One of four In House enterprise apps won't install after downloading
I appreciate any suggestions on a problem we're having. Here's what's happening: We use Visual Studio to create Xamarin and MAUI apps. We have several apps that all have In-House provisioning profiles attached to the same certificate. Developers upload ipa files to our internal website, so our QA team can install and test them. We have done this in this way for several years. As of a month or so ago, one of these apps will not install after download. Under the app icon on the device there is a download icon before the app name, and tapping the icon receives in the error message, "This app cannot be installed because its integrity could not be verified." Something else that stated around the same time is that while the name of our enterprise certificate "iPhone Distribution OurCompanyName" shows in the Signing Identity dropdown. When we select it and open the list again, the list now also has "Unknown (iPhone Distribution OurCompanyName)" as a selection. Timing can't be a coincidence. It must be connected to the problem. I have made new certificates and provisioning profiles (Ad-Hoc and In-House) several times, but nothing I have tried over the past three days has worked. And, as I mentioned, we have many other apps that work just fine.

Need status from device before wipe due to passcode policy "maxFailedAttempts" setting
Enroll an iOS device via MDM and apply passcode policy with "maxFailedAttempts" setting enabled https://developer.apple.com/documentation/devicemanagement/passcode Now when the user attempts to unlock device exceeds above "maxFailedAttempts" - the device gets wiped. Now the administrator is unaware of this event. It would be helpful to get an message/DDM status from device to notify the MDM server that device is wiped due to incorrect passcode attempts.

Error during Automated device enrollment - The cloud configuration server is unavailable. (MDMDeviceEnrollment:103)
The customer is trying to enroll macOS devices to Hexode via Apple Business Manager (without reset). Upon running the command sudo profiles renew -type enrollment, he received the below error. Error: DEP enrollment failed: The cloud configuration server is unavailable. (MDMDeviceEnrollment:103) Upon running the command sudo profiles show -type enrollment in Terminal, he received the following output. Error fetching Device Enrollment configuration: (34006) Error Domain=MCCloudConfigurationErrorDomain Code=34006 "The cloud configuration server is unavailable."

UserInfo=0x6000009f0440 (not displayed)}}}}}} The device was assigned to the Hexnode server and listed in DEP devices in Hexnode. It seems to be an Intel device and we tried following troubleshooting steps. He said another user tried out the case and was encountering the same errors. He tried the following steps as part of troubleshooting. Installed pending OS updates Re-assigned device to Hexnode server Cleared NVRAM/PRAM Switched networks Turned off firewall and proxies on the device Re-assigned DEP configuration profile to devices Re-configured DEP and APNs Enrolling the device using the enrollment URL does work and he's able to deploy actions as well. He is willing to reset the device and check as well, but he has ~30 devices in ABM that are remote and in use. Since 2 devices encountered the case, he would like to know more about what happened.

Apple Login fails with Managed Apple IDs on supervised iPhones with iOS 17.3 version
We noticed that Apple Login fails if we try to login with Managed Apple ID on iOS 17.2 & 17.3 This issue could have been introduced in iOS 17 but we did not have iOS 17.0 or 17.1 to validate this. There are few prerequisites to this: Should be a supervised device. It can be enrolled in ABM or ASM. Apple ID should be Managed Apple ID Device should have a passcode policy Device should have “allowListedAppBundleIDs” added in the “com.apple.applicationaccess” payload If either of the above conditions are not met, then the issue does not happen. If the device is set up in the above way and we try to login with Managed Apple ID, then the login fails. Please refer the recording at this link: https://drive.google.com/file/d/1XG17loAuH_GB1IyGdwD8txjkHZWqGeD1/view?usp=drive_link We reproduced the issue three times and got the log files: Issue occurred at: 21st March 2024 at 19:54:58 IST a. Log file name: sysdiagnose_2024.03.21_19-55-26+0530_iPhone-OS_iPhone_21D50(07.54.58 pm).tar.gz b.

