Map of data usage?

[TwoLaneHighway]

I have a rMBP with macOS Sierra on it, and am wondering if there is a way to get some sort of a visual map of how my hard-drive is being used?

On my 1 TB SSD, I only have 29GB left, and it would be helpful to see where all of that storage have gotten used up.

Also, maybe some of my storage is being used by things that don't matter to me (e.g. iTunes, caches files, etc) and if I knew more about them, I could free up some space.

I am looking to install a 2TB SSD on my other rMBP and install Big Sur, but that will take me weeks to get it built and all of my software installed and configured and hpefully working, and in the mean time it would help to know that my older rMBP won't run out of space as I start to build a new machine.

I use DaisyDisk for this. They should have a free trial will show you where all the data is.

Is it safe to use?

I’ve used it for years. The trial is incapable of deleting anything. Just check their site to see how it works.

I have always used WhatSize, which has always worked well for me.

I thought there was common software that does what I mention in my OP that was considered "spyware".

Maybe it was Omni Disk Sweeper?
