sierra dock text highlight

Hi, I have MacBook Air (13-inch, Early 2015), which I bought with El Capitan on and a couple of weeks ago I upgraded to Sierra. Since then, it does this annoying highlighting of the text on the dock, which I cannot make go away. The highlight sometimes is lighter or darker shade of gray, sometimes pink, and sometimes it is black so one cannot even read the text. If I restart it looks ok for a while and then it just happens again. Anyone have an idea? Thanks in advance!

I have finally found the solution to this problem! While "reducing transparency" in accessibility solves it when on, A permanent solution can be found by going to your display preferences, then the color profile tab, then deleting your color profile/recalibrating it to your native white point.  problem solved.

I don't know why it's happening. I thought it might be related to either your Desktop & Screen Saver selections or "Use dark menu bar and Dock" selection but I have been unable to duplicate it.

All I can suggest is "Safe Mode" and the creation of a temporary User Account so that you might be able to isolate the cause:

1. Try safe mode if your Mac doesn't finish starting up.
   • Compare how your Mac works in Safe Mode to how it has been.
   • Then, restart normally. If the same problem returns, please read the section If an issue doesn't happen in safe mode for Apple's recommended actions.
2. How to test an issue in another user account on your Mac.
   • When you are finished troubleshooting, you can remove the temporary User Account by following these instructions: macOS Sierra: Delete a user or group.
   • Before removing it, confirm you don't need any of the files you might have created in that Account.

Just a wild idea (like John Galt I´ve no idea why this is happening) but have you got installed or are you using an app called "cDock"? This is a programme that lets you do all sorts of customisation of the dock, and it might not be compatible with Sierra and so causing problems. Maybe search for and de-activate/delete it (see if it´s maybe running by opening Activity Monitor), re-boot and see what happens!

But you can also quickly and cleanly restore the dock to Apple´s default settings by using Terminal, and this will also remove all folders, aliases etc. you´ve put in the dock!!

Open Terminal and at the prompt type exactly:

defaults delete com.apple.dock

Then press Return and type:

killall Dock

Quit Terminal and re-boot! Hope this helps you Cheers, Ian.

Also having this issue (and has no solution). It's really weird, that this topic is the only result I have found so far.

I am having the same issue. Is there any solution available?

It just started a couple of days ago. I have macOS 10.12.1.

Not only I cannot solve this, but now it has started doing it in applications too...

I have the same issue and started my own thread before finding this one.

I've discovered two things, perhaps clues to the cause, that are reliably repeatable...

1.  When I go to System Prefs > Accessibility > Display section.  When I turn ON the "Reduce Transparency" option, the anomaly goes away.  Then when I turn the transparency option back to its default, which is OFF, the issue always comes back.

2.  When I log out and log back into my user account, the problem is gone.  Then upon shutting down and rebooting the machine, the problem always returns.

Here's what I've done:

1.  Trashed the Dock prefs file and reverted to default Dock settings.  The problem persists.

2.  Booted into Safe-mode.  The issue was not there, however, this means nothing because Dock transparency happens to be automatically disabled in Safe-mode.  The "reduce transparency" option removes the issue entirely in all cases, and in Safe-mode, the "reduce transparency" option does nothing since there is no transparency in the first place.

3.  Booted into another Admin account and the problem is there.  There are no startup items.

4.  Booted back to the original account after Safe-mode and the problem continues.

Your procedure does not permanently fix the problem.  It always comes back on reboot.  However, killing/restarting the Dock will fix the issue, but only until the next reboot.

Now I'm starting to see this too.  Annoying. 

I have finally found the solution to this problem! While "reducing transparency" in accessibility solves it when on, A permanent solution can be found by going to your display preferences, then the color profile tab, then deleting your color profile/recalibrating it to your native white point.  problem solved.

Thanks, worked for me as well !!!

Switching from one profile to another, then back seems to also fix the problem, at least immediately...

Thanks - these are pretty resourceful suggestions, but unfortunately they don't fix the issue for me.

The first one - reducing transparency, which seems to work for most here - doesn't really eliminate the issue on my screen. It goes a long way: the difference between the highlighting and the background of the label is much smaller than before. So now it doesn't quite show like before. I'd say this is a decent improvement, not a fix. At least on my hardware.

The second one amounts to throwing away the baby with the bath water. I have deliberately hardware-calibrated my Eizo CG243W monitor to a whitepoint of my choice. This monitor shows a fair amount more accurate color, gamma and gradation than a typical consumer monitor (including Apple's monitors). This may even be the problem here. The recalibration option is not really an option unless I render my screen useless for photography or color matching purposes.

Looks like this is a bug in the OS that lives at some deeper level than the user configurable settings of MacOS address.

Still looking forward to a solution in Sierra, if any, rather than biting the bullet and seeing if High Sierra solves this. I'd rather not upgrade until 10.13.1 or later, because any earlier tends to pan out as a downgrade.
