How to reduce growing System Data on MacBook Air?
"System Data" on my MacBook Air (13 inch, M3, 2024) continues to grow; it's just surpassed 300GB. Is there any way to reduce its size? (I've tried starting in safe mode, to no avail.)

3.- Generally
When the user 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.
