You're not alone. Here's why it happens and what to do: Cause: System files, caches & incomplete iCloud sync can eat up space. Fix: Restart, offload apps, check iCloud settings, update iOS (if needed). Last Resort: Backup & restore as new (erase all content first!).

Hidden system files might be using more space than shown or you might have large files cluttering your Mac. Try this to free up space: Check "Storage" details in "About This Mac." Clean up unused files, Downloads, and media. Optimize storage with built-in macOS tools. Empty Trash securely. Why do you need to experiment with installing a different os at first place?
