Is there a way to check your app signature to verify if any one has tampered with the ipa file. I want to know specifically how to determine and handle this type of situation. How can i do a check for this in code(swift).

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?

This is a Math+CS Educational app written in Java. I have been able to distribute the Intel-Mac version downloaded as a .dmg (code-signed, notarized and stapled). I also need to support Apple silicon hw. I re-created the entire sw manufacturing structure on my M2 Macbook. I'm using the exact same command scripts that work on the older hardware. I am expecting the jpackage script to run the same way on the M2....but no. The first sign of trouble is I'm not getting an authentication password dialog , which I believe is thrown up by the MacOS when codesign asks to access my Keychain certificates. My keychain is setup the default way. Here is the error msg: [07:38:08.719] Running /usr/bin/codesign [07:38:08.749] java.io.IOException: Command [/usr/bin/codesign, -s, Developer ID Application: Pierre Bierre (SL7L4YU8GT), -vvvv, --timestamp, --options, runtime, --prefix, ST_DFG2D_ARM, /var/folders/v7/06pp2_5d6gz9593k96n2z0v40000gn/T/jdk.jpackage11705714069544945060/images/image-2753484488940359178/DataflowGeom2D.app/Contents/runtime/Contents/Home/lib/libnet.dylib] exited with 1 code at jdk.jpackage/jdk.jpackage.internal.Executor.executeExpectSuccess(Executor.java:90) at jdk.jpackage/jdk.jpackage.internal.IOUtils.exec(IOUtils.java:215) If I build the .dmg installer WITHOUT code-signing it, it produces a good .dmg, but I can't distribute it to my students with M2-M3-M4 rigs. The error feedback from "codesign" is nonspecific and inactionable. As a developer, I need specific, actionable error messages. I expect that from the wealthiest computer company in the world. Need the info.

Hi guys, New to publishing apps on Apple Store. I encounter some notarization error before and resolved it in this post. By solving the previous issue, I updated the Trust setting from "Always Trust" to "Use System Defaults" for Apple certificates. The codesign and notarization no longer give me any problem. But now, I encountered another issue. When I ran the .app on my local Macbook, it now gives me "zsh: trace trap" error. Dive a little further and check the crash report, I found the some details as following. Process: my_app [30652] Path: /Users/USER/my_app_path Identifier: my_app Version: 0.0.0 (???)

I made a macOS application using Swift Package and distributed it in dmg format through Apple Notary service. However, we received a report from a user that it can be launched from a disk image mounted from dmg, but when copied to /Applications, the app is broken and does not start. I looked into why this happened, I noticed that the codesign command returned different results when copying the application bundle and /Applications on the volume mounted dmg with Finder. Mounted dmg: OK ❯ codesign --verify --deep --verbose /Volumes/azoo-key-skkserv/azoo-key-skkserv.app /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: valid on disk /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: satisfies its Designated Requirement Copied by Finder: Bad codesign reports that there are 148 added/missing files. ❯ codesign --verify --deep --verbose /Applications/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app: a sealed resource is missing or invalid file added: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...) file missing: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...)

You can download dmg in github releases, mount dmg, copy it in the Finder, and check if there is a problem by running the codesign command. https://github.com/mtgto/example-utf8-mac-notarization As a result, I learned the following two things. Occurs only with resources with file names whose values change due to NFC/NFD normalization No problems occur with the resources of the application itself. Generated by the Swift Package resources that the application depends on I think this is a problem with Finder or Gatekeeper.

I added a watchkit extension to an existing app. I get this error when uploading to App Store Connect. Building the archive itself is fine: Prepared archive for uploading Upload failed error: Validation failed Missing Info.plist value. A value for the key “WKApplication”, or “WKWatchKitApp” if your project has a WatchKit App Extension target, is required in “Runner.app/Watch/watch_Watch_App.app” bundle. For details, see: https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps/setting_up_a_watchos_project have the exact same issue when bundling. I added the flag manually in a additional plist fields entry with WKApplication=1 because my Info.Plist is generated and it didn't help. I wrote a custom Run Script Phase that added the flag and that didn't help as well. I need a reply from someone from Apple here. This needs to be fixed.

In Swift I'm using unzip by launching a Process to unzip a file. I added a launchRequirement to the process in order to make sure the executable is code signed by Apple and the identifier is com.apple.unzip. After testing out my code on another machines (both physical and virtual), I found out that in some the identifier is actually com.apple.zipinfo, which broke the SigningIdentifier requirement. It's safe to assume that /usr/bin/unzip can be trusted since it's in a System Integrity Protection (SIP) location, but I'm wondering why this executable has different identifiers?

