Here is a better step by step.
Alrighty! I found it! On my MacBook, I found it through desktop, Go, clicking Computer, then Macintosh, Library and then that shows all the folders.
Now I'm trying to find Godot. I think it's because I don't originally have godot on my laptop. And I transferred PNGTuber Plus to my applications folder.
Now... I think I'm stuck.
(Edit): Do I download godot on my computer to bypass this? Or is there another way to do it? Because... uh... I looked everywhere within those files and found nothing.
(Edited a day later): Here's what I see when I go into Application Support
Huh... that's really weird. I looked there more than once and I still couldn't find it.I did place it into the Applications Folder, and still nothing. I'll look again though and keep trying to find it or loopholes. I'll edit this reply if I find something or not.
Thank you so much again for helping me.
(Edited a few minutes later): Still nothing after checking. I think the only thing I can do is to wait for an update for the Mac version so I can upload all my files... I truly appreciate you helping me out though, and I know how to get to most of it and I'll keep all of what you said in mind.
