Does Mac X11 have the XTEST extension?

Question

So I moved some X programs down to the mac, and I'm getting

Error: XTEST extension unavailable on '(null)'.

from xdotool.

• Does OS X X11 come with XTEST?

• If not, is there a way to add it?

Answer 1

Run the following command in the Terminal:

defaults write org.x.X11 enable_test_extensions -boolean true

(as per here). Then quit and restart the X server; the XTEST extension should then be available.

Answer 2

I had to do the following two commands to get this to work on Mountain Lion (from here):

defaults write org.x.X11 enable_test_extensions -boolean true
defaults write org.macosforge.xquartz.X11 enable_test_extensions -boolean true

Answer 3

For XQuartz,

defaults write org.macosforge.xquartz.X11 enable_test_extensions -bool yes
