Error 65 upon stapling - cannot reset trust settings
Hi, I'm getting error 65 upon stapling and I am suspecting that non-default trust settings may be the reason as outlined here: Unfortunately whatever I do, I can't seem to reset the trust settings to their default values (removing the blue/white "+"), I'm not being asked for credentials upon closing the certificate window. I have also tried to unlock the System Roots key chain, to no avail. Also, when running security dump-trust-settings -d I get Number of trust settings : 0 for all certificates. Any ideas as to what I may be doing wrong? Is there any other setting that may be involved? Thanks!

Multiple Executables in a Single Bundle Fails to Launch Others After Codesign
We have a rather complex network of dependencies for our application stack and, from it, we create multiple unique executables that are placed into the Contents/MacOS directory of our bundle. MyApp.app `- Contents/ `- Frameworks/... `- MacOS/ `- exec_a `- exec_b `- Resources/... Both executables require the same dependencies (and use the same shared .dylib files built as targets in the same project) so it makes sense for them to be in the same place rather than in their own .app folder as I understand it. Qt Libs -> core_lib.dylib -> gui_lib.dylib -> exec_a `-> exec_b etc. We've confirmed build artifacts are correct and the rpath/dependencies are all clean. When in development, all executables run as expected and we can command exec_a (the executable we're listing in the primary Info.plist) to launch exec_b at any time. Once the bundle is signed, however, we cannot get exec_b to launch in any capacity. Even lldb dies right away because it can't attach to anything. We assume this is something in the gatekeeper area of blocking these additional executables. We get the following when trying to run those additional exes in any way: Trace/BPT trap: 5 We're using macdeployqt to finalize the bundle and bring in the correct packages - perhaps something it's doing is causing the additional executables to fail or we're missing an entitlement. We've submitted the app to TestFlights successfully even with these invalid executables to see if there was something the processing of the app would find but so far nothing. We've seen other example of applications with multiple executables in the same MacOS directory and are wondering what the difference is. Any hints or guidance would be great. Thank you!

Notarization.
Hi, I've code-signed my app and notarized it, and created a DMG, and when I slacked it or airdropped it to someone for testing the FIRST time they open it, they get a warning that it was Slacked or airdropped to them and do they want to open it. if they say yes everything is fine. So looking through here someone said I need to sign the app and then make a dmg and sign the dmg and then send that for notorization and then staple that. So I did, and I still get a warning the first tie someone try's to run it. What am I doing wrong? I know I can buy software and not get a warning from apple. so how do I get my app to work correctly like that?

Problems with new Developer ID certificate
My Developer ID certificate will expire in few days, so I downloaded and installed new certificate in login keychain. However my key is still linked to my old certificate. I have my .p12 but even if I delete the old certificate from login keychain and reinstall the .12 file, my old certificate reappears in the login keychain. I tried to select the new certificate in the login keychain and choose Files > Export Items (in Keychain Access) but in the Save dialog under File Format the "Personal Information Exchange (.p12)" option is grayed out. How can I generate a key/.p12 file that will be linked to my new certificate?

Xcode archive DriverKit application
I am trying to build a release for an application that installs a DriverKit driver. I created a Developer ID Application Profile with a valid certificate but I'm coming across this error in Xcode 16.3 that is preventing me from archiving: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile. I thought I needed a Dev ID Application profile to distribute the application and that a Development profile is for testing. Is there something I'm missing?

How does xpc_connection_set_peer_code_signing_requirement work?
I have created a XPC server and client using C APIs. I want to ensure that I trust the client, so I want to have a codesigning requirement on the server side, something like - xpc_connection_set_peer_code_signing_requirement(listener, "anchor apple generic and certificate leaf[subject.OU] = \"1234567\"") This checks if the client code was signed by a code-signing-identity issued by Apple and that the teamID in the leaf certificate is 1234567. My questions are- Is using teamID as a signing requirement enough? What else can I add to this requirement to make it more secure? How does xpc_connection_set_peer_code_signing_requirement work internally? Does it do any cryptographic operations to verify the clients signature or does it simply do string matching on the teamID? Is there a way actually verify the clients signature(cryptographically) before establishing a connection with the server? (so we know the client is who he claims to be)

productbuild hangs with no output in github actions
I am running into this error with productbuild in github actions where the program hangs with a specific developer id. I have verified that my certification files are properly uploaded etc. and i am able to run this without the --sign command online and with --sign offline. if i sign with a "3rd party mac developer installer: ***" it will run but then crash on stapling because this isn't the actual org i want to staple and don't really need to verify that i could staple with this other license since it is my personal license and i will be leaving this job soon so setting up all my other certs is a waste of time since it doesn't solve the problem. When i use my bosses/org "Developer ID Installer: ***" productbuild just hangs. I am at a loss here... the acutal command running is productbuild --resources ./resources --distribution distribution.xml --sign "${{ secrets.DEVELOPER_ID_INSTALLER }}" --timestamp "${{ env.ARTIFACT_NAME }}.pkg" I have confirmed that my distribution file is fine etc. because I can productbuild without signing fine. Any suggestions on where to go?

CodeSign with out Certificate and Profile
We are facing issue with resigning the app which is developed by 3rd party. In this app we have Sharing functionality feature for which we have enabled Associated Domains capability. When we are signing the app with our certificate and profile this functionality is not working i.e when we are clicking on shared link in the app it is redirecting to app store page instead of content link. However, when 3rd party is directly using our certificate & profile then that functionality is working as expected. Could you please help us with the above issue why it is not working when we are resigning with our certificate and profile?

