Mac OS has a raster PDF tool included. Windows doesn’t.
Meaning that any software on a mac can use the macos included tool to import a PDF as an image only. no vector. without paying any extra fee.
Same idea, Mac OS comes (or at least used to) with more fonts than windows. Stuff like Helvetica. Using a mac and softwares on a mac allows you to use Helvetica.
If you’re working on a PC, you’re supposed to buy it - or work with a software that paid for it (hi adobe)
It’s the wonderful world of licensed stuff.
