IOS 18.3.2(22D82) Enterprise signature installation package crashes
Recently, we have encountered some users who have been unable to open the enterprise signature application after upgrading to version 18.3.2, without an IPS file. Through system logs, we found that signature verification has occurred SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-50 "rsa_pub_crypt failed, ccerr=-7" UserInfo={numberOfErrorsDeep=0, NSDescription=rsa_pub_crypt failed, ccerr=-7} Waiting for the information, I will provide the obtained system logs below. The application package name that crashed is com. mobile. moonew

Enterprise App Crashes on Launch on iOS 18.3.2
We have an office application used internally within our enterprise. The Provisioning Profiles (PP) for the app were about to expire, so we updated the PP and released a new version. However, we've encountered an issue where some users did not update their phones in time. After the app expired, they found it unusable and downloaded the new version, but the newly downloaded app also crashes on launch. Restarting the phone does not resolve the issue, and this primarily occurs on iOS 18.3.2. What could be the cause of this problem, and how should we address it?

Apps and Books for Organizations API – Reliability Issues, Feature Request, and Rate Limit Clarification
Hi Apple team and community, We’re currently integrating with the Apps and Books for Organizations API as part of our device management solution and would like to highlight a few critical points we've encountered — including a reliability issue, an enhancement suggestion, and a request for clarification on API rate limits. 1. Issue: Intermittent 403 Errors with stoken-authenticated-apps Endpoint We are encountering intermittent 403 Forbidden responses from the stoken-authenticated-apps endpoint. Approximately 30–35% of the requests fail with a 403 status code. These failures are inconsistent — the same request (using the same Content Token and Storefront) may succeed upon retry. All requests are properly authenticated and include the required Cookie and other headers as specified in the API documentation. This issue is impacting our ability to reliably fetch app metadata at scale, particularly in workflows. We’d like to know: Is this a known issue? Could it be due to a rate limit or token misconfiguration? Are any changes required on our end to avoid these failures? 2. Enhancement Request: Include externalVersionId in versionHistory Response The versionHistory extension currently returns: versionString releaseNotes releaseDate However, for Declarative Device Management (DDM) workflows such as App Pinning, we need the externalVersionId as well. Without it, we can't reliably correlate version metadata with the specific version ID required for pinning. Adding externalVersionId would: Enable precise version targeting during App Pinning Improve reliability and automation in managed deployments We request that Apple consider including externalVersionId in the versionHistory response to better support DDM-based app lifecycle management. 3. Rate Limit Clarification We found the following note in the Apps and Books for Organizations API documentation: "The Apps and Books for Organizations API limits the number of requests your app can make using a developer token within a specific period of time. If you exceed this limit, you’ll temporarily receive 429 Too Many Requests error responses for requests that use the token. This error resolves itself shortly after the request rate has reduced." While this confirms that a rate limit is enforced, there is no detailed information about the thresholds — such as the number of allowed requests per minute, hour, or day per developer token. To help us implement proper throttling and retry strategies, we request clarification on the following: What is the exact rate limit threshold per developer token? Are there per-endpoint limits, or is it a global cap for all requests using the token? Does the API return a Retry-After header when the limit is exceeded? What is the recommended backoff strategy for clients to follow when receiving 429 errors? This information would help us implement efficient throttling and error handling logic. Any insights from the Apple team or other developers who’ve encountered these issues would be greatly appreciated!

How to install a configuration profile created through Apple Configurator or imazing profile editor on an unsupervised iPhone?
I have created a configuration profile which basically just turns off notifications for Shortcuts app but I am unable to install it on my iPhone as I am getting the following error “This profile can be installed on a supervised device only” can someone please help me with this? Would also appreciate if you have another way to turn off shortcuts notifications permanently since when I turn it off via screen time it keeps turning itself ON every couple of days.

macOS ACME certificate not appearing in System Keychain
Finally got to the stage where the ACME certificate profile is successfully installed. However, the public key/certificate itself isn't appearing in the System Keychain. I'm not sure if this is normal or if it's an indication that something went wrong after the profile installation. Unfortunately, I didn't study the log detail at the time and I'm uncertain of how to retrieve those logs from two days ago for the ACME activities. Can anyone confirm that macOS 26 should be storing ACME-retrieved MDM profile-based certificates in the System Keychain? If they should be there, what can possibly go wrong? The most obvious issue I can see is that the ACME server has requested the certificate with two CN's, which comes from the MDM profile asking for the subject against CN and the OID (2.5.4.3). Both CN's are identical. I'm surprised the profile installed if something is wrong. At first, I assumed Apple had decided to stop installing the certificates into the System Keychain.

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!

Unable to get inbound and outbound byte count in Content Filter report.
Hello, I am building a Content Filter app for iOS and would like to get access to some information about network connections that are happening on the device. I managed to have the handle(_ report: NEFilterReport) method of my NEFilterControlProvider called, but the bytesOutboundCount and bytesInboundCount properties of the report are always 0. How can I have the real byte count of the connection ?

