mac-os-debloat

Debloat your Mac from the terminal. Zero dependencies. Zero install.

Interactive console util to disable 269 non-essential macOS launchd services. Reclaims ~1.5-2 GB RAM and a chunk of CPU for whatever heavy work you're actually doing. Persistent across reboot. Fully reversible. Built for macOS Tahoe 26.x on Apple Silicon.

No SIP disable required — works with System Integrity Protection fully on, via Apple's supported launchctl disable. That covers ~90-95% of the bloat with zero security tradeoff; squeezing the last few daemons means turning SIP off permanently, which isn't worth it for most people. It also validates every service against your actual system at launch, so it never acts on a label that doesn't exist on your macOS build.

Or via curl:

curl -fsSL https://raw.githubusercontent.com/OleksandrKrupko/mac-os-debloat/main/debloat | python3

Or via Homebrew:

brew install OleksandrKrupko/debloat/debloat && debloat

Commands

Runs the interactive TUI by default. Non-interactive flags for scripting and quick recovery:

debloat                 # interactive TUI (default)
debloat --status        # disabled/enabled counts, spotlight, reclaimable RAM
debloat --audit         # list any embedded labels not present on your macOS build
debloat --disable-all   # disable every non-essential service (prompts sudo)
debloat --enable-all    # re-enable everything — the panic button
debloat --restore       # revert to the state before your last apply
debloat --dry-run       # with --disable-all/--enable-all: preview, apply nothing
debloat --status --json # machine-readable status

--status, --audit, and --dry-run need no sudo — reading launchd state is unprivileged. Every apply first snapshots your current state to ~/.mac-os-debloat/latest.json, so --restore always brings you back. If anything feels off, debloat --enable-all turns it all back on.

[✓] = enabled · [ ] = disabled · * = unsaved change

Uses launchctl disable — writes to /var/db/com.apple.xpc.launchd/disabled.plist.

• Survives reboot
• Wiped by macOS major upgrades (26.3 → 26.4 etc) — re-run after upgrade
• system/ disables affect all users · gui/$UID disables only current user
• Multi-user: run once per account

Drop a labels.txt next to the script — it overrides embedded list.

# === Your section ===
com.apple.something                # what it does, what breaks

These will break the system. Not in default list, but if you add manually:

• com.apple.WindowServer, controlcenter, notificationcenterui, Finder, Dock, SystemUIServer — UI dies
• com.apple.coreaudiod — sound dies
• com.apple.accountsd, syspolicyd, securityd, trustd — auth / codesign break
• com.apple.mds*, corespotlightd — use mdutil -a -i off instead
• com.apple.softwareupdated — kills security updates
• com.apple.XprotectService — kills malware scanning
• com.apple.CoreLocationAgent, searchpartyd — Find My breaks

macOS Tahoe (26.x) baselines at ~4-5 GB RAM and a steady CPU drip from ~50 Apple daemons you mostly don't use — Siri, Apple Intelligence, telemetry, ads, predictions, AirPlay, Photos analysis, etc. On a 16 GB Mac that's a third of your memory gone before any of your own apps start.

This tool kills the ones you don't need, persistently, with a single console util and no install. ~1.5 GB RAM and a few % CPU back for whatever you're actually running — compilers, browsers, VMs, model inference, video editing, games, whatever.

The ~1.5-2 GB figure is the drop in used memory on an idle M4 MacBook Pro 16 GB (macOS 26.3.1) after disabling the full default set and rebooting, compared beforehand. Your number depends on which services you actually run — check debloat --status for the reclaimable RAM on your own machine before and after.
