f.lux hanging system temporarily when changing

JohnEDee

I've been using f.lux successfully for awhile with no issues, but after upgrading to macOS Sierra, it seems to be triggering an issue where f.lux changes will hang the system for a few seconds after f.lux makes changes. Even the mouse pointer won't move at these times.

I downloaded an installed f.lux beta 39.7 but the issue is still happening.

Is there anything that I can do to help troubleshoot the issue?

Thanks,
John

Try disabling the profile writer:

Some apps do a ton of work when we install a system profile, but dual GPU macs still seem to need this to avoid flashing when switching between GPUs. (I am seeing less switching these days though.)

@herf I use a MacBook Pro (Retina, 15-inch, Mid 2014) and it doesn't have this f.lux Profile present in Displays > Color. There are a bunch of others there, however, presumably installed by default by macOS.

Interestingly, when I change to any of the Color Profiles in that list, the system does hang for a few seconds, just like when f.lux changes the color temperature.

Since I don't have a f.lux Profile in there, however, should I still try any of the suggestions in that article that you linked to?

Thanks,
John