Hi, This is my first time developing for iPhone, and I believe I have encountered an unusual edge case related to user management. Background: I work at a very small company currently in the proof-of-concept stage of building an iOS app. We created an Apple account under the company name: Green Vibe, using our corporate email. Initially, I developed the app under the free account on my local iPhone, and everything worked smoothly. When NFC functionality became necessary, we upgraded to a paid Apple Developer account. At that point, I enrolled as a developer under my personal name (Or Itach) while logged in with the Green Vibe Apple account. I want to emphasize that only one Apple account was created — the Green Vibe account. The Issue: When attempting to add NFC, I was able to create the required certificate under the name Or Itach. However, when compiling the project, Xcode prompts me to enter the login password for the user Or Itach. This is problematic because there is no Apple ID associated with that name — only the Apple Developer enrollment under Green Vibe exists. Request: Could you please advise on the proper way to resolve this situation? Specifically: Should the developer enrollment be tied directly to the Green Vibe account rather than to an individual name? How can I correctly configure the account so that Xcode no longer requires a nonexistent Apple ID password? Thank you very much for your support and clarification.

Hi! I've been scratching my brain for a few days now to no avail. I have a Perl project that I need to embed within my app. Perl includes a pp command (https://metacpan.org/pod/pp) which takes the runtime binary and then slaps the Perl code at the end of the binary itself which in brings some woes in a sense that the binary then needs to be "fixed" (https://github.com/rschupp/PAR-Packer/tree/master/contrib/pp_osx_codesign_fix) by removing the linker-provided signature and fixing LINKEDIT and LC_SYMTAB header sections of the binary. Nevertheless, I've successfully gotten the binary built, fixed up and codesigned it via codesign -s '$CS' mytool (where $CS is the codesigning identity). I can verify the signature as valid using codesign -v --display mytool: Identifier=mytool Format=Mach-O thin (arm64) CodeDirectory v=20400 size=24396 flags=0x0(none) hashes=757+2 location=embedded Signature size=4820 Signed Time=5. 1. 2026 at 8:54:53 PM Info.plist=not bound TeamIdentifier=XXXXXXX Sealed Resources=none Internal requirements count=1 size=188 It runs without any issues in Terminal, which is great. As I need to incorporate this binary in my app which is sandboxed, given my experience with other binaries that I'm including in the app, I need to codesign the binary with entitlements com.apple.security.app-sandbox and com.apple.security.inherit. So, I run: codesign -s '$CS' --force --entitlements ./MyTool.entitlements --identifier com.charliemonroe.mytool mytool ... where the entitlements file contains only the two entitlements mentioned above. Now I add the binary to the Xcode project, add it to the copy resources phase and I can confirm that it's within the bundle and that it's codesigned: codesign -vvvv --display MyApp.app/Contents/Resources/mytool Identifier=com.xxx.xxx.xxx Format=Mach-O thin (arm64) CodeDirectory v=20500 size=24590 flags=0x10000(runtime) hashes=757+7 location=embedded VersionPlatform=1 VersionMin=1703936 VersionSDK=1704448 Hash type=sha256 size=32 CandidateCDHash sha256=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9e CandidateCDHashFull sha256=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9edf463ce45d1cd3f89a6a4a00 Hash choices=sha256 CMSDigest=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9edf463ce45d1cd3f89a6a4a00 CMSDigestType=2 Executable Segment base=0 Executable Segment limit=32768 Executable Segment flags=0x1 Page size=16384 CDHash=0a9f93af81e8e5cb286c3df6e638b2f78ab83a9e Signature size=4800 Authority=Apple Development: XXXXXX (XXXXXX) Authority=Apple Worldwide Developer Relations Certification Authority Authority=Apple Root CA Signed Time=9. 1. 2026 at 5:12:22 PM Info.plist=not bound TeamIdentifier=XXXXX Runtime Version=26.2.0 Sealed Resources=none Internal requirements count=1 size=196 codesign --display --entitlements :- MyApp.app/Contents/Resources/mytool <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "https://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>com.apple.security.app-sandbox</key><true/><key>com.apple.security.inherit</key><true/></dict></plist> All seems to be in order!

So I ran: xattr -l MyApp.app/Contents/Resources/mytool None listed. It is a signed binary within a signed app. There are other binaries that are included within the app and run just fine exactly this way (most of them built externally using C/C++ and then codesigned exectly as per above), so I really don't think it's an issue with the app's sandbox setup... Is there anyone who would be able to help with this? Thank you in advance!

