App is signed, notarized and stapled, I send that dmg file with file transfer tool, it can open correctly on other mac without any warning or error. However, if I send that dmg file through IM to the same mac, it will produces the "cannot check it for malicious software" error.
I check the transfered dmg with spctl -a -t open -vvv --context context:primary-signature MyApp.dmg, it show source=Notarized Developer ID; origin=***
How can I resolve this issue?
