bar and for And I use 'darkroom mode' to make the screen red.

                          For 'yellowing' the screen I use Nightshift now.

                          One nice option for Mojave would be that Flux switches automatically to dark mode at nightfall (or at a given time) and to light mode at wake up time.
                          I just notice that this is already done !

                            Worked for me - thank you for creating a separate thread on how to get rid of the cyan colors on Mac OS. Hopefully there'll be a fix in the future from Intel or Apple that fixes the bug.
