OmniDiskSweeper — which helps you find files on your Mac to delete, so you can free up space on your drive — has been updated to work with recent macOS releases (it now requires macOS 10.12 and up). OmniDiskSweeper is really great at what it does: showing you the files on your drive, in descending order by size, and letting you decide what to do with them. Delete away, but exercise caution: OmniDiskSweeper does not perform any safety checks before deleting files!
OmniDiskSweeper 1.10 introduces “Trash” as the new default behavior, addresses macOS High Sierra compatibility issues, and fixes several bugs.
