I'm trying to import a scene into blender using the Mac version of fSPY. I don't see anything in package contents or the download page to import to Blender itself so that I can import fSPY files.
I've tried using the .dmg file, zipping it, zipping the windows file, digging through package contents for a .py file.
Edit: The answer referenced does not help. I am on a Mac, the answers are for Windows and Linux. Zipped .dmg files do not install into the addons folder of Blender. Installing blender addons on a Mac usually requires a .py file that you manually drag over to the addons folder inside of package contents inside the blender application.
