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.

Signed App Opens But Doesn't Recognise Plugin
I have been trying to package a FileMaker 18 runtime app* for Mac distribution for - oh - a year and a half on and off (the Windows version was packaged in an afternoon). I succeeded - or thought I had - until I updated to Tahoe. Now my packaging process does everything it did formerly (creates the DMG, etc.), but when opened, fails to see/load a third-party plugin (BaseElements.fmplugin). Does anyone know why this should be? I have attached 4 of my build files in the hope that someone can point me in the right direction. Thanks in advance for any advice you may provide. Regards, L *Claris deprecated the runtime feature years ago, but it still runs and is useful for proof of concept. P.S. A contributor to an earlier query kindly suggested I go down the zip file or pkg installer route, rather than the DMG route. I tried doing as much but found both as susceptible to Mac spaghetti signage. build_all.txt repair_and_sign.txt build_dmg.txt notarize_dmg.txt

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...! ;-)

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!

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.

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 :(

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!

Signing succeeds but validate fails with "Missing code-signing certificate"
We have a command line script that runs xcodebuild to make an archive, then runs xcodebuild again to export the archive to make an ipa, and then runs "altool --validate-app" to check that everything will be fine for a subsequent upload to the app store. This has been working fine for a few years but recently stopped working and we cannot figure out why. The validation fails with this error: ERROR: [altool.105912F20] Validation failed (409) Invalid Provisioning Profile. The provisioning profile included in the com. bundle [Payload/.app] is invalid. [Missing code-signing certificate]. A distribution provisioning profile should be used when uploading apps to App Store Connect. (ID: ) The project is configured with 'Automatically manage signing' unchecked, and the profile was created on developer.apple.com/account/resources/profiles and the matching profile magically appears in the "Provisioning Profile" drop down in Xcode. The profile was created with two certificates checked, but examining the embedded.mobileprovision profile that ends up in the compiled ipa payload it appears to contain 19 certificates (probably all of them for this org?). Is there a way to find out which certificate is missing exactly? And once identified is it a case of adding it to the profile used during compilation to fix this? Ancillary question: why does the embedded.mobileprovision file contain so many certificates, and how does xcodebuild decide which ones it includes there?

Application hanging indefinitely after successful notarization
Hi, I have an app built in Unity that I am trying to sign an notarize for distribution. I can successfully codesign the app and it runs properly. But after successfully notarizing the app, the app stops opening. My process is as follows: # codesign the app. omitting "--deep" "--option runtime" or both will result in notarization failing codesign --force --deep --verify --verbose --option runtime --sign "Developer ID Application: ORG NAME (ZZZZZZZZZ)" path/to/app.app # create notarization submission zip /usr/bin/ditto -c -k --keepParent path/to/app.app path/to/app.zip # submit for notarization xcrun notarytool submit --wait path/to/app.zip -v --apple-id apple@id.com --password "aaaa-aaaa-aaaa-aaaa" --team-id "ZZZZZZZZZ" Notarization seems to succeed. Running: spctl -a -vvv -t install path/to/app.app -returns: path/to/app.app: accepted source=Notarized Developer ID origin=Developer ID Application: JOHN DOE (ZZZZZZZZZ) The Problem: Before code signature, the app runs normally After code signature, the app runs normally After notarization, the app hangs indefinitely on opening. It stays in the Dock until force quit. The app does not create its main window. There are no Gatekeeper warnings or pop-up windows. Additional Information: The second time I attempt to open the application I get a pop-up warning me that the app was force-quit while opening windows. This happens whether or not I have used xcrun stapler to staple the notarization to the app This happens whether I run the app from the terminal, by double clicking on the .app package, or by running the Unix Executable within Contents/MacOS/ Any idea how I can debug this and figure out what's going wrong? Any help would be greatly appreciated.

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.
