[Serious Help] Uploading Photos on Wordpress With Selenium

I am dead figuring out a way to do this on mac. I tried everything but can't figure out a way to do that. If you know the code, please mention it. I tried the .send_keys method but it doesn't work. I tried the action chain to press Command+Shift+G to open the Go To file prompt on my Mac so I can send the path and open the file but no luck.

Please help me buddies!
