How to manage storage on MacBook Air M3?


I have a 6-month old MacBook Air M3 with latest MacOS, but is acting very slowly. It may be HDD related.


HDD 245 GB space but usage by to nearly 80%.


System data 58.47 GB

MacOS 29.84 GB

iOS files 33.28 GB

Applications 70.33 GB


191.92 GB


78% used by Mac so only 22% available for my stuff (movies, music, docs).


This can't be right. What do you suggest I do to free up system and MacOS space?


And why is there 33.28 GB of iOS data on my Mac? Can I delete it all?


Thank you.




MacBook Air 15″, macOS 15.3
