Quick Start Guide

Getting Started with ZaynCleaner

Everything you need to install ZaynCleaner and free up your first gigabytes. Nothing else to install: the cleaning engine is bundled inside the app.

Review before anything is removed

Every scan ends with a list you can check item by item. Nothing is cleaned until you press Permanently clean, and uninstalls and Analyze deletions go to the Trash.

Setup in 4 Easy Steps

Download ZaynCleaner

Download the disk image, open it and drag ZaynCleaner onto the Applications folder.

Download for macOS

Open it the first time

This early build isn't notarized by Apple yet, so macOS blocks it the first time. Go to System Settings → Privacy & Security and choose Open Anyway. After that it opens normally.

Grant Full Disk Access (recommended)

macOS hides some cache and log folders unless an app has Full Disk Access. ZaynCleaner works without it, but measures more with it.

Permissions guide

Scan, review and clean

Press Scan. A planet spins while ZaynCleaner measures caches, leftovers and large folders. Untick anything you want to keep, then press Permanently clean.

What each section does

Clean

Press Scan. ZaynCleaner looks through app caches and logs, developer tools, AI tools, system data and the Trash. Expand a category to see every item, untick what you want to keep, then press Permanently clean. Manage Separately lists large folders such as VMs, Docker, simulators and backups, for size only.

Apps

Uninstall removes an app with its caches, preferences and support files, and the app goes to the Trash. Updates lists outdated Homebrew apps. Startup turns login items and launch agents on or off.

Optimize

A short diagnosis of your Mac and the optimizations it would apply. Press Optimize to run them; tasks that need admin rights open in Terminal so you can see and approve them.

Analyze

A treemap of your disk. Folders appear instantly and sizes keep growing while the scan finishes in the background. Click to drill in; right-click for Copy Path, Reveal in Finder or Move to Trash.

Status

Live health score, CPU, GPU, memory, battery, disk, network and thermals, with a sortable process list.

The logo menu

Keep Screen On, Clean Screen, Network & Speed Test, AI Tool Cleanup, Run Doctor, Settings, Check for Updates and About.

Admin tasks happen where you can see them

ZaynCleaner never asks for your password itself. Tasks that need administrator rights open in a visible Terminal window, where macOS asks you directly, or Touch ID if you enabled it.