Persistent “com.apple.security.get-task-allow” entitlement after signing¬arizing
After signing and notarizing our application, the entitlement “com.apple.security.get-task-allow” is removed. However, we want this entitlement to remain and we want to be able to create a corefile when needed. Is it possible to make the “com.apple.security.get-task-allow” entitlement persistent after signing and notarizing, so that our application can create a corefile?

Awaiting assistance from a DTS engineer regarding a peculiar notarization issue.

How to move code signing certificates to another Mac
Hi, I recently created and installed new code signing certificates/keys on my main Mac. How to easily copy these certificates/keys to my another Mac with the same Apple ID? Earlier Quinn suggested: "The easiest way to do this is use Xcode’s import/export feature. Launch Xcode, choose Xcode > Settings, select Accounts, select the account in question, then choose Export Apple ID and Code Signing Assets from the action (…) menu." And it worked fine in 2020-2021. However import/export options are no longer available in XCode 16 anymore. Please suggest a simple solution.

Struggling to Notarize Electron macOS App – Stuck for Hours
Hey everyone, I've been trying to notarize my Electron macOS app for the past two days without any success. My longest attempt took nearly 4 hours, and my current attempt has already been running for 2 hours and 26 minutes. From what I can see in the logs, the signing step has completed successfully, and the app is currently in the notarization stage. But it's been stuck there with no real updates or progress indicators. Is this kind of delay normal? Has anyone else experienced such long notarization times? Any help or insight would be greatly appreciated! Thanks in advance.

SystemPolicyAllFiles code signing requirement
Hello. I have an enterprise application that requires specific privileges to execute correctly on MacOS. One of these privileges is SystemPolicyAllFiles (aka Full Disk Access), as we use the endpoint security framework. When we distribute our application, we generate: A signed, notarized pkg consisting of our application binaries. An MDM-compatible .mobileconfig, which contains the SystemPolicyAllFiles setting. We expect our users to install both to get the application to function correctly. However, we have three environments we deploy to: Internal (local development on a developer's workstation), "development" (where features are integrated prior to release) and "production" (what our customers get). For local, our developers create an Apple account and use a Mac Development certificate for signing. They also generate their own embedded.provisionprofile and drop that into their local installation config. For development/production, we use our Developer ID certificate and Developer Installer certificate, with an endpoint security embedded.provisionprofile bound to those. However, when we generate a .mobileconfig, we need to include a CodeRequirement (CR) for SystemPolicyAllFiles. I've been retrieving this using codesign -dr - ... (i.e., the designated requirement aka DR). However, the designated requirement is very specific to the certificate, which is problematic specifically for local development, where each developer has their own Mac Development certificate. Here's what the relevant section of our generated mobileconfig looks like right now: &lt;dict&gt; &lt;key&gt;SystemPolicyAllFiles&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;Allowed&lt;/key&gt; &lt;true/&gt; &lt;key&gt;CodeRequirement&lt;/key&gt; &lt;string&gt;identifier "com.example.app and anchor apple generic and certificate 1[field.1.2.840.113635.100.6.2.6] /* exists */ and certificate leaf[field.1.2.840.113635.100.6.1.13] /* exists */ and certificate leaf[subject.OU] = &lt;TEAMID&gt;&lt;/string&gt; &lt;key&gt;Comment&lt;/key&gt; &lt;string&gt;app&lt;/string&gt; &lt;key&gt;Identifier&lt;/key&gt; &lt;string&gt;com.exmple.app&lt;/string&gt; &lt;key&gt;IdentifierType&lt;/key&gt; &lt;string&gt;bundleID&lt;/string&gt; &lt;key&gt;StaticCode&lt;/key&gt; &lt;false/&gt; &lt;/dict&gt; &lt;/array&gt; &lt;/dict&gt; That's in a format that works for our Developer ID cert, but the DR for the Mac Development certificate looks like: identifier "com.example.app" and anchor apple generic and certificate leaf[subject.CN] = "Mac Developer: John Doe (12ABC34567)" and certificate 1[field.1.2.840.113635.100.6.2.1] /* exists */ Question: Is it possible to relax the code requirement so that it is generic enough to cover all Mac Developer certificates and Developer ID certificates we use? If not, is there a way to have one code requirement for our Mac Developer certificates and a separate CR for our Developer ID certificate? My use case is deploying a static "local" .mobileconfig using our internal company MDM (Apple Business Essentials) to all developer workstations so we don't have to have each developer manually configure their system for the software to run. Thanks! D

Not Allowed To Open Rust Binary In Terminal
Hi, I am a long time programmer in C#, and newer to Rust, and a rookie to MacOS 15.1. Over the past few days I have made numerous attempts to run a Rust GUI binary that I compiled on Mac. Here are some examples of things I have tried using. Executable compiled in M1 mac not running on Apple Silicon Mac - help - The Rust Programming Language Forum And here.... How to run unsigned apps in macOS 15.1 Also here... "sudo spctl --master-disable" There are many more that I have tried. I also tried moving the binary from my developer folder to the Application folder and running.... xattr -r -d com.apple.quarantine /Applications/csv Note that "csv" is the name of my binary. You have probably seen this 100 times, so can you point me to me to something that allows my Rust binaries to run under MacOS? PS The Rust program code works just fine under Linux. I can either type Cargo Run and run the binary from the Terminal or go directly to the executable and double click on it to open the GUI application. The only thing that MacOS lets me do it open the GUI from the Terminal. Commander One says that I do not have the proper credentials to open the file directly. Finder also does not allow me to open the binary directly. Thanks, Jim
