Question 1

How to skip code signing when using create-dmg?

Accepted Answer

Use the --no-code-sign flag to bypass code signing, which is useful in CI environments or if you lack a developer certificate. This prevents exit code failures and still creates a functional DMG, as mentioned in the README options.

Question 2

Does create-dmg support custom backgrounds or icons?

Accepted Answer

No, create-dmg is opinionated and uses its own design defaults without customization options. The README emphasizes simplicity over visual tweaks, so you're limited to the built-in professional look.

Question 3

create-dmg vs DropDMG: which should I use?

Accepted Answer

create-dmg is a free, CLI-based tool focused on automation and simplicity, while DropDMG is a paid GUI with more customization. Choose create-dmg for quick, scriptable DMGs, and DropDMG if you need detailed design control.

Question 4

How to add a software license agreement to my DMG with create-dmg?

Accepted Answer

Place a license.txt or license.rtf file in the current working directory before running create-dmg. The tool automatically includes it as a software license agreement, requiring users to agree before mounting the image.

Question 5

Can I use create-dmg in a CI/CD pipeline?

Accepted Answer

Yes, it's designed for automation with CLI commands and flags like --no-code-sign to handle environments without certificates. This makes it suitable for integration into continuous integration scripts for app releases.

Question 6

What happens if code signing fails in create-dmg?

Accepted Answer

The DMG is still created and functional even if code signing fails, such as without a developer certificate. You can use --no-code-sign to skip signing entirely and avoid errors, as noted in the README's usage examples.
