Verify an app before sending to Notary service
Hi, we are sending MacOS apps packaged in a ZIP archive or DMG disk image to the Notary Service. Before we send the app for notarization, we check the code signature via command codesign -vvv --deep --strict /path/to/app_or_bundle The result is positive and it does not provide any gaps. (And yes, we are following the inside out code signing approach, mentioned at Using the codesign Tool's --deep Option Correctly) Unfortunately, the result of the Notary service provided that one file has no signature, which was not detected by the signature verification command. The path of the binary was in <app_name>.app.zip/<app_name>.app/Contents/Resources/inst/<binary> How I can be verify like a the Notary service does it on our side? Best regards, Stefan

Notarization taking 3.5–4.5 hours for large macOS apps — is this expected?
Hello, We are currently using Apple Notarization (notarytool) for distributing a macOS app, and we are experiencing very long notarization times for large app bundles. [Issue] For apps with large binary sizes, notarization consistently takes around 3.5 to 4.5 hours from submission to completion. This delay is causing practical issues in our release pipeline, especially when: A hotfix or urgent update is required Multiple builds must be notarized in a short time CI/CD-based distribution is expected to complete within a predictable timeframe [Environment] Platform: macOS Notarization method: notarytool Distribution: Outside Mac App Store App size: 100 GB~ (compressed ZIP) Signing: Hardened Runtime enabled, codesigned correctly Submission status: Successfully accepted, but processing time is very long [What we have confirmed] The notarization eventually succeeds (no failures) Re-submitting the same build shows similar processing times Network upload itself completes normally; the delay is in Apple-side processing Smaller apps complete notarization much faster [Questions] Is a 3–4+ hour notarization time expected behavior for large macOS apps? Are there recommended best practices to reduce notarization processing time for large binaries? For example, splitting components, adjusting packaging, or specific signing strategies Is there any official guidance or limitation regarding notarization queueing or processing based on app size? Are there known service-side delays or regional differences that could affect processing time? Any insight or confirmation would be greatly appreciated, as this directly impacts our production release workflow. Thank you.

Signed app can't be verified
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...! ;-)

Notarization submissions stuck "In Progress"
These have been stuck in progress for a long time. Usually this process is fairly quick for this app: id: 92caae7f-1796-4928-bb35-72f5f2667786 id: 3645e93f-a8ac-4826-8a4a-690f980dde8e id: 3645e93f-a8ac-4826-8a4a-690f980dde8e What can be done, it is holding back deployments :(

Does NETunnelProvider (Packet Tunnel) require a special entitlement for App Store VPN apps?
I’m working on an iOS VPN app and looking into using NETunnelProvider (Packet Tunnel) for the VPN implementation. From the documentation it seems that Packet Tunnel is required for VPN protocols like OpenVPN, but the Packet Tunnel capability doesn’t appear to be available by default. Does using NETunnelProvider / Packet Tunnel require a special entitlement to be enabled by Apple for App Store apps? If so, what is the general process for requesting or enabling that entitlement?

build failure due to certificates not matching
i am creating a app on "appmysite" while it runs its build test an error message pops up saying build failed. "it seems your app build has encountered an issue. the certificate used to generate the uploaded provisioning profile does not match the uploaded certificate." I understand why its saying it because the uploaded certificate had to be uploaded as ".p12". The certificate in the provisioning profile is made of ".cert". I am using a apple mac book and a xenovo windows computer. Im simply trying to figure out how to put the ".p12" certificate into the provisioning profile? whenever i go to my developer account and try to create a new provisioning account with the new ".p12" certificate. The only options that pop up for me to select are only the certificates that are in ".cert" form. I've tried exporting through "key access" and they show up in my files but no way to transfer to my developer account to combine it with a provisioning account. Any help is greatly appreciated, this is literally the only thing keeping my app from being ready for submission to review. ive been stuck on this for 3 days.

"Application damaged and can't be opened' error prompt on 15.6.1 Sequoia
We have an application which keeps throwing the error "application is damaged and cannot be opened. You should move it to Trash" I have already referred to the documentation: https://developer.apple.com/forums/thread/706379 and https://developer.apple.com/forums/thread/706442 I have checked the following possible root causes: Codesign of the application using the codesign command Notarization of the application using the spctl command Executable permissions Checked for the presence of "com.apple.quarantine" flag for the application using xattr -l <path to executables" Checked the bundle structure None of the above listed items seemed to be a problem and are as expected. Can you please help us understand what could cause this issue and how to resolve this without recommending an uninstall/reinstall of the application?

I can't see Developer ID Installer option
I was reading a tutorial for obtaining an Apple Developer ID Installer certificate in order to distribute my .pkg outside the Mac App Store. However in the Certifcates/add page I'm am unable to see the required certificate (Developer ID Installer). Do I need to get some extra permissions to view this option or was it removed/moved to somewhere else?

App notarization is taking long
Hi, I read that notarization should be fairly quick. I thought that it was stuck, so I ended up sending a few submissions of the same app. I was wondering if you'd able to tell me the status of my latest submission (id: a094f93d-8bb2-47fe-a411-b6e357456ec7). It has been saying "In Progress" for over 3 hours now. If it is held for in-depth review, would you be able to tell me what's the wait period is like? Thanks!

