# Installation problem on macOSMojave

Hi,

I tried to install cadabra 2.2.9 on macOSMojave.

The installation seems to work fine but I obtain the following error upon using cadabra2-gtk:

libc++abi.dylib: terminating with uncaught exception of type std::logic_error: Failed to create table runs libc++abi.dylib: terminating with uncaught exception of type std::logic_error: Failed to read port from server. Abort trap: 6

On the contrary, using cadabra2 does not produce errors.

Thank you for already for any information!

What happens if you try to run cadabra-server ? It should produce some output and then sit there until you kill it, but it probably produces an error instead.

Hi Kasper, Running cadabra-server produces: libc++abi.dylib: terminating with uncaught exception of type std::logic_error: Failed to create table runs Abort trap: 6

Does brew doctor produce anything useful?

I have tried with a relatively clean Mojave machine, and that worked fine. You may want to try to uninstall cadabra2, then nuke anything you can find related to cadabra2, and re-install.
