To learn how to develop/distribute a DriverKit driver (DEXT) and a UserClient app correctly, I am trying to run the following sample dext and app. https://developer.apple.com/documentation/driverkit/communicating-between-a-driverkit-extension-and-a-client-app?language=objc I walked throught steps in README.md included in the project and faced issues. First, I referred the "Configure the Sample Code Project" section in the README.md and configured the sample code project to build with automatic signing. I could run the app and activate the dext successfully and made sure the app could communicate with the dext. Next, I tried the manual signing. I followed steps described in the "Configure the Sample Code Project" section carefully. The following entitlements has already been assigned to my team account. DriverKit Allow Any UserClient Access DriverKit USB Transport - VendorID DriverKit I could build both app and dext and could run the app. However, when I clicked the "Install Dext" button to activate the dext, I got the following error: sysex didFailWithError: extension category returned error Am I missing something? I would also like to know detailed steps to publicly distribute my dext and app using our Developer ID Application Certificate, as README.md only shows how to configure the project for development.

Hello! I've just recently discovered LaunchCodeRequirement API and I'm exploring how it works compared to existing alternatives available for macOS versions below 14.4. Some questions I have with regards to safety of older and newer APIs examining the given example: func runProcess(executableURL: URL) throws { let process = Process() process.executableURL = executableURL if #available(macOS 14.4, *) { process.launchRequirement = try LaunchCodeRequirement.allOf { ValidationCategory(.developerID) SigningIdentifier("some-signing-identifier") TeamIdentifier("some-team-identifier") } } else { try secStaticCodeCheckValidity(executableURL) // Point #1 } do { try process.run() // Point #2 if #available(macOS 14.4, *) { // process.launchRequirement should take care of the process // and kill it if launchRequirement constraint is not satisfied } else { try secCodeCheckValidity(process.processIdentifier) // Point #3 } process.waitUntilExit() } catch { process.terminate() throw error } // Point #4 guard process.terminationReason == .exit else { throw SomeError() } } let requirement = """ anchor apple generic and identifier = "some-signing-identifier" and certificate 1[field.1.2.840.113635.100.6.2.6] and certificate leaf[field.1.2.840.113635.100.6.1.13] and certificate leaf [subject.OU] = "some-team-identifier" """ func secStaticCodeCheckValidity(_ executableURL: URL) throws { // Init SecStaticCode from `executableURL` // Init SecRequirement from `requirement` let flags = SecCSFlags(rawValue: kSecCSBasicValidateOnly) guard SecStaticCodeCheckValidityWithErrors(code, flags, secRequirement, nil) == errSecSuccess else { throw CodeSignError() } } func secCodeCheckValidity(_ processIdentifier: Int32) { // Init SecCode from `processIdentifier` // Init SecRequirement from `requirement` guard SecCodeCheckValidityWithErrors(code, [], secRequirement, nil) == errSecSuccess else { throw CodeSignError() } } Before macOS 14.4+ flow There's still a small chance that between checking executable binary codesign requirement (Point #1) and launched process' one (Point #3) the binary could be replaced with something malicious and even get some CPU between Points #2 and #3 so technically it can't be 100% safe. Is that a correct statement? Any advices on making it safer? macOS 14.4+ flow Now let's see how launchRequirement is better. I guess initialized launchRequirement gets evaluated on running the process (Point #2). What does it exactly check? Executable at URL before launching the process (as OnDiskConstraint) or launched process (as ProcessConstraint)? Is there any chance the process gets some CPU before it's killed in case of failed codesign check? Any way to distinguish between codesign requirement termination and other reasons at point #4? It returns SIGKILL (9) as terminationStatus but it's not precise enough to be sure it was killed due to failed requirement check. I guess newer SecStaticCodeCheckValidityWithOnDiskRequirement & SecCodeCheckValidityWithProcessRequirement are the same as SecStaticCodeCheckValidityWithErrors & SecCodeCheckValidityWithErrors but a little simpler and can't be used as a 'more secure' way of validating codesign requirement. Thanks, Pavel

On MacOS, I know that App Groups (com.apple.security.application-groups) do not require a provisioning profile. I was wondering if it's possible to sign them "ad hoc" and have it work? So maybe use a random TEAMID prefix and have it work? I would only need the app to work locally (for testing), not be distributed in that fashion, of course.

