Try this for mac

⇧⌘3 takes a screenshot of whatever you're looking at. This is part of Mac OS and works regardless of what application you're running. These screenshots are saved on your desktop and are pixel perfect (lossless PNG).

Pressing F13 while in Subnautica, and see if that do anything. It might save the screenshots in a game folder.
