I recently downloaded the macOS Catalina beta. However, it messed up a lot of my daily apps, so I decided to downgrade back to macOS Mojave. I did the following:
Backed up everything
Shut down Mac
Turn it on while pressing Command + Option + R until a spinning globe appeared
Selected "Reinstall macOS"
Waited until it finished
Opened Disk Utility
Removed past partition (macOS Catalina one)
Checked how much free space I had and found this:
It says that I currently have 104.73 GB available of 499.96 GB! And almost 400GB are being used by the system!
How can I get my space back? Where should I start looking?
When I click on "Manage" (Administrar...) this is what my system shows:
I'm using a 13" 2016 MacBook Pro with Touch Bar with macOS Mojave 10.14.5 (18F132).
