How to Add Terms, Privacy Policy, and EULA to Your DMG Installer (macOS Guide)

DMGKit allows you to display legal agreements—such as Terms and Conditions, Privacy Policy, and End-User License Agreement (EULA), before users can access your macOS installer.

This feature is essential for:

  • Legal compliance;
  • Software licensing protection;
  • Professional and trusted app distribution.


What is SLA Injection in macOS Installers?

SLA (Software License Agreement) injection is a macOS feature that displays a license agreement window before a disk image (.dmg) opens.

When enabled in DMGKit:

  • A license agreement window appears before mounting the DMG;
  • Users must accept the agreement before accessing your app.

Important Limitation (macOS Behavior)

macOS only supports one SLA window per DMG.

To solve this, DMGKit intelligently combines:

  • Terms & Conditions;
  • Privacy Policy;
  • End-User License Agreement (EULA);

into a single unified agreement flow, ensuring all required legal content is presented seamlessly.

How to Enable Legal Agreements in DMGKit

Follow these steps:

  1. Open Settings;
  2. Navigate to Legal;
  3. Enable the desired agreements:
    • Terms & Conditions
    • Privacy Policy
    • EULA

Once enabled, the SLA screen will be automatically injected into your exported DMG installer.

How to Edit Legal Documents

To customize your legal content:

  • Click the arrow button next to any enabled document;
  • The built-in editor will open.

Editor Features:

  • Rich text formatting (bold, lists, alignment);
  • Multi-language support;
  • Built-in automatic translation tools.

Localization (Multi-Language Support)

DMGKit automatically adapts to the user’s system language:

  • If a matching localization exists → it is displayed;
  • If not → DMGKit falls back to the default English version.

This ensures your installer remains accessible worldwide without breaking compatibility.

Best Practices for Legal Agreements

To maximize effectiveness and reliability:

  • Always include Terms & Conditions and EULA;
  • Keep legal language clear and readable;
  • Carefully review all translations manually.

Note on Translations

DMGKit uses on-device processing powered by Apple frameworks (Translation and Natural Language).

While highly accurate, minor wording inconsistencies may occur. Always verify translations before distribution.
