FastCopy for Mac: the fastest ways to copy files on macOS

Finder: fix the defaults first

Finder copies sequentially and quietly caps throughput on network shares. Two things help immediately: disable "Copy items as symbolic links" style oddities by keeping default settings, and for big jobs use the built-in Archive Utility (compress → move → extract), which often measures faster than plain drag-and-drop for many small files.

rsync: the closest thing to FastCopy

macOS ships rsync. rsync -ah --progress --stats source/ dest/ gives you diff-mode behavior (only changed files copied); add --delete for FastCopy sync-style mirroring. For verification, --checksum compares file contents rather than timestamps — the closest analog to FastCopy Verify.

When you want a GUI: dedicated tools

Carbon Copy Cloner and SuperDuper! handle scheduled mirror backups with verification. For drag-and-drop speed improvements, mosCourtesy-style utilities exist but the honest answer is: rsync + a wrapper script covers most FastCopy-class needs on a Mac.

FastCopy is Windows-only — here is what to use elsewhere

• rsync (built-in) — Diff copying, mirroring with --delete, checksum verification
• Carbon Copy Cloner — Scheduled, verified mirror backups with a GUI
• SuperDuper! — Simple, reliable full-disk clones and scheduled backups

Since FastCopy is Windows-only, these macOS tools are the practical substitutes — test rsync first, it is free and already installed.
