What is a free alternative to something like Daisy Disk, for finding out what is hogging your MacBook hard drive? I suddenly lost a bunch of hard drive space...Has anyone had good success with a FREE Daisy Disk alternative that graphically shows the disk usage that you can recommend? Thx.
For years I have used OmniDiskSweeper.

It is free, and shows your files in a column view, sorted by size. It’s very easy to use and fast (well, as fast as your HD or SSD allows :-)
