Just in time for macOS Sierra we have AutoDMG 1.6:

• Added 10.12 support.
• Removed 10.8 support.
• AutoDMG will not try to remount already mounted images, fixing 10.12 installer.
• Added advanced option to skip asr imagescan (thanks @timsutton).
• AutoDMG will not relaunch on login (thanks @nmcspadden).
• Fixed volume size setting not being saved to templates (thanks @timsutton).
• Fixed handling of relative package paths on the command line (thanks @timsutton).
• Fixed usage of base image as source on the command line (thanks @timsutton).

You can download 1.6 from the AutoDMG releases page. If you have questions or need help, you can join us in #autodmg on Slack MacAdmins (but please check the documentation and especially the FAQ first).
