Can anyone help me please?

Start by reproducing the failure from mac_start.command and inspect quickstart.py line 24, then follow the Firefox session setup in instapy/browser.py line 114. Compare the installed environment with the reported Python 3.7, Firefox, and Selenium setup. Done means identifying the cause of the unmatched capabilities error and confirming that the startup command creates a session successfully.