Hi Developers, I'm encountering persistent validation errors in Xcode 16.3 (16E140) on macOS 15.4.1 (24E263) with M1 when archiving and distributing a macOS app (Developer ID signing + notarization). App Structure: A native Swift/Obj-C wrapper app that launches a nested .app inside its Resources. The nested app is built with PyInstaller and includes: A Python core Custom C++ binaries Many bundled .so libraries (e.g., from OpenCV, PyQt/PySide) Issues During Validation: App Sandbox Not Enabled Error: App Sandbox missing for NestedApp.app/Contents/MacOS/NestedExecutable. Question: For Developer ID (not App Store), is sandboxing strictly required for nested PyInstaller apps? If the wrapper is sandboxed, must the nested app be as well? Given the PyInstaller app's nature (requiring broad system access), how should entitlements be managed? Upload Symbols Failed Errors for missing .dSYM files for: The nested app’s executable Custom C++ binaries .so files (OpenCV, PyQt, etc.) These are either third-party or built without DWARF data, making .dSYM generation impractical post-build. Question: Are these symbol errors critical for Developer ID notarization (not App Store)? Can notarization succeed despite them? Is lack of symbol upload a known limitation with PyInstaller apps? Any best practices?

My app designer cannot sign his code changes. He says the only way he can sign his code is for me to give him my Admin privileges. I have revoked and recreated my certificate, hoping to get a private passkey, but there was no private passkey issued with the certificate. Help, please?

I'm working on a build system similar to Bazel where each build action runs in a sandbox. The sandbox contains only the files that the user defined as input to ensure that the build action doesn't have any implicit dependencies. Bazel achieves this by creating a "symlink forest" to the original source files. This works, but I have observed fseventsd using significant CPU during a Bazel build, presumably because of all the symlinks that get created. Is there a way to disable file events for a directory or a volume? The "File System Events Programming Guide" in the Documentation Archive mentions placing an empty file named no_log in the .fseventsd directory at the root of the volume, but when testing on macOS 15.5 with APFS that appears to no longer work. Related, is a "symlink forest" the best way to create a sandbox like this? Or is there a different method one can use to provide a view of a subset of the files in a directory tree? I read up on the App Sandbox but that seems too coarse grained. Something like Linux's overlayfs would work well, and maybe one can achieve a similar functionality with firmlinks? Curious about folks thoughts here. Thanks in advance!

Can someone tell me the applications requirements for using the secure enclave on MacOS? Does the application need to be signed with the secure-enclave entitlement in order to use it? Since this is a restricted entitlement, does my App ID need approval to use it from Apple? Currently I'm building in XCode 16 on Sequoia (15.5) using developer signing. My application is a C/C++ daemon running as plist out of /Library/LaunchDaemons. I have also built it as an application using the instructions here but this has not lead to a solution: https://developer.apple.com/documentation/xcode/signing-a-daemon-with-a-restricted-entitlement/ When I run my application from the command line via sudo signed but without the secure-enclave entitlement enabled in my entitlements file it runs. The first call to: SecAccessControlRef access = SecAccessControlCreateWithFlags( kCFAllocatorDefault, kSecAttrAccessibleWhenUnlockedThisDeviceOnly, kSecAccessControlPrivateKeyUsage, &error); succeeds without error. The call to create the key using: SecKeyRef privateKey = SecKeyCreateRandomKey(attributes, &error); then fails with error: (OSStatus error -50 - Failed to generate keypair) Here are the setup attributes (keySize = 256): CFDictionarySetValue(attributes, kSecAttrKeyType, kSecAttrKeyTypeECSECPrimeRandom); CFDictionarySetValue(attributes, kSecAttrKeySizeInBits, keySize); CFDictionarySetValue(attributes, kSecAttrLabel, keyName); CFDictionarySetValue(attributes, kSecAttrApplicationTag, keyLabel); CFDictionarySetValue(attributes, kSecAttrTokenID, kSecAttrTokenIDSecureEnclave); // Store in the Secure Enclave CFDictionarySetValue(attributes, kSecAttrKeyClass, kSecAttrKeyClassPrivate); CFDictionarySetValue(attributes, kSecAttrAccessControl, access); CFDictionarySetValue(attributes, kSecAttrIsPermanent, kCFBooleanTrue); // persist key across app restarts and reboots CFDictionarySetValue(attributes, kSecAttrCanEncrypt, kCFBooleanTrue); CFDictionarySetValue(attributes, kSecAttrCanDecrypt, kCFBooleanTrue); CFDictionarySetValue(attributes, kSecAttrAccessible, kSecAttrAccessibleWhenUnlockedThisDeviceOnly); CFDictionarySetValue(attributes, kSecReturnPersistentRef, kCFBooleanTrue); When I run the application signed and include the "com.apple.developer.secure-enclave" in my entitlements file it crashes at startup. I believe this is to be expected based on above. How do I proceed such that my application can use the secure enclave correctly?

