Joe, 500 GB SSD, has 167 GB left, so should not bother with all this stuff?
It seems rather pointless at with that much space left
I don't put any data on it. Just mac os stuff.
"DMA sees and analyzes APFS data structures and hidden volumes that DD either does not see or hides. (I wish that was optional and I have contacted DMA developer who has promised to consider my request in the next release.)"
What did that mean, saying feature you wish was not there..?
I am glad the feature to see the system volumes, and snapshots is there, but on my system that means I have a list of 146 volumes only 7 of which I have any control over their contents. The belongs to the OS and is just confusing information clutter or overload. I would like the ability to filter out the system volumes and snapshots.
Caches.. easy one to clean, but would not bother?
The other stuff very draining, containers. application support, etc your vote is just let it be?
Yes and Yes.
Back in the days when disk capacity was in MegaBytes frequent housekeeping was essential. In today's environment where 256 GB drives are the absolute minimum and macOS has gained the intelligence and ability to manage that disk space and even spool seldom used files off to the iCloud Drive it is a different world. If your drive were approaching, say 90% full (many experts now say less than 2 GB available space but that would make me nervous to get that low), then it would be prudent to start taking a hard look at how the space is used and take steps to create more
breathing room. APFS and SSDs play a big part in this as well because unlike HDs, SSDs do not benefit from having the files in consecutive sectors on the drive, and intentionally place the sectors constituting the file in apparent random locations. Routine stuff like defragmentation, optimization and keeping total storage to less than 80% of capacity are a waste of time and effort. I still go through spells of disk space management out of habit more than actual need
By-the-way deleting Application Suport will immediatly break your applications.
