Unacceptable, Dangerous Bugs with VPN configuration profiles.
I'm trying to set up a configuration profile on a supervised device for a kid's phone. I want to force a VPN 100% of the time except for local network activity and some specific domains. Or at the very least, have a few apps go outside the tunnel. Apple makes this IMPOSSIBLE even though according to the documentation it should be possible. The IKEv2 vpntype has a key "OnDemandUserOverrideDisabled" which is supposed to prevent a user from toggling off the vpn, which obviously defeats the purpose of having it. However, as other users have posted, this DOES NOT WORK. So anyone can just turn off the vpn and be connected to the internet unprotected. On the "AlwaysOn" vpntype, the element "ApplicationExceptions" which would allow you to list a few applications that can go outside the tunnel DOES NOT WORK. This is critical because so many domains automatically block vpn servers and it's a huge pain. Also local network activity also gets blocked, which makes it impossible to connect to local devices. And there's no split tunneling possible with this vpntype. So basically, it's impossible. I WOULDN'T BE SURPRISED IF APPLE DID THIS INTENTIONALLY TO KEEP KIDS ADDICTED AND IN DANGER SO THEY USE THE PHONE MORE.

Managed device attesation fresh certificate expectancy duration
When a DeviceInformation command along with ManagedAttestion data in the query along with a new nonce and after 7 days last time we queried for fresh certificate, is there a possibility that a) we will get a DeviceInformation response without a Managed attestion certificte. OR b) We will get a cached certificate Also, what's the average increase in expected response time when we query Managed attestation certificate in DeviceInformation.

How to get hardware information for Managed device attestation querying for iphone, ipad and AppleTv
Here https://github.com/apple/device-management/blobelease/mdm/commands/information.device.yaml#L3246 it is mentioned that for querying Managed attestation certificate the ios device needs to have A11 Bionic and later, Wanted to understand how to get this information programmatically i.e is Apple sending chip information for iphone and ipad devices as part of some sample ? or is there a way to query this information from the device ? Here https://github.com/apple/device-management/blobelease/mdm/commands/information.device.yaml#L3246 it is mentioned that for querying Managed attestation certificate the macos device needs to have Apple Silicon, using IsAppleSilicon https://github.com/apple/device-management/blobelease/mdm/commands/information.device.yaml#L357 property is fine ? Can we use this field to determine if the device is Apple silicon ? Same question for Apple TV as well - How to get the information if a device is having A12 Bionic and later ? and same for Apple watch, how to know if a device is S4 and later ?

About the Declarative Device Management Activation Update
Hi everyone, We are currently integrating Apple DDM into our existing MDM system and encountered an issue where an update to a declaration failed with the message: "Activation xxxxx is missing configurations." While we know how to fix the issue, I'm quite concerned about potential impacts. An incorrect activation could deactivate the current one, leading to the automatic removal of all profiles and apps. Given that unexpected server errors can occasionally occur, this could significantly impact end-users if their apps are suddenly removed. I'm looking for a way to prevent activations from "failing to update then lost everything" or a safer method to deploy updated version of activations, especially given the potential for unexpected server errors or logic bugs. This could significantly affect end-users if their apps suddenly disappear. If anyone has any insights, thoughts, or best practices to share regarding activation updates, I would greatly appreciate your input. Leo Chan

iOS 18 - Inquiry regarding issues related to camera control settings when using the MDM blocking function
I would like to contact about an issue with the iOS 18 update. With the release of the new iPhone 16, camera controls have been added. however, when using MDM, there is an issue where the camera control button settings change after blocking and unblocking the camera. 1. If the camera control button is originally set to 'Camera', when you block and unblock the camera through MDM, the button setting changes to 'None'. Shouldn't the camera control settings be maintained even after blocking and unblocking the camera? If this is a known issue, can you tell me when it will be fixed and updated?

