Famously Gates thought that the Mac cursor may have been a sprite, when it was actually in software https://www.folklore.org/Shut_Up.html

Apple loved doing things in software, ever since Woz wrote the Apple II disk routines in software so their floppy drives didn't need their own controller (the Commodore machines had a whole second CPU running an operating system in theirs). This is also why the one thing that WOULD lag the cursor on a classic Mac was formatting a floppy disk, since it required interrupt-level timing.

Even to this day Apple loves running things in software - the speakers on modern Mac laptops are driven in software - macOS has a daemon that runs and adjusts the speaker volume, tracking the sound pressure sent to them to keep them from being blown out. When Asahi Linux added speaker support, they had to reimplement this from scratch.
