How to free or clear system data on Mac as it takes too much space

To clear system data on Mac, Why not use "Store in iCloud" and "Optimize Storage" are built-in macOS features designed to help manage storage space, but they are more about smart storage management rather than directly clearing system data on Mac.

Store in iCloud: This feature automatically uploads your desktop, documents, and photos to iCloud, freeing up local storage. Files stored in iCloud are removed from your Mac but remain accessible via iCloud, helping reduce local system data.

Optimize Storage: This option automatically removes Apple TV movies and TV shows you've already watched and keeps only recent email attachments. It also stores only optimized versions of your photos and videos locally, with the originals stored in iCloud, thus freeing up space.

While both features are useful for managing storage, they don't directly clear system data like caches, logs, or temporary files. If your goal is to completely clear system data on Mac because it takes too much space, these options can be part of a broader storage management strategy, but for a more thorough cleaning, you'd typically need dedicated tools or manually deleting caches.