Hello, I’m facing an issue with enabling In-App Purchases (IAP) for my iOS app, and it’s causing provisioning errors during the build process. Issue: • In Apple Developer Portal → Certificates, Identifiers & Profiles, the In-App Purchase capability is checked but grayed out, so I can’t modify it. • In Xcode, under Signing & Capabilities, I don’t see In-App Purchase listed. • When trying to build, I get the following error: Provisioning profile “BillionMines_Dev_Profile” doesn’t include the com.apple.developer.in-app-purchase entitlement. • Automatic signing in Xcode fails with: Xcode failed to provision this target. What I Have Tried: 1. Verified that my App ID is explicitly defined (not a wildcard ID). 2. Regenerated and downloaded a new Provisioning Profile, ensuring it matches my app. 3. Confirmed that In-App Purchase is enabled in App Store Connect under Features. 4. Cleaned the build folder and restarted Xcode. 5. Manually added com.apple.developer.in-app-purchase to my .entitlements file. Questions: • Why is the In-App Purchase option grayed out in Certificates, Identifiers & Profiles? • How can I ensure my provisioning profile includes the com.apple.developer.in-app-purchase entitlement? • Are there additional steps required to fully activate In-App Purchases? Any help would be greatly appreciated! Thanks in advance.

Once I have built my macOS .app and signed it I run notarytool using this simple shell script: #!/bin/sh ditto -c -k --keepParent "$1.app" "$1.zip" xcrun notarytool submit "$1.zip" --keychain-profile "Notary Profile for DeepSkyStacker" --wait xcrun stapler staple $1.app rm -f $1.zip How can I export that "keychain-profile" (notary profile) so I can use it in CI/CD actions? Clearly I don't wish to expose the full invocation of xcrun notarytool store-credentials.

In the past it was relatively easy to download from the developer portal both the app signing and installer signing certs so that I could sign AppleScripts from Script Editor when exporting them and when building packages in Jamf Composer. I went to set that up today and it seems things have changed in the last few years since I've had to set this up. I've been unable to sort this out and would love some help. I'm looking for a tutorial on doing this that walks someone step-by-step through the process for obtaining the certs (yes, I have dev account) and setting them up in keychain and then making use of them. Thanks!

The driver does not show up in the app settings after switching to “DriverKit USB Transport - VendorID”. Previously, the app used “DriverKit USB Transport (development)” and everything worked as expected. The entitlements looked like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.developer.driverkit</key> <true/> <key>com.apple.developer.driverkit.transport.usb</key> <array> <dict> <key>idVendor</key> <string>*</string> </dict> </array> </dict> </plist> I received approval to use “DriverKit USB Transport - VendorID”.

Can you please revoke my developer id application and installer certs? So i may recreate. I deleted the private key by mistake before realizing i cannot recreate everything using the developer website portal. I dont have macos backup or did i backup my certs with attached pkey. I just did not realize this was important until now. Please help as Im now blocked. I opened a case too but i have not yet got a response. its been 3 days now. case id: 20000093632858

Hello Apple Developer Support, We are experiencing an issue when programmatically installing a trusted root certificate on EC2 macOS instances (ARM-based), running the latest version of macOS 14.7.5 (Build 23H527). We are using the following command as part of our automated setup process: sudo security authorizationdb write com.apple.trust-settings.admin allow sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain "$CERT_NAME" sudo security authorizationdb remove com.apple.trust-settings.admin This fails with the following message: SecTrustSettingsSetTrustSettings: The authorization was denied since no user interaction was possible In the past, as sugested in other posts (https://developer.apple.com/forums/thread/671582) we were able to bypass this issue by running: sudo security authorizationdb write com.apple.trust-settings.admin allow This worked successfully in prior versions, including earlier 14.x releases, and continues to work on Intel-based macOS instances. However, in macOS 14.7.5 (on ARM), this approach no longer works. We suspect this may be due to a change in how System Integrity Protection (SIP) is enforced, especially on EC2 ARM. Questions: Has Apple introduced any changes in macOS 14.7.5 that prevent modifying trust settings via security CLI on headless or non-interactive sessions? Is there an approved or documented way to install system-level trusted certificates programmatically on macOS 14.7.5 (ARM)? Are there alternatives for setting trustRoot certs in non-GUI environments, such as virtualized or cloud-hosted macOS instances? As further information we were thinking to use MDM Profiles but looks like it is also blocked Thanks

Hello everyone. I have a simple doubt, I receive an email informing that the Apple Distribution certificate will expire. I create one new in the Developer portal with one year duration. My doubt is, I need to do something more like open again the app in Xcode, insert new certificate and build it again, send to apple and everything? Or just creating this certification is enough? Is possible to increase this certification time or auto renew? Thank you!!!

In XCode I create and export a notarized app for "direct distribution". I then create a tar file of the exported .app to distribute to my users. Until today this worked fine. Now when the users try to run the app it pops up a dialog saying "app is damaged and can't be opened. You should move it to the Trash." It is possible to ctrl-click on the app and force it to run but, I think, whether this works or not will depend on system settings and not all users have root access to modify settings. Even simply copying the .app folder from the command line will cause this error.
