Is it possible to check a code signature of another application bundle on Objective C? Our app has Auto Update function. We need to check the downloaded APP bundle from a ZIP to make sure that it's our application (valid signature and our name in the signature) before run it.

I compiled a dynamic library for macOS (open source) When I checked with otool -L abc.dylib it shows that it links several other libraries from /usr/lib/ Is it OK, or Apple may remove these libraries in future versions of macOS? /usr/lib/libz.1.dylib /usr/lib/libiconv.2.dylib /usr/lib/libSystem.B.dylib /usr/lib/libbz2.1.0.dylib /usr/lib/libobjc.A.dylib

When I check notarization on Mac Mini with M1 chip: bash-3.2$ spctl -a -t exec -vvv '/Applications/My.app' It shows many useless warnings in output.

Hi, I have a problem with replacing altool to notarytool to notarize my app for distribution outside AppStore. Earlier I used this code (-p passes App's password): xcrun altool --notarize-app --primary-bundle-id "MyProductBundleID" -u "myname@gmail.com" -p "wxxx-xxxx-xxxx-xxxx" --file MyProduct.zip I wrote a new script: xcrun notarytool submit MyProduct.zip --keychain-profile "wxxx-xxxx-xxxx-xxxx" --wait Error with unknown "--keychain-profile".

Hi, I distribute my app for macOS outside AppStore. I implemented Auto Update function which worked perfectly up to Ventura 13.0. And it was broken since Ventura 13.1+ The old version of my app downloads a ZIP arhive with a new version to temporary folder and unpack it to User's Library > Application Support > My AppFolder. The new unpacked version gets attribute com.apple.quarantine and the old app cannot run it. Before Ventura 13.1 the new unpacked app could be run successfully and it closes the old version and replaces the old APP bundle in Applications. And then a copy of new app in a temporary folder is being deleted. In fact, the new APP could work as an agent to perform the update of my app. Both apps (old and new) are signed and notarized by one team (the same signature).
