Other in Manage Storage: what is it and how to reduce it?

To repeat what Apple has said is the Final Word on managing the " Other " Category.

• Other: Contains files that don’t fall into the categories listed here. This category primarily includes files and data used by the system, such as log files, caches, VM files, and other runtime system resources. Also included are temporary files, fonts, app support files, and plug-ins. You can't manage the contents of this category. The contents are managed by macOS, and the category varies in size depending on the current state of your Mac.

One is guessing the issue is Really the Capacity of the Internal drive and might be the tiny 128 GB SSD. Though sold by Apple and IMHO should have started with 256 GB - sorry to say, it is what it is !!

Rebuild the Spotlight index on your Mac do this first and then check again. The numbers may change for the better.
