Fix for installer failing on ARM mac mini sonoma 14.4.1

[latortuga71]

Hello i wanted to submit this fix for the post install script. On my new mac mini i was not able to successfully run the installer due to the /usr/local/bin directory not existing. Here are the logs from my failed install. Hopefully this can help.
