Adjust width of spacer between Mac OS dock icons Many of you might know that it is possible to add a spacer to the Mac OS dock icons with:

$ defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}'
$ killall Dock


but the problem is, I find them a bit wide by default. I do understand the size of the space is the same as an actual icon but I'm wondering if anyone knows a way to adjust the space of those spacers

An image of the spacers I'm talking about can be found here
I just tried typing in different things and discovered that &quot;small-spacer-tile&quot; adds a narrow space.
defaults write com.apple.dock persistent-apps -array-add '{&quot;tile-type&quot;=&quot;small-spacer-tile&quot;;}'
killall Dock

Here, a &quot;small-spacer-tile&quot; vs a &quot;spacer-tile&quot;:
