Here's how to bring back more transparency in macOS 27

[pdfu]

If you were a fan of Liquid Glass in macOS 26, you may have missed the more transparent design of titlebars in macOS Tahoe.

While the exact same design is no longer possible because macOS 27 removed the previous rendering pipeline, you can get pretty close.

Softer scroll edge effect​

For a softer scroll edge effect background, run:

defaults write -g MPV8 -bool false

Now any app you open that adopts the default scroll edge design will respect your change. You'll need to restart apps to see the effect, or reboot your Mac.

Remove with:

defaults delete -g MPV8

Transparent look​

For an even more transparent look, you can disable the scroll edge effect completely:

defaults write -g NSScrollPocketEnabled -bool false

You'll need to restart apps to see the effect, or reboot your Mac.

Remove with:

defaults delete -g NSScrollPocketEnabled

App-specific overrides​

If you don't want the same effect on every app, you can add local overrides:

defaults write com.apple.mail NSScrollPocketEnabled -bool false

And remove:

defaults delete com.apple.mail NSScrollPocketEnabled

Enjoy!

Was kind of hoping this would work on Tahoe to get the new GG design (by enabling MPV8), but doesn't look like it. Oh well.
