FileSystemEventHandler on MAC OS not working anymore

[rburchDev]

The below script was working previously on my Mac. Now the on_created event handler never fires. This same script works on my Ubuntu machine.

try:
    base_path = os.environ['EVOLVE_HOME']
except KeyError:
    print('Could not get environment variable "base_path". This is needed for the tests!"')
    raise

def ram_recorder():  # Thread to extract new data from RAM text files into CSV file with timestamp
    class RAMHandler(FileSystemEventHandler):  # Watchdog folder monitor Class
        def on_created(self, event):  # When file is created in monitored folder
            global client  # Call global variables set outside of Class
            new_ram = str(event.src_path)  # Extract filepath from new file in monitored folder
            time.sleep(.5)
            line = linecache.getline(new_ram, 3)
            r_base = os.path.basename(new_ram)  # Strip filepath too base file name
            r_nano = int(r_base.strip('RAM_ .txt'))  # Strip nanosecond time from file name
            if "MemAvailable" in line:
                mem = int(line.strip("MemAvailable: \n kB"))
                body = [
                    {
                        "measurement": "Evolve",
                        "tags": {
                            "Software": version,
                        },
                        "time": r_nano,
                        "fields": {
                            "RAM": mem,
                        }
                    }
                ]
                client.write_points(body)
                return r_nano

    r_observer = Observer()
    r_event_handler = RAMHandler()
    r_observer.schedule(r_event_handler, path=os.path.join(base_path, 'test'), recursive=False)  # Folder to monitor
    r_observer.start()

I am running the following:

• Python 3.9
• Mac OS 11.0.1
• Watchdog 0.10.4

Thanks! I figured, but wanted confirmation
