So I took a screenshot in Minecraft and am searching the Internet from corner to corner and everyone is saying to look in "Library"… The only thing is that I don't HAVE a "Library" (see 
)
So where do I find my screenshots? Things like these really fustrate me.
Okay,
Go to your desktop, click go on the top bar, and then while go is clicked hold the options key. The library should appear.
Then click on it, cilck application support, click minecraft, and then click screenshots.
If your too lazy, next time instead just press command + shift + 3 and that will take a screenshot of your entire screen and save it on your desktop.
Have fun screenshotting
