Reducing System/Volume/Data is a common question. 

1 - Detailed methods that may or may not work 

A -  System data taking too much in MacOS Sono… - Apple Community

B - Time Machine Local Snapshot won't delete - Apple Community

C - Over 60% storage blocked by System Data - Apple Community

D - Running out of storage - system data is huge after upgrade to macOS Tahoe 26.2

How to free up ‘System Data’ and other storage on your Mac from a fellow colleague  @ neuroanatomist

Use another application to see where space is being used  Storeograph  Directly from the Developer

Suggest getting an External SSD Drive and start moving your Pictures, Videos, Music and any other large files you have control over, OFF the Internal drive and Onto the External

Understanding iCloud Drive from a well written User Tip from @ Richard.Taylor

2. Quick Fix Actions:

 For Apple Silicon computers, use Disk Utility to erase a Mac.

For Apple Intel computers, use Disk Utility to erase an Intel-based Mac, then reinstall macOS.

Always make a Time Machine backup before proceeding.

 Migrate only the user account, not the entire system.

 Reinstall only the necessary applications from the Apple App Store or directly from the developers.

3.- Generally

When the user ( you ) discovers this issue, it’s likely because the computer’s internal drive capacity is small, such as 256 GB or 512 GB.

The user’s storage needs may have increased since the computer was purchased.

To future-proof the computer, consider spending extra money upfront on a larger drive capacity and adding more unified RAM.

Note - On Apple Silicon and newer computers. The SSD Drive and the Unified RAM are Soldered to the Logicboard and can not be upgraded.

With respect to "system data", you can not "get rid of it". Here are some steps to follow to free up storage on your Mac:

It isn't. There's no such thing as "system data". Never was.

with no way to get rid of it?

You may not need to get rid of it.

Are you having a problem of some kind? Please describe the problem in your own words.

Note that anything you see in System Settings > General > Storage is not reliable. Ignore anything you see there. It isn't true. So when I ask you to describe the problem, don't use information from that display.

And how do I get rid of it?

"System Data" is the Apple equivalent of "the aether". It is an odourless, massless component that permeates all things, and also doesn't exist.

Please focus on the problem you are experiencing. I can tell you that this is extremely common. If you are unfortunate enough to have purchased a Mac with a 250 GB hard drive, then you're going to struggle to keep enough free storage to keep the system running. Ideally, you want to keep 100 GB of free storage. Yes. You read that correctly. Any less than that and you will experience various types of degradations of performance and user experience. You can purchase a 3rd party storage management tool and use it regularly to delete/archive files you don't need. (And that are safe to delete from the startup volume!)

I have plenty of Empty Space on the machine

I also have the M4 Mac Mini with the stock 16 GB Unified RAM and the 512 GB SSD Capacity Drive

Both machine are running Tahoe 26.4

Also, plenty of Empty Space

I'm planning on getting a MacBook Air M5 (my dad hoards the desk), and that will have 512 GB, so that will definitely help. thanks!

IMHO, 512GB storage is not enough in today's computing environment. At a minimum get 1TB, more is recommended.

that is 100% out of my budget... even with a trade in, its too much.

plus, this would be mainly my creativity computer (logic pro, final cut, adobe illustrator, etc) while i have a seperate computer for gaming, etc

An upgrade from 512GB to 1TB is approximately $200. I think increased performance, longer useful life, and additional storage is worth the $200. But the choice is yours. You are currently experiencing issues due to insufficient storage, why repeat that experience going forward?
