Alfred transparency issues, MacOS 10.14

Recommended Posts

Hello! I'm having some transparency issues (there is no transparency) on MacOS 10.14, Alfred v3.7 [938].


I removed and reinstalled Alfred, to no avail. The transparency issues exist at a clean install, before I sync my settings folder.

Hi, I had the same problem.

I don't know exactly when my Alfred lost transparency, but it must be related to some of my preference changes.

After changing to a new created macOS user account, I open Alfred and found the transparency is normal.

Can Alfred team locate the problem and fix it? Maybe I need to change to a new macOS user to make my Alfred appearance normal.

Thanks to @niceSprite for the pointer. I was able to recreate a new macOS account having transparency, so I started going through my list of customizations on my main account. 


It was a defaults issue with the key "NSRequiresAquaSystemAppearance".


When I upgraded to Mojave, I lost the option to have a dark menu bar with light windows. I tried dark mode and didn't love it, and followed this article to get back my pre-Mojave menu bar color: https://www.tekrevue.com/tip/only-dark-menu-bar-dock-mojave/


So I did 

defaults write -g NSRequiresAquaSystemAppearance -bool Yes

It wasn't perfect, so I reverted back with 

defaults write -g NSRequiresAquaSystemAppearance -bool No

That caused the issue. I re-read the article and found I should have deleted the key entirely. So I gave this a go: 

defaults delete -g NSRequiresAquaSystemAppearance

After logging out and logging back in, transparency was back in Alfred. I don't know what this actually did that messed with Alfred's transparency specifically, but this was a resolution for me. Hopefully it will work for @niceSprite as well and we can call this resolved.

Thank you for saving my time! I did change this preference for get dark menu bar in light mode. Then I decided to use default, but the article guided me use command

defaults write -g NSRequiresAquaSystemAppearance -bool No

to undo the preference, and thus cause the problem.
