Error when training Quickstart dialogue model

Hi people, I installed rasa_core on my mac (mid 2010), OSX( 10.13.6) and I’m getting the following error:

1] 14984 illegal hardware instruction ./.dev-env/bin/python -m rasa_core.train -d domain.yml -s ./data/stories.md -

Hardware configuration is as follows: MacBook (13-inch, Mid 2010) Processor 2,4 Ghz intel core 2 dua Memory %GB 1067 MhZ DDR3 Graphics NVIDIA GeForce 320M 256MB

How much RAM is that? there’s a % sign instead of a number there
