Find the largest files on your Mac
To list the biggest files on a Mac, run find with a size limit in Terminal and sort the result. Pick what to search below and copy the command. It only lists files; it never deletes anything.
find ~ -xdev -type f -size +500M -print0 2>/dev/null | xargs -0 du -h 2>/dev/null | sort -rh | head -50
See every big file on a map
Tidy Mac’s Space Map shows any folder as a treemap or sunburst, sized the way APFS really stores it; click to go deeper. Find lists large files and duplicates, or search in plain English. $9.99 once, 2 Macs.
How it works
-xdevstays on one disk, so external drives and network shares aren’t searched.-size +500Mkeeps files over the size you chose (M = MiB).-mtime +90(optional) keeps files not changed for that many days.du -h | sort -rh | head -50prints sizes and shows the 50 biggest first.
Big files are only part of the story: most “missing” space is in System Data, which is many small files. See how to find large files on Mac and what System Data is.
Questions
How do I find large files on my Mac?
In Finder, press Command-F, choose Kind › Other › File Size, and set “is greater than” 1 GB. In Terminal, the command this tool builds lists the biggest files first. macOS Storage settings › Documents also lists large files.
Does this command delete anything?
No. It only lists files and their sizes. Review the list and delete what you don’t need yourself, ideally by moving it to the Trash in Finder.
Why does Terminal say “Operation not permitted”?
macOS protects some folders (Mail, Messages, Safari). Give Terminal Full Disk Access in System Settings › Privacy & Security, or ignore those lines; the command hides them.
Why don’t the sizes match Finder?
du -h shows binary units (1G = 1,073,741,824 bytes); Finder shows decimal GB. Use the GB to GiB converter.
