I cretaed my app.dmg in BigSur through a script, there I am using "hdiutil create -ov -fs HFS+ -srcfolder .. ". When i try yo install Its giving alert "app.pkg can't be installed because its digital signature is invalid" in OSx 10.10,10.11. But if I remove "-fs HFS+" then DMG is not mounting only in OSx 10.10.
