2. DMG Installer Download

If you cannot access the Mac App Store or prefer direct downloads, we provide a DMG installer package.

Note: When installing via DMG, macOS security features might require you to explicitly allow the application in "System Settings > Privacy & Security" the first time you open it.

⚠️ Grant Full Disk Access

ATBCmder is a file management tool and requires explicit disk management permissions from the user. Please follow these steps:

  1. Click the Apple icon in the top-left corner of your screen and select System Settings (or "System Preferences" on older macOS versions).
  2. Navigate to Privacy & Security in the left or right menu.
  3. Scroll down and select Full Disk Access.
  4. Find the application (ATBCmder) in the list and toggle the switch to turn it on. If the application is not in the list, click the + button at the bottom to add it manually.
  5. The system will ask you to enter your Mac login password or use Touch ID to confirm the changes.