App Translocation Notes
App translocation, officially known as Gatekeeper path randomisation, comes up from time-to-time. The best resource to explain it, WWDC 2016 Session 706 What’s New in Security, is no longer available from Apple so I thought I’d post some notes here (r. 105455698 ). Questions or comments? Start a new thread here on DevForums, applying the Gatekeeper tag so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" App Translocation Notes Gatekeeper path randomisation, more commonly known as app translocation, is a security feature on macOS 10.12 and later. When you run a newly downloaded app, the system executes the app from a randomised path. This prevents someone from taking an app that loads code from an app-relative path and repackaging it to load malicious code. IMPORTANT The best way to prevent your app from being tricked into loading malicious code is to enable library validation. You get this by default once you enable the hardened runtime. Do not disable library validation unless your app needs to load in-process plug-ins from other third-party developers. If you have an in-process plug-in model, consider migrating to ExtensionKit. The exact circumstances where the system translocates an app is not documented and has changed over time. It’s best to structure your app so that it works regardless of whether it’s translocated or not. App Translocation Compatibility Most apps run just fine when translocated. However, you can run into problems if you load resources relative to your app bundle. For example, consider a structure like this: MyApp.app Templates/ letter.myapp envelope.myapp birthday card.myapp Such an app might try to find the Templates directory by: Getting the path to the main bundle Navigating from that using a relative path This won’t work if the app is translocated. The best way to avoid such problems is to embed these resources inside your app (following the rules in Placing Content in a Bundle, of course). If you need to make them easily accessible to the user, add your own UI for that. For a great example of this, run Pages and choose File > New. App Translocation Limits There is no supported way to detect if your app is being run translocated. If you search the ’net you’ll find lots of snippets that do this, but they all rely on implementation details that could change. There is no supported way to determine the original (untranslocated) path of your app. Again, you’ll find lots of unsupported techniques for this out there on the ’net. Use them at your peril! If you find yourself using these unsupported techniques, it’s time to sit down and rethink your options. Your best option here is to make your app work properly when translocated, as illustrated by the example in the previous section. App Translocation in Action The following steps explain how to trigger app translocation on macOS 13.0. Keep in mind that the specifics of app translocation are not documented and have changed over time, so you might see different behaviour on older or new systems: To see app translocation in action: Use Safari to download an app that’s packaged as a zip archive. My go-to choice for such tests is NetNewsWire, but any app will work. Safari downloads the zip archive to the Downloads folder and then unpacks it (assuming your haven’t tweaked your preferences). In Finder, navigate to the Downloads folder and launch the app. When Gatekeeper presents its alert, approve the launch. In Terminal, look at the path the app was launched from: % ps xw | grep NetNewsWire … /private/var/folders/wk/bqx_nk71457_g9yry9c_2ww80000gp/T/AppTranslocation/C863FADC-A711-49DD-B4D0-6BE679EE225D/d/NetNewsWire.app/Contents/MacOS/NetNewsWire Note how the path isn’t ~/Downloads but something random. That’s why the official name for this feature is Gatekeeper path randomisation. Quit the app. Use Finder to relaunch it. Repeat step 5: % ps xw | grep NetNewsWire … /private/var/folders/wk/bqx_nk71457_g9yry9c_2ww80000gp/T/AppTranslocation/C863FADC-A711-49DD-B4D0-6BE679EE225D/d/NetNewsWire.app/Contents/MacOS/NetNewsWire The path is still randomised. Quit the app again. Use the Finder to move it to the desktop. And relaunch it. And repeat step 5 again: % ps xw | grep NetNewsWire … /Users/quinn/Desktop/NetNewsWire.app/Contents/MacOS/NetNewsWire The act of moving the app has cleared the state that triggered app translocation.

Entitlement not found
Dears, this is my first ever piece of code on Mac. I wanted to try ShazamKit. I created App Id and enabled App Service ShazamKit. I properly configured my app (a very small test app) with the proper boundle id, Team and entitlements file. I keep receiving this error in the Signing in section: Automatic signing failed Xcode failed to provision this target. Please address the following issues preventing automatic signing from creating a valid profile. Entitlement com.apple.developer.shazamkit not found and could not be included in profile. This likely is not a valid entitlement and should be removed from your entitlements file I noticed the message is mentioning "profile"...does it refer to a "Profile" as in "Certificate"/"Identifiers"/"Devices"/"Profiles"/"Keys"/"Services" option? I did not create any "Profile". I just enabled the App Service under "Certificates, Identifiers & Profiles"=>"Identifiers"=>"Edit your App ID Configuration"=>"App Services" Thx!

certificates expired, created new certificates and missing Mac App Distribution
Hi, My certificates expired and I created new ones. But now Xcode shows me in Apple Accounts status of Mac App Distribution that the Missing Private... Howto fix the missing private key? I need to sign a .pkg for upload with Transporter. Further I generated a CSR for App License Delivery ALD certificates. https://developer.apple.com/help/account/certificates/create-a-certificate-signing-request/ And with App Store Connected I created new certificates. In Xcode I had to remove the Apple Account and add it again, after altering currency. This procedure was described somewhere because Xcode was not able to connect my account. This is fixed now.
