问题
I was alarmed when I checked the amount of storage my "System" files took up on my Mac:
So I went into /Users/[User]/Library/Android and saw that my SDK took up 150+ GB of space! So I got the info of all the files inside of the SDK but saw that they clearly do not add up to 152.64 GB. Then I used Cmd+Shift+Dot(.) to show all of my hidden files and saw that this .temp directory took up 91.89 GB of space. So my question is, what is it for?
回答1:
I have found the answer: Turns out the .temp folder just stores past SDK Manager download/update operations: Check this Stack Overflow Post
So I just deleted it and freed 90 GB of space.
(Turns out I had a huge amount of failed installations.)

You should probably check out the system-images directory and uninstall what you don't need.
