You can increase the open file limit using the `ulimit` command. For a temporary increase (current session only), use `ulimit -n `. To make it permanent, you need to edit the `/etc/security/limits.conf` file (requires sudo). Add lines like `* soft nofile ` and `* hard nofile `, replacing `` with a higher value (e.g., 4096 or 8192). Remember to log out and back in for the changes to take effect. On macOS, you might also need to adjust launchd limits.