mobileconfig: OnDemandRules URLStringProbe doesn’t work in DNSSettings for iOS 18
Opening a fresh post as the other seem old/abandoned. I’m trying to add a fail-safe URLprobe to DNS setting profile (DNS over http) for the case that the iPhone/iPad connects to a wifi hotspot with captive portal without internet access. I use OnDemandRules to circumvent known problematic SSID names a specific (wildcard) domains - both working just fine and the requests are falling-back to a system resolver for such a requests. I’ve added a URLStringProbe which supposed to check availability of the internet. The probe should trigger on 200 OK response code and use the DNSSettings or fallback to a system resolver in the case of any other outcome, according to the documentation: A URL to probe. If this URL is successfully fetched (returning a 200 HTTP status code) without redirection, this rule matches. https://developer.apple.com/documentation/devicemanagement/dnssettings/ondemandruleselement https://developer.apple.com/business/documentation/Configuration-Profile-Reference.pdf Tested on iPhone 14 (iOS 18.1) but it doesn’t work. I’m using Clouflare https://1.1.1.1/index.html for the sake of simplicity and do some adjustment in IP/path for testing purposes using https to enforce TLS (to avoid hijack/MitM from a captive portal) using a direct IP (in this case Cloudflare) so I don't need to resolve a domain to execute the probe itself Anyway, I’ve changed the URL for a testing purposes to return either 404, redirect or timeout and in all cases cases the probe acts the same way like for 200 OK response. My expectation is that probe should test negative and go to next rule which is <key>Action</key> <string>Disconnect</string> and thus use the system resolver which will allow the system to detect a captive portal and display sign-in popup to the captive portal Any idea where might be the issue? Example 1 - with all rules <key>DNSSettings</key> <dict> <key>DNSProtocol</key> <string>HTTPS</string> <key>ServerURL</key> <string>https://dnsserverexample.com/v1/something/id/dns-query</string> <key>ServerAddresses</key> <array/> <key>SupplementalMatchDomains</key> <array/> </dict> <key>ProhibitDisablement</key> <true/> <key>OnDemandRules</key> <array> <dict> <key>Action</key> <string>Disconnect</string> <key>SSIDMatch</key> <array> <string>whitelistedSSID1</string> <string>whitelistedSSID1</string> </array> </dict> <dict> <key>Action</key> <string>EvaluateConnection</string> <key>ActionParameters</key> <array> <dict> <key>DomainAction</key> <string>NeverConnect</string> <key>Domains</key> <array> <string>*.whitelisteddomainexample.com</string> <string>*.whitelisteddomainexample2.com</string> </array> </dict> </array> </dict> <dict> <key>URLStringProbe</key> <string>https://1.1.1.1/index.html</string> <key>Action</key> <string>Connect</string> </dict> <dict> <key>Action</key> <string>Disconnect</string> </dict> </array> </dict> Example 2 - just URL probe and fail-open for iphone <key>DNSSettings</key> <dict> <key>DNSProtocol</key> <string>HTTPS</string> <key>ServerURL</key> <string>https://dnsserverexample.com/v1/something/id/dns-query</string> <key>ServerAddresses</key> <array/> <key>SupplementalMatchDomains</key> <array/> </dict> <key>ProhibitDisablement</key> <true/> <key>OnDemandRules</key> <array> <dict> <key>URLStringProbe</key> <string>https://1.1.1.1/index.html</string> <key>Action</key> <string>Connect</string> </dict> <dict> <key>Action</key> <string>Disconnect</string> </dict> </array> Also I’ve tried to debug similar issue in the past on MacOS. I’ve tried to add debug profiles NetworkDiagnostic.mobileconfig and mDNSResponder.mobileconfig but I don't see any logs related to OnDemandRules processing - any clue how to get some insight into the rules processing/evaluation?

