Safety

mac-cleaner is designed to protect your system:

• SIP-protected paths are blocked — /System, /usr, /bin, /sbin are never touched (/usr/local is allowed)
• Swap/VM protection — /private/var/vm is always blocked to prevent kernel panics
• Symlink resolution — all paths are resolved before deletion to prevent escaping intended directories
• Three-tier risk levels — every category is classified as safe, moderate, or risky so you know what you're getting into
• Re-validation before deletion — safety checks run again at deletion time, not just during scanning
• Dry-run mode — preview everything before committing with --dry-run
• Interactive confirmation — explicit user approval required before anything is deleted (unless --force is used)

Installation

Homebrew

brew install sp3esu/tap/mac-cleaner

Build from source

Prerequisites: Go 1.25+, macOS

git clone https://github.com/sp3esu/mac-cleaner.git
cd mac-cleaner
go build -o mac-cleaner .
./mac-cleaner --help

Shell Completion

Generate shell completion scripts for tab-completing flags and subcommands.

Bash:

# Load in current session:
source <(mac-cleaner completion bash)

# Install permanently:
mac-cleaner completion bash > /usr/local/etc/bash_completion.d/mac-cleaner

Zsh:

mac-cleaner completion zsh > "${fpath[1]}/_mac-cleaner"
# Then restart your shell or run: compinit

Fish:

mac-cleaner completion fish > ~/.config/fish/completions/mac-cleaner.fish

PowerShell:

mac-cleaner completion powershell | Out-String | Invoke-Expression

Usage

Interactive mode (default — walks you through each category):

./mac-cleaner

Scan everything, preview only:

./mac-cleaner --all --dry-run

Clean system caches without confirmation:

./mac-cleaner --system-caches --force

Scan everything, JSON output:

./mac-cleaner --all --json

Scan all but skip Docker and iOS backups:

./mac-cleaner --all --skip-docker --skip-ios-backups
