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

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.

When I notarize two apps the same time I get wrong DMG image for second app. I use a command for App1 and then for App2: xcrun altool --notarize-app --primary-bundle-id app1id -u my@email.com -p xxxxxxx --file App1.dmg xcrun altool --notarize-app --primary-bundle-id app2id -u my@email.com -p xxxxxxx --file App2.dmg Then I get an email with a successful notarization, I call xcrun stapler staple App1.dmg xcrun stapler staple App2.dmg DMG with App1 is correct. Signed and notarized. But after stapling DMG with App2 is wrong - it includes App2 and App1 (!) and DMG has increased file size! Of course, I've sent for a notarization only a single App2 in a DMG. What I'm doing wrong? This problem doesn't appear if I send App2 for notarization AFTER successful notarization of App1 and stapling DMG image. macOS 11.1 Big Sur, Apple DTK.

Is it possible to find deprecated functions without Xcode in runtime? I have a project which doesn't use Xcode to build the code for macOS. It would be great if I could see logs in Terminal when deprecated function is called.

My app is cross-platform and I don't use Xcode project. All localization inside app is performed with an internal code and works fine. There is a problem with localization in NSOpenPanel and NSSavePanel. They always appear on English and don't use macOS current language (French) of an user. I added the following code to Info.plist : <key>CFBundleLocalizations</key> <array>    <string>en</string>    <string>fr</string> </array> But NSOpenPanel still appears on English. I checked macOS TextEdit app which shows NSOpenPanel correctly with current OS language. Its Info.plist doesn't set any CFBundleLocalizations records. How this app tells macOS what language should be used for NSOpenPanel?

My app for macOS has two parts: editor and viewer. Where I should put a child-bundle of viewer in the main bundle? Main.app/Contents/PlugIns/Viewer.app ?
