macOS Disk Usage Analysis
I always seem to be running out of storage space on my MacBook.
I found the default storage analysis tools provided by Apple to be rather underwhelming and basic in comparison to my experience using Ubuntu Linux.
I felt that Baobab and GParted were much more powerful tools.
Unfortunately, GParted is not available for macOS.

The solution with a GUI that I found to be useful is a program called Disk Inventory X.
It is open source, as described here:
It is absolutely free and released under the GPL. The layout algorithm is based on KDirStat. The idea to develop this program came to me when a fellow of mine showed me his creation WinDirStat.\
It can be downloaded here:

Thank you for this software, Tjark Derlien.
