Hi @quiec!

The script has run into the open file limit set by your operating system. MacOS sets the limit to 1024 by default. You can raise it using ulimit -n 4096 in Terminal. That should be sufficient.

We plan to investigate if this limit can be raised automatically to avoid the confusion that can be caused for those unfamiliar with this OS limit.
