Yes, the step it's like you say.
Using the UDRW format the reason is I need modify the app pos in the folder.
And I will run hdiutil convert "$out" -format UDZO -o "$out_o.dmg" to convert dmg format.
Sorry for not explaining clearly.
Yes, I also sign the dmg, and notarized this dmg.
Thanks for your reply!
Yes I'm using finder to copy Application.
High Sierra Version is 10.13.6.
Big Sur Version is 11.2.3.
Here is my test result:
If i create the dmg on Big Sur, It's can work on Big Sur, But can't work on the lower version.
I need create the dmg on the High Sierra, This way can work on Big Sur and High Sierra.
Here is command i use to create dmg.
hdiutil create -volname $title -srcfolder $workspace -ov -format UDRW $out
