nearly 1/2 TB of system files???

[guido.coza]

I have a mb pro 15" retina with a upgraded 1TB ssd. Sadly this does not help me much as system takes nearly half that space up already I have virtually nothing stored on the mashine and only have 39odd GB space available.
Any ideas whats happening? There is 14odd gig purgable but still 460GIG system files???

This is proabably more of a MacOS post than iOS 14 ?

Your Screen Shot shows - system 459 g - that is a alot - could be back ups of other iOS devices buried in the Library Folder? iPads, Iphones?

Have you tried the apple menu - About this mac < Storage (Tab) < Manage (Button) < Reduce Clutter / Review Flies?

Might help to post what macOS you are using ?

1TB is a lot of storage

View your system disk in the Finder (select "Go to Folder..." in the Go menu of the Finder and enter / )
Click on the "Size" column to sort by size in descending order.
Select "Show View Options" in the View menu.
Check "Calculate all sizes"
It will take awhile to calculate all the sizes. It might help to select "Get info" for a folder that hasn't finished calculating yet, or open the folder and Get Info on the contents.
Once the calculating is done, you can start going through the folders that are the largest to get a sense of what is taking all the space.
