LighterMac Reviews and Details

LighterMac is a native Mac app for the moment your disk is full and Storage settings can only tell you "System Data".

It opens that grey bar into named items — Xcode build folders, package caches, browser caches, old iPhone backups, Docker's disk, app leftovers — and puts one line next to each on what happens if it goes: "Xcode rebuilds it on the next build", "sites load a little slower once, and you stay signed in".

How it differs from a typical Mac cleaner

• It explains before you delete. Every suggestion says what the item is and what removing it costs.
• It only suggests what rebuilds itself. Deletion works from an allowlist of 30 known kinds of storage. Photos, documents and apps are never suggested.
• Trash first, always. Everything goes to the Trash with a list, so any of it can be put back. Automatic rules can only ever use the Trash.
• It measures what you actually got back. Moving something to the Trash on the same disk frees nothing until it's emptied, so LighterMac counts free space before and after.
• Nothing leaves your Mac. No account, no analytics in the app. Its only network requests are licence activation (Pro) and a daily version check.

Also included

• Uninstall apps together with the containers, caches and support files they left behind.
• Move rarely used folders to another drive, leaving a link so nothing that uses them breaks.
• A treemap of what is using space, biggest files, and photos by date.
