This question already has an answer here:

well the issue is that I use to have ~20gb free in my disk, after updating and removing around 30gb a lot of things, I still have 20gb free in the disk and still says it only has ~20gb free in reality it has over "70gb" free...

Is there a way to remove all that purgeable storage to make my disk free for real?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • 20 + 30 = 50. Where are you getting 70? – tubedogg Oct 5 '16 at 18:32
  • @tubedogg where my math went.... – jycr753 Oct 5 '16 at 18:37
  • Your screen capture shows 76 GB free. What gives you the different information that you still have only 20 GB free? – dan Oct 5 '16 at 20:22
  • @fsb: yes it is the same question, but the accepted answer isn't... good enough. – dan Oct 5 '16 at 20:34

Have you tried Disk Inventory X ? It shows graphically where your space is being used and can help in cleaning up. I use it a lot.

  • That is wrong, being able to have a graphical interface doesnt mean it knows what files apple does consider deletable. In the other hand if you start deleting files you end up with a lot disk errors because that app do not remove the pointer to the files – jycr753 Oct 5 '16 at 19:43
