M1 MBA - 256GB version - lots of storage used but it's not me using it...

Seems my M1 MBA has a lot stored in the 'system date', all 66GB of it...

Can anyone explain what this might be and how I'm able to reduce it?

My iTunes is on an external HDD, I've no large files and no films/music stored to the MBA etc...

So what's taking up 66GB?!

Cheers

If you install OS upgrades, things like Xcode, there tends to be a lot of ‘purgeable’ items that hang around, theres about 30 gb of that stuff on my disk last I looked. I think there’s a purge button somewhere.

I have an M1 MBA/Big Sur, and for what it's worth, System Data is a bit over 15gb, so 66 is rather high

Thanks; haven't seen that!

Any suggestions...
