It works for me, so it's going to be difficult to debug. I expect that the problem is somehow related to Qt but this is just a guess.

I can offer two solutions:
a) you wait a bit; I will create a new dmg for 4.2rc2 which is going to use Qt5. Qt5 should have a lot less bugs on macOS.

b) you could disable the pager (which seems not too bad in a GUI environment):

>page_output_immediately(1)
>page_screen_output(0)

This can be conveniently added to you ~/.octaverc.

I am experiencing the same issue. Paging works fine when I run the octave-cli ( /Applications/Octave.app/Contents/Resources/usr/bin/octave-cli ) in a terminal.

I am running 4.0.3 dowloaded from:
https://sourceforge.net/projects/octave/files/Octave%20MacOSX%20Binary/2016-07-11-binary-octave-4.0.3/octave_gui_403_appleblas.dmg/download

While preparing this comment the hung gui got this error (which may or may not be related)

octave-gui[59702:303] modalSession has been exited prematurely - check for a reentrant call to endModalSession:

This problem may be specific to macOS or to which packaging system you used to build and install Octave. Does the pager work correctly if you run octave-cli in a terminal? Did you install a binary package or use a package manager, which one? Adding sschoeps in cc.

Try `ones(100)` in the Command Window.

This will force a "(f)orward (b)ack (q)uit" pager prompt, but none of those keystrokes seem to have any effect.

Keystrokes appear onscreen, but we never get back to a `>> ` prompt.

Closing Octave GUI now is unresponsive, I have to CMD+ALT+ESC -> force-quit.

Pretty sure that this was working a few days back out-of-the-box.
