MacOS – disk space not being reclaimed

disk-spacefinderhard drivemacos

When I first log in to my mac, the bottom of the finder window shows 28.7 GB available

As soon as I interact with the finder, that changes to 417.35 GB available

However, in the terminal df shows:

Omnisweeper shows 28.7 GB free, 720.6 GB used, 751.1 GB total

When I am working with certain applications in the terminal, I get errors/warnings about disk space being too low…

I tried booting into safe mode, and the progress bar got to 95% and sat there for… 20 minutes.. I eventually gave up trying to boot into safe mode.

Is there anything I can do to solve this other than formatting my drive and starting over?

I am running Mojave 10.14.3 (18D109) on a mac pro Retina, 13-inch, Late 2012.

My solution was to create a 415GB file and then delete it. Now everything is working fine.
