Hello Apple Community, many thanks in advance for your help. My macOS app embeds a Python interpreter, compiled from source, including the Python executable and its associated libraries. The top-level app is built with Xcode 16.1 and it's written 100% in Swift6. For test purposes we are running the app on MacOS Sequoia 15.0, 15.1 and Sonoma 14.4. The app can be downloaded via TestFlight and Console app shows the next errors: Crash Reports python3.11 Application Specific Signatures: Unable to get bundle identifier for container id python3: Unable to get bundle identifier because Info.plist from code signature information has no value for kCFBundleIdentifierKey. tccd process error Prompting policy for hardened runtime; service: kTCCServiceAppleEvents requires entitlement com.apple.security.automation.apple-events but it is missing for accessing={TCCDProcess: identifier=[IDENTIFIER]], pid=62822, auid=502, euid=502, binary_path=[PATH TO SAMPLEAPP]]}, requesting={TCCDProcess: identifier=com.apple.appleeventsd, pid=577, auid=55, euid=55, binary_path=/System/Library/CoreServices/appleeventsd}, The next documents were helping a lot to reach the current state althought sometimes I was not sure how to apply them in this python interpreter context: Signing a daemon with a restricted entitlement Embedding a command-line tool in a sandboxed app XPC Rendezvous, com.apple.security.inherit and LaunchAgent Placing content in a bundle There are a lot of details that I will try to explain in the next lines. Once archived the app, it looks like this: SampleApp.app SampleApp.app/Contents SampleApp.app/Contents/Info.plist SampleApp.app/Contents/MacOS SampleApp.app/Contents/MacOS/SampleApp SampleApp.app/Contents/Resources SampleApp.app/Contents/Resources/Python.bundle And this is how Python.bundle looks like: Python.bundle/Contents Python.bundle/Contents/Info.plist Python.bundle/Contents/Resources Python.bundle/Contents/Resources/bin Python.bundle/Contents/Resources/bin/python3.11 <- Python executable Python.bundle/Contents/Resources/lib Python.bundle/Contents/Resources/lib/python3.11 <- Folder with python libraries This is the Info.plist associated with Python.bundle: <dict> <key>CFBundleIdentifier</key> <string>com.sampleapp.app.Python</string> <key>CFBundleName</key> <string>Python</string> <key>CFBundleVersion</key> <string>1.0</string> <key>CFBundlePackageType</key> <string>BNDL</string> </dict> For some reason Bundle Identifier is ignored. Created a Python target and added to the main app, I selected the Bundle template. In Python target I made the next customizations: Enabled the Skip Install (SKIP_INSTALL) build setting. Disabled the Code Signing Inject Base Entitlements Added entitlements com.apple.security.inherit to it, with a Boolean value of true. Tried to set Other Code Signing Flags (OTHER_CODE_SIGN_FLAGS) build setting to: $(inherited) -i $(PRODUCT_BUNDLE_IDENTIFIER) But I had to remove it because I could not get rid of this error "-i com.sampleapp.app.Python: No such file or directory" Created a python.plist and set it in the Packaging Build Settings section. I set Generate Info.plist File to No In this document: Embedding a command-line tool in a sandboxed app Says: "Add the ToolX executable to that build phase, making sure Code Sign On Copy is checked." But I could not do it to avoid duplicates, since the bundle itself contains the executable too. I'm not sure how to handle this case. Tried to add python3.11 executable in the bundle MacOS folder, but bundle executableURL returned nil and I could not use python from the code. This is how I get Python bundle from code: static var pythonBundle: Bundle? { if let bundlePath = Bundle.main.path(forResource: "Python", ofType: "bundle"), let bundle = Bundle(path: bundlePath) { return bundle } return nil } Created Python.entitlements with the next key-values: <key>com.apple.security.app-sandbox</key> <true/> and it is used in an Archive Post-action of SampleApp, in order to sign the python executable of Python.bundle as follows: codesign --force --options runtime --timestamp --entitlements "$ENTITLEMENTS_PATH" --sign "$DEVELOPER_ID_APPLICATION" "$ARCHIVE_PATH" The reason of using an Archive Post-action is becauses signing from a Python.bundle Build phase was generating errors related to Sandboxing. These are the entitlements to codesign SampleApp: <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.files.user-selected.read-only</key> <true/> <key>com.apple.security.inherit</key> <true/> </dict> Most probably I was mixing concepts and it seems created some confusion. We would really love to get some advice, Thanks!

Hi Apple community, many thanks in advance for your help. My macOS app embeds a Python interpreter, compiled from source, including the Python executable and its associated libraries. We have tried compiling the project with Xcode 16.0 and 16.1 beta 2 over MacOS Sequoia 15.0 and 15.1. The project is 100% developed in Swift6. This is how the project looks like: SampleApp.app SampleApp.app/Contents SampleApp.app/Contents/MacOS SampleApp.app/Contents/MacOS/SampleApp SampleApp.app/Contents/MacOS/bin SampleApp.app/Contents/MacOS/bin/python3.11 SampleApp.app/Contents/Resources SampleApp.app/Contents/Resources/lib SampleApp.app/Contents/Resources/lib/python3.11 SampleApp.app/Contents/Resources/Info.plist Since we want to 'initially' distribute the app directly, Python binary is signed as follows: codesign --deep --force --options runtime --timestamp --sign "$DEVELOPER_ID_APPLICATION" "$BINARY_PATH" App entitlements contain the next entries: &lt;key&gt;com.apple.security.app-sandbox&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.files.downloads.read-write&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.files.user-selected.read-only&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.files.user-selected.read-write&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.network.client&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.network.server&lt;/key&gt; &lt;true/&gt; The resulting app is signed with entitlements, notarised and stapled. Once the app is running, we can see the next errors on Console: Prompting policy for hardened runtime; service: kTCCServiceAppleEvents requires entitlement com.apple.security.automation.apple-events but it is missing for accessing={TCCDProcess: identifier=[IDENTIFIER]], pid=58826, auid=502, euid=502, binary_path=[PATH]}, requesting={TCCDProcess: identifier=com.apple.appleeventsd, pid=824, auid=55, euid=55, binary_path=/System/Library/CoreServices/appleeventsd}, Python process runs for some seconds and then the process disappears. We can not see any AMFI message on Console. Then we add to Signing and Capabilities 'Apple Events' from Hardened Runtime section. The resulting app gets signed, notarised and stapled, but when running we get only the next errors: error 09:42:32.787744+0200 SampleApp Can't find or decode reasons error 09:42:32.787832+0200 SampleApp Failed to get or decode unavailable reasons Just in case it is relevant, this is how the app interacts with Python: process.executableURL = URL(fileURLWithPath: [PATH_TO_PYTHON_BINARIE]) process.environment = environment process.arguments = arguments process.standardOutput = pipe try process.run() process.waitUntilExit() We truly appreciate any guidance, help or advice. Thanks!!