Certain profiles can't be removed via Apple Configurator
I currently have a bunch of profiles that cannot be removed whatsoever. iOS 18.0 (22A3354), Apple Configurator Version 2.17 (9A15) (happens in the stable configurator version, too) On trying to remove the profiles via Apple Configurator, I get the error message The profile “[profile name]” does not have the expected certificate for removal. [DMCInstallationErrorDomain – 0xFA8 (4008)] The problem with that is, The profile was installed a day ago using the exact same MacBook that I now try to remove it. Nothing has changed. The profile was signed, but it's signed with the same Supervision Identity that I now still have in Apple Configurator. The SHA256 fingerprint I see inside iOS matches the one I see on macOS in the Configurator in the "Show Supervision Identity..." section. So there should be absolutely no reason why the profile removal fails. I'm not entirely sure if this is relevant, but the affected profile's PayloadIdentifier has an at-sign in it. The docs say this is supposed to be A reverse-DNS style identifier (com.example.myprofile, for example) that identifies the profile so an at-sign might not be valid - but the UI in the Configurator does not have an issue with it. The only way to get rid of these profiles appears to be a full wipe, which is what I'll do soon. If there is any information I can provide before the wipe (or a better channel to report this on), I'm happy to.

iOS VPN kill switch or force VPN
I'm interesting to use network (and internet too) access on iPhone only through pre-configured (by corporate profile) VPN connection. If the VPN connection is unavailable for some reason then network must to be unaccessable. Which ways I have to solve my problem? I need to use some 3rd party software or it can be solved by MDM Profile? Best regards, Grigoriy.

The app packaged with the enterprise certificate on the iPhone 16 crashes.
The original text is in Chinese, and below is the content translated using OpenAI. 問題描述: 因為一些因素,所以公司申請了兩個企業憑證,其中Entity Name一樣,但Team ID不一樣。現在發現iPhone16系列裝置的使用者,無法同時使用兩個憑證打包出來的APP,不是都會閃退就是其中一個會閃退。 重現問題的逐步說明: 測試的情況有兩種: 從iPhone16之前的裝置轉移資料到iPhone16,這兩個APP打開都會閃退 直接在iPhone16安裝這兩個APP,則第一個安裝的APP可以正常使用,第二個安裝的APP會閃退。如果想要切換能使用的APP,需要到 一般-VPN與裝置管理-INNOLUX CORPORATION ,點擊”刪除App”,然後更換安裝順序。 如果是舊裝置升級到iOS 18,則不會有該問題 期望的結果: 兩個APP都能正常使用 實際看到的結果: 如果是舊裝置移轉資料到iPhone16,則都會閃退:如果是直接在iPhone16安裝這兩個APP,則第一個安裝的APP可以正常使用,第二個安裝的APP會閃退。 OpenAI Translation: Problem Description: Due to certain factors, the company applied for two enterprise certificates, which have the same Entity Name but different Team IDs. It has now been discovered that users of the iPhone 16 series devices are unable to use apps packaged with both certificates simultaneously; either both apps crash or one of them crashes. Step-by-Step Reproduction of the Issue: There are two testing scenarios: Transferring data from a device prior to the iPhone 16 to the iPhone 16 results in both apps crashing upon opening. Directly installing both apps on the iPhone 16 allows the first installed app to function normally, while the second installed app crashes. To switch to the functioning app, one must go to Settings - VPN & Device Management - INNOLUX CORPORATION, click "Delete App," and then change the installation order. If an older device is upgraded to iOS 18, this issue does not occur. Expected Result: Both apps should function normally. Actual Observed Result: If data is transferred from an older device to the iPhone 16, both apps crash. If both apps are directly installed on the iPhone 16, the first installed app works normally while the second installed app crashes.

Missing iOS MDM Restriction for App Hiding/Locking
On the "What's new for enterprise in iOS 18" page here: https://support.apple.com/en-am/121158, one of the new features mentioned is: "On supervised devices, organizations can disable a user’s ability to hide and lock apps." Despite reviewing the developer documentation surrounding device management (https://developer.apple.com/documentation/devicemanagement), as well as going through the latest changes to schema definitions (https://github.com/apple/device-management), I have been unable to find a restriction that corresponds to this functionality. This is a feature that I'd like to implement, has anyone found any details about this restriction and what key may need to be inserted in the restrictions payload to use it?