Hello, I have this simulator made in Unity that I want to distribute as Standalone. It consists of launcher which, when users download it, downloads the game. I've built the launcher, got Developer ID Application certificate, added entitlements from: https://docs.unity3d.com/Manual/macoscodesigning.html#signing-identity I've signed the .app of the launcher and 2 dlls chatgpt recommended to sign, zipped it, notarized .zip successfully, stapled to .app and put it on Google Drive to test. I got my other MacBook Pro, downloaded the zip, tried to open it. It did open, but there is a black loading screen saying "0% progress, 0B/0B" indicating that it isn't downloading anything - no network calling. When checked using command xattr -l path/to/file.app I get the following output: com.apple.macl: @?????I???|???? com.apple.quarantine: 0083;67bf1a22;Safari;69764595-CA94-44D2-B679-A69DC4669382 There are some specifics I think are also important to mention. I tried to code-sign it, notarize it and staple it using only Terminal and I'd like to keep it that way because I am very unfamiliar with Mac so I've avoided using Xcode as much as possible I really want to avoid putting the simulator up on the App Store, so I must have Standalone solution and Standalone solution only I believe that there might be problem with needing right entitlements, but I don't know how to check which one's are needed for users to avoid using "xattr" command in terminal to allow the launcher to run because of GateKeeper I've been banging my head against the wall with this problem for over a month and I don't see the light at the end of the tunnel.

Hi, I have created a conda python environment which I have packaged into a .tar.gz (using conda-pack) and which runs correctly when extracted (in this example, it only contains the scipy package). However, when I sign the necessary files within the environment (i.e. the binaries, the dylibs, the .so files), attempting to load scipy.sparse now fails with the error "mapped file has no cdhash, completely unsigned" about one of the .so files. Furthermore, I believe that this file does in fact have a cdhash. The signing process represented by my example below has been working for about a year, and I am unsure why it has suddenly stopped working. I am on a 2020 MacBook Pro with an i7 processor and running Sequoia 15.1.1. Here is a minimal example showing the creating of the conda environment, codesigning, and the error message.

I’ve developed a macOS app, but I’ve had trouble using a script to fully codesign it and package it into a .dmg file. I was only able to complete codesigning using the third-party app itself—not via command-line scripts. Is it possible to write a script that automates the entire process of codesigning the app? To provide the best user experience for those downloading the app outside of the Mac App Store, is it correct to first package it as a .app and then wrap that into a .dmg file for distribution? Currently, the app is available on the web as a .dmg. When downloaded, it appears in a folder and can be double-clicked to launch. However, macOS displays a warning that it was downloaded from the internet. Can I use a script to remove that quarantine warning? If possible, I’d appreciate a step-by-step explanation and a sample command-line script to: Codesign the app properly Package it into a signed .dmg Remove the quarantine attribute for local testing or distribution Is the reason I was only able to codesign it inside the third-party app due to how that app was built, or can this always be done from the command line?

Yes, this is very likely the completely wrong way to do things but I would like to ask regardless. Currently with windows/linux I can perform an in-situ upgrade of an application by performing a download of the binary 'foo' and then doing a rename-and-replace and subsequently requesting the licencee to restart the program and all is good. With macOS, as the binary is within the foo.app ( Contents/macOS/foo ) I imagine I cannot perform a similar operation without breaking the signing of the foo.app itself? ....or, can I individually sign the binary foo for macOS and perform the same type of operation? Download new foo as foo.new rename current foo.app/Content/macOS/foo -> foo.old rename foo.new -> foo Restart application Again, I know this is very likely an un-macOS way of performing the task but as you can imagine with supporting cross-platform development it's usually easier to maintain a consistent method even if it's "not ideal".

Displaying attribute for a private key I see a number of applications that are allowed to access it without needing a password e.g. racoon; Keychain Access.app; Certificate Assitant.app etc.. I want to add /usr/bin/codesign to the list but the gui window that pops up when I click on + doesn't seem to allow me to do that :( How do I do it please

