I want to distribute my application. I successfully sign it with my apple ID, and a profile. codesign -dvv returns Identifier=com.xxxxx.OrchPlay Format=app bundle with Mach-O thin (x86_64) CodeDirectory v=20500 size=1134854 flags=0x10000(runtime) hashes=35455+5 location=embedded Signature size=4755 Authority=Developer ID Application: Baptiste xxxxx (62CS2SG5TM) Authority=Developer ID Certification Authority Authority=Apple Root CA Signed Time=Mar 22, 2021 at 7:46:06 PM Info.plist entries=23 TeamIdentifier=62CS2SG5TM Runtime Version=10.15.0 Sealed Resources version=2 rules=13 files=4 Internal requirements count=1 size=220 So why when i upload it and then downloading on a server do i get the "can’t be opened because Apple cannot check it for malicious software" warning? I have no clue. The system and XCode gives me no warning, and only when opening it i have an issue.