Link: https://drive.google.com/file/d/1zlLLMd0ugJoiZtmpWlarREFDl1vjZoWP/view?usp=drive_link During the above tests, this was the setup Passcode Policy: a. requireAlphanumeric: true b. minLength: 13 c. allowSimple: false allowListedAppBundleIDs: This can be anything but atleast one of them should be enabled. For example a. com.apple.AppStore b. com.apple.MobileAddressBook c. com.apple.calculator d. com.apple.camera e. com.apple.DocumentsApp f. com.apple.facetime What results I expected: The user should be able to login without an issue What results I actually saw: The user does not login We also created a ticket in Feedback assistant in March but haven't received any response: FB13694721

Parental Content Filtering MDM Payload causes internet issues on Mac Silicon devices with OS 14 and above
Since the release of macOS 14.0, we have encountered issues with the Content Filtering MDM Payload. This problem is unusual but can be resolved by restarting the system. Prerequisites: macOS 14 or higher Any Mac with a Silicon (ARM) processor Restrictions Payload and Parental Content Filtering Payload must be installed on the device, either manually or through any MDM service Issue Details: When the Parental Content Filtering Payload is removed after installation, it causes internet issues, and browsers display "The site can't be reached". This affects applications as well, with Safari being the only application that continues to work. The issue can be resolved by either re-adding the Content Filtering Payload or restarting the Mac. Links: Restriction Payload: https://drive.google.com/file/d/1buwLFgbjTRXij9ZSv1QrDeRnWbFfKNtq/view?usp=drive_link Content Filtering Payload: https://drive.google.com/file/d/1eAJiBg4N__dML65MRDH7hYCocuTqOCcu/view?usp=drive_link System Logs: https://drive.google.com/drive/folders/1hKKNAoMn_4x1CqMTxz1bPrUucCbftjO9?usp=drive_link Screen Recording: https://drive.google.com/file/d/1uS8CJqe9p9DG9XzhUnIsY35eme4Dxs60/view?usp=drive_link

Lost access to ABM
Hi, I would like to introduce you to the problem of my client, who is probably one of the first Apple Business Manger users in Poland. The client created an ABM instance and verified it. He also created a second administrator account as recommended, and added the first device. The problem was that these accounts were accessed by one person who used Cyber Ark to save credentials. After saving the credentials for the administrator accounts, an error occurred with Cyber Ark and the passwords of these accounts were saved incorrectly. The customer has since lost access to the verified ABM instance with one device already added. Can you advise me on what to do in this situation? Can https://iforgot.apple.com/ help in any way here? Thanks a lot for all your help Best Regards, XVsorim

App Custom URL to be available only for Managed Apps
My application supports Custom URL Schema which is used to perform an open operation. My application is used as a helper app for MDM, hence it will be installed as a Managed Application. I want only the other Managed Applications to be able to invoke the Custom URL Schema and not allow it for unmanaged applications. Is there any such provision provided by Apple MDM protocol?

Bit quiet here?
I know Apple Engineers are busy and it’s just been WWDC, but things seem very quiet here. There have been 17 posts in the past 10 days and only 6 of them have any replies. It’s great that non-Apple Engineers offer advice and assistance, but I kind of thought there’d be at least a reply from an Apple Engineer to each post?

CNContact instantMessage field duplicates after serializaiton/deserialization
Hello folks, I stumbled upon a weird CNContact serialization problem. I use the Contacts framework to update the AIM field, which is one of the instantMessageAddresses within a single Contact. Here is the simplified code I used: func updateAIMFieldOn(contact: CNContact, aimValue: String) { do { guard let mutableContact = contact.mutableCopy() as? CNMutableContact else { logger.error("[CM] Couldn't update contact with aim \(aimValue)") return } var updatedAddresses = mutableContact.instantMessageAddresses updatedAddresses.append(CNLabeledValue(label: "", value: CNInstantMessageAddress(username: aimValue, service: CNInstantMessageServiceAIM))) mutableContact.instantMessageAddresses = updatedAddresses let saveRequest = CNSaveRequest() saveRequest.update(mutableContact) try CNContactStore().execute(saveRequest) logger.verbose("Contact's AIM updated successfully!") } catch { logger.error("Couldn't update contact") } } And after serializing the contact to data, and then deserializing, the contact got two AIM fields with the same value: X-AIM;type=pref:some:part:of_my_aim_value IMPP;X-SERVICE-TYPE=AIM;type=pref:some:part:of_my_aim_value Why does it work in this manner? Is it possible that ":" char causes that? Format of my aim username is {some:part:of_my_aim_value}. I didn't find any information in the docs. Thanks!
