Core Setup Guide
Permissions
ZaynCleaner asks for as little as possible. Here's what each permission is for, and how to grant it.
Full Disk Access (recommended)
macOS hides some cache and log folders from apps unless they have Full Disk Access. Without it, ZaynCleaner still works, but it can't measure or clean those folders, so the totals are lower than they really are.
1
Open the privacy settings
Open System Settings → Privacy & Security → Full Disk Access.
2
Add ZaynCleaner
Click +, choose ZaynCleaner from Applications, and turn the switch on.
3
Reopen the app
Quit and reopen ZaynCleaner. Run Doctor (in the logo menu) shows whether access is granted.
Administrator password
Some optimizations change system settings and need admin rights. ZaynCleaner never asks for your password itself: these tasks open in Terminal, where macOS asks you directly. You can enable Touch ID for these prompts from the Optimize page.
Automation (Finder and System Events)
Emptying the Trash and listing login items use AppleScript, so macOS may ask once whether ZaynCleaner may control Finder or System Events.
No other access
No camera, microphone, contacts or location. Scans and file lists never leave your Mac.
