So I recently upgraded from from 10.x.x to 10.3.3 (don't remember which exact version I had before). Everything is fine, but one thing caught my attention. Before the update, I had 3 gigs of free storage. After, I suddenly have 34.8 gigs of free storage.
How is that possible? Is it just the update cleaning the device from all useless pieces of data (installation data/etc, I used to install and reinstall plenty of apps) or is it some APFS magic?
I personally believe that's a little bit of both.