Hello, I am normally a windows programmer, but I am trying to get my PySide/Qt app into the app store. I'm almost there, I just have a couple of questions about the signing process. I have two laptops, one intel silicon, one mac silicon. I created 2 CSR's, one on each laptop and used them to generate 2 Mac Installer Distribution certificates and 2 Mac App Distribution certificates. When it came to downloading the provisioning profile, I selected one Mac App Distrbution Certificate on the interface at developer.apple.com, saved it and then downloaded to the appropriate laptop. I then switched the provisioning profile to the other Mac App Distribution Certificate and downloaded it to the other laptop. I then built the app and uploaded everything using xcrun altool. On the intel machine only(which has the first provisioning profile) I successfully uploaded the package but I get an email identifying lots of similar errors of the type (Lets call it error1): ITMS-90284: Invalid Code Signing - The executable XXXXX must be signed with the certificate that is contained in the provisioning profile. On the ARM machine only i get the following error (Lets call it error2): ITMS-91109: Invalid package contents - The package contains one or more files with the com.apple.quarantine extended file attribute, such as XXXXXXXX embedded.provisionprofile”. This attribute isn’t permitted in macOS apps distributed on TestFlight or the App Store. Please remove the attribute from all files within your app and upload again. On both I get the following error lets call it error3: ITMS-90886: 'Cannot be used with TestFlight because the signature for the bundle at XXXXX is missing an application identifier but has an application identifier in the provisioning profile for the bundle. Bundles with application identifiers in the provisioning profile are expected to have the same identifier signed into the bundle in order to be eligible for TestFlight.' My first inclination is that all the error1's are coming from having two sets of CSRs, Mac Distribution certificates, provisioning profiles etc. Should I have only used one CSR and made one each of the Certificates? I don't know why I have error2. I don't know where the quarantine attribute is coming from and why it would affect the mac silicon and not the intel. Any ideas? my entitlements file has the following: <key>com.apple.security.cs.allow-jit</key> <true/> <key>com.apple.security.cs.allow-unsigned-executable-memory</key> <true/> <key>com.apple.security.cs.disable-library-validation</key> <true/> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.device.bluetooth</key> Error3 is the one where I need to try a few things but knowing what is expected will help. In the provisioning profile when viewed at developer.apple.com it has the APP ID listed as the 10 digit id followed by the bundle ID but I sometimes see just the 10 digit app ID being used and sometimes the bundle ID. I know that it's up to me to figure out how to get it into the build, but knowing what it should be would be helpful. On the other hand the text "Bundles with application identifiers in the provisioning profile ..." indicates that if the application identifier was not in the provisioning profile i might get away with it, but this might be grasping at straws. If you have made it this far, thank you for reading.

Hi all, I’ve run into a signing/entitlements problem that shows up only on Big Sur (11.x). The very same .app launches perfectly on Monterey (12), Ventura (13), Sonoma (14 / 14.5) and Sequoia (15).

In the LightweightCodeRequirements framework, there is a LaunchCodeRequirement object which can be used as a requirement object for a Process for example. What I don't understand (I admit my macOS low-level knowledge is limited) is that how can this be used in a secure way that doesn't fall victim of a Time-of-Check/Time-of-Use issue. e.g. I specify a LaunchCodeRequirement via Process.launchRequirement for my process, let's say /usr/local/bin/mycommandlinetool. The LaunchCodeRequirement specifies my development team and a developer ID certificate. The process must be started in some form, before a SecCode/SecTask object can be created, rather than a SecStaticCode object (which only guarantees its validity checks to be intact as long as the file is not modified). But if the process was started, then I have no tools in my set to prevent it from executing its initialization code or similar. Then, by the time I'm able to check via SecCode/SecTask functions the LaunchCodeRequirement, I might have already ran malicious code - if mycommandlinetool was maliciously replaced. Or does the operating system use a daemon to copy the executable specified for Process to a secure location, then creates the SecStaticCode object, assesses the LaunchCodeRequirement and if passed, launches the executable from that trusted location (which would make sure it is immutable for replacement by malicious actors)? I have a hard time understanding how this works under the hood - if I remember correctly these are private APIs.

Coming from Windows, I'm finding Mac app packaging farcically complicated, to the level of a Python sketch. I mastered Windows packaging, via Inno, in an hour or so, but it has taken me, on and off, the best part of a week to get to the point I am at with the Mac OS, and I'm nowhere near finished (rather, it hasn't finished with me). Every time I surmount one hurdle, another pops up, seemingly just for the jollies. I'm currently stuck at: 'Error: HTTP status code: 403. A required agreement is missing or has expired. This request requires an in-effect agreement that has not been signed or has expired. Ensure your team has signed the necessary legal agreements and that they are not expired.' My account lists no agreements in this category. I understand the need for security, but not the labyrinthine nature of the process. An inner-party member in the former Soviet Union overheard a drunken Stalin say, “I trust no one; not even myself". Apple trusts no one, but has true contempt for developers. Is there a simple way to work through the packaging process? Let me rephrase that: please God, let there be a simpler way of working through the process! Regards, in extremis, Richard

I've signed an app, zipped it, and uploaded it to github. When I download it on another Mac, I get "it can't be opened because it could not be verified for malware". But on that computer, I can verify it with codesign, and it appears to be correct (as far as I can tell). I can copy/paste the app from my other Mac, and that copy will run without problem. sys_policy, however, gives: Notary Ticket Missing File: ReView.app Severity: Fatal Full Error: A Notarization ticket is not stapled to this application. Type: Distribution Error This is the same for the copy that runs, and the copy that doesn't. The difference between them appears to be a quarantine xattr. I can delete this, and the app launches without incident. Is this expected? Why should a signed app be quarantined just because it's been downloaded? The whole point of paying the fee is to avoid the security obstacles...! ;-)