Return to Service with App Preservation - Missing "Get Bootstrap Token" Request
Hello Apple Developer Community, I am implementing the "Return to Service" feature with app preservation in our MDM solution (iOS 26+). My goal is to use the EraseDeviceCommand to securely erase user data while preserving managed apps, and then have the device automatically re-enroll without user interaction. What I am doing: The device is supervised and successfully enrolled in Automated Device Enrollment (ADE). The device has generated and escrowed a bootstrap token to our MDM server (SetBootstrapToken received). I am sending the EraseDeviceCommand to the device via MDM with the necessary parameters for Return to Service with app preservation. The command payload includes: Enabled: true The previously escrowed BootstrapToken (as Base64 data). WiFiProfileData (as Base64 data) to ensure connectivity post-erase. Example Payload Structure (Simplified): <key>ReturnToService</key> <dict> <key>Enabled</key> <true/> <key>BootstrapToken</key> <data>YOUR_BASE64_TOKEN</data> <key>WiFiProfileData</key> <data>YOUR_BASE64_WIFI_PROFILE</data> </dict> The observed behavior: The erase command is successful. The device performs the secure user data erase. Crucially, the managed applications are preserved and automatically installed again after the reboot (confirming app preservation is working). The device connects to the Wi-Fi network successfully. The issue: I am not seeing the GetBootstrapToken request from the device hit our MDM server's check-in URL during the post-erase setup assistant phase. The re-enrollment seems to complete, but this specific request is missing from our server logs. My questions: Is the GetBootstrapToken request an explicit check-in message type, or is it an implicit part of the general CheckIn process during ADE re-enrollment when the token is used? If the device successfully re-enrolls and preserves apps, is the explicit GetBootstrapToken request still expected? Or does the token included in the EraseDeviceCommand payload satisfy all authentication needs for this workflow? What specific conditions or capabilities on the MDM server side might prevent the device from sending this specific request, even if the overall process succeeds? Any insights from Apple engineers or other developers who have successfully implemented this flow would be greatly appreciated. Thank you!

Restrict user from potentially editing a supervised device through Apple Configurator
Is there a way to restrict an end user from potentially editing a supervised device through Apple Configurator? It seems that Apple Configurator allows to make undesirable changes to a supervised device, like removing profiles, which would in turn be detrimental to the intended experience on the device, if a user would actually be able to perform such changes.

All is inhouse distributions apps stopped working after upgrading to version 18.2.1
The issue is with all our enterprise apps. All apps worked on version 18.1. For the few users that updated to 18.2.1 it stopped working after the update. I have a phone that had 18.2.1 installed before I added any enterprise apps, they work fine. So the issue is you have enterprise apps, update from 18.1 to 18.2.1 they stop working. Removing the app (and trust), and installing again doesn't solve the issue. On the app reinstall it's doesn't ask to add the trust or reboot, but the trust is added back. When running the app, it opens for a second or two, then closes.

iOS 18.5 MDM Screen Lock
Hello, I am running into a bit of an issue with the Screen Timeout/Screen Lock setting and would like some clarification on. First for a bit of context, I am enrolling personal iOS devices 18.0+ into the company MDM (Intune) with Account Driven User Enrollment. We are trying to set a screen timeout of 5 minutes and immediately after it asks for the passcode on the device, though this setting is not being applied and the device timeout setting can be set as "Never" on the user's end. This is a big security risk for the company I work for and and the issue with being HIPAA compliant. According to the Microsoft Intune Support, "In iOS 18, when using Account-Driven User Enrollment for BYOD (Bring Your Own Device) scenarios, the screen lock timeout setting is indeed marked as “Not Applicable”. This is because Apple’s privacy-preserving model for personal devices restricts administrative control over system-level settings like screen lock or idle timeout." I am needing clarification on the item mentioned from Microsoft Intune Support and if this setting is no longer able to be applied from the MDM with devices enrolled with Account Driven User Enrollment?

Documented future changes to device management
I recently reviewed the device management restrictions page of the developer docs (https://developer.apple.com/documentation/devicemanagement/restrictions) and noticed that several items are now marked "In a future release, this restriction will begin requiring supervision." Some of these changes are likely to have a dramatic impact on our app and business! So my question is threefold: a) where can I find out or request more information about the planned changes (e.g. timeline would be especially helpful)? b) why are these changes being implemented at all? c) to whom / where can I protest these changes (aside from this forum and feedback assistant)?

Return to Service with App Preservation issue
We are implementing the Return to Service (RTS) with App Preservation flow. During testing, we were able to successfully fetch the Bootstrap Token as part of the ADE enrollment process. However, when attempting to initiate the Return to Service command with App Preservation enabled, the following error was returned: [ { "ErrorCode": 12089, "ErrorDomain": "MDMErrorDomain", "LocalizedDescription": "Could not erase device.", "USEnglishDescription": "Could not erase device." }, { "ErrorCode": 66002, "ErrorDomain": "MDMBootstrapTokenErrorDomain", "LocalizedDescription": "Failed to generate LAContext for bootstrap token", "USEnglishDescription": "Failed to generate LAContext for bootstrap token" } ] Below is the sample request (with dummy data). The actual request contained valid values in all fields: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Command</key> <dict> <key>RequestType</key> <string>EraseDevice</string> <key>ReturnToService</key> <dict> <key>Enabled</key> <true /> <key>WiFiProfileData</key> <data>WiFiProfileData</data> <key>BootstrapToken</key> <data>BootstrapTokenValue</data> <key>MDMProfileData</key> <data>MDM Profile Data</data> </dict> </dict> <key>CommandUUID</key> <string>3670</string> </dict> </plist>
