1 purchase covers your laptop, desktop, and work machine.

When you receive macOS "Disk Almost Full" warnings, clicking into System Settings reveals a frustrating "System Data" block taking up 80 GB with zero explanation. Typical cleaner utilities bombard you with scary alerts, demand $39/year subscriptions, and risk deleting essential operating system cache files, while raw terminal commands like du or cryptic treemaps feel hostile and confusing.
12 GB remaining on a 512 GB SSD, with 110 GB swallowed by anonymous "System Data" and forgotten client video exports.
Ghost Files surfaces 48 GB of forgotten installers, abandoned caches, and old screen recordings, safely revealed in Finder and cleared.

Answer “What's eating the space on my Mac?” in seconds with zero fearware or daemons.
Why a focused Usefulware utility is dramatically superior to default OS tools or multi-gigabyte bloatware.
System Settings is non-actionable; complex treemap tools are visual sensory overload; and subscription cleaners run battery-draining background daemons while demanding $39/year.
GhostGB provides 4 calm, intuitive lenses (Ghost Files, Space Map, Category, Top Monsters) that reveal forgotten gigabytes in seconds, without background processes, daemons, or recurring fees.
Clear boundaries between sibling utilities so you always select the exact right tool for the job.
GhostGB uncovers broad storage hogs, forgotten large files untouched for months, and developer caches across your Mac. CopyScout finds byte-for-byte identical duplicate copies of files to delete.
Choose GhostGB when your Mac disk is full and you need to understand what categories, folders, or forgotten monster files are eating your storage.
Choose CopyScout when you suspect you have redundant copies of the same photo, video, or document scattered across drives.
