We current ship a commercial app. We code sign, notarize, and staple our App We then place it on a DMG using DropDMG, but do not code sign the DMG. We distribute the DMG via our Web site and not the MacApp store.

QA testing on Catalina and Big Sur show only the usual "This (the DMG) has been downloaded from the Internet" warning that your get even with a signed DMG if downloading outside of the MacApp store. Where as a signed DMG will not open on Mavericks and a couple other above 10.9.

We test on 10.9 to 10.16 as that is the range of MacOS versions supported by LC.

To avoid the unidentifiable developer warning in recent macOS versions, you do 
need it signed. If your market is consumers, that is what they will have.

DropDMG is great.

If the App is Signed and Notarized, it is actually best NOT to sign the DMG.
Older versions of MacOS (like Mavericks, etc.) have a problem with signed DMGs
thank you very much, very helpful!

Hi friends,

quick question, now we have a Mac app, signed and notarized
and what not, is it also neccessary for the DMG we create from
that app for distribution?

Thanks for any insight!
Best

Klaus
