We're sending the spcData payload to our fairplay key server (version 5.1) with the base64 encoded string of our fairPlay.cer that was downloaded from our developer portal and we're getting a spcVersionErr (-42580) for the spc version. The value that is being received by the key server seems to be 813827283 when it should be either 1 (base_constants.SPCVersion.v1.rawValue) or 2 (base_constant.SPCVersion.v2.rawValue). We're assuming we're encoding the fairplay.cer incorrectly. Any insight from anybody would be appreciated.

Curious what backend others are choosing these days. I am building a vocabulary app and exploring which backend would be a good fit. Considering options like CloudKit, Firebase, Supabase, AWS Amplify, custom servers, or a combination. What are you using and what made you choose it?

Good morning, Apple devs. I'm looking for resources and help designing a BLE hardware peripheral that is compatible with iOS and iPad. I've seen the MFi program, but I've also seen plenty of peripheral devices that work with iOS and iPad that are not listed in the MFi compatibility lists. Can anyone refer me to the proper channels to get support for development of a hardware device? Thank you.

I recently got a new iPhone for my mom so that she could have Assistive Access due to her declining cognitive health. I selected the family members she calls the most as her favorites, but when attempting to call some of said family members (myself included), nothing happens. It works for about half the contacts, and not for the other half. I’m her main caregiver so it’s pretty ironic that I’m one of the ones it doesn’t work with. I’ve tried exiting and re-entering Assistive Access, deleting and re-adding all the contacts, restarting the phone, force-restarting the phone, and checking if the iOS is the most recent update (it is). Nothing works. Please help.

We are developing a platform (Ferve) where users subscribe to individual artists to access exclusive content. We use a user-centric remuneration model: each artist has an independent income pool, and funds from a specific subscription must be attributed solely to that artist. We have two critical challenges regarding our integration: Granular Financial Reporting for User-Centric Payouts As the Merchant of Record, Apple provides aggregate Financial Reports. However, these reports do not provide a breakdown of taxes, commissions, or exact exchange rates used for individual transactionId records. Though we can keep records of each transaction in our database, thus linking them with which artist they belong to, we are unable to collect fees/taxes applied to each individual transaction. Because our payouts are artist-specific, we need to deduct the exact regional taxes and Apple commissions from each transaction to calculate the artist's due balance. Currently, we can only see the final consolidated balance in BRL (Brazilian Reals) at the end of the month. Is there an API or report that provides the net proceeds and tax breakdown per transaction ID? How can we retrieve the exact exchange rate applied to foreign currency sales (e.g., EUR to BRL) before the final consolidation? Supporting Multiple Concurrent Subscriptions Our current App Store Connect configuration uses a single 'Subscription Group' for all artist 'Clubs' since they share the same price points. However, we have found that users cannot subscribe to more than one product within the same group simultaneously (the App Store treats this as an upgrade/downgrade). On our platform, a user must be able to subscribe to Artist A and Artist B at the same time. What is the recommended architecture for this? Should we dynamically create a unique Subscription Group for every artist onboarded to our platform? If we use unique groups, is there a limit to the number of Subscription Groups one app can have? We appreciate the help, Ferve

I would like to know if this problem only affects me or others as well. Since the latest version of iPadOS, my eSIM no longer works, or rather, I have no mobile data. It worked with the previous version, but since I updated, mobile data (Internet) no longer works. When I open Safari, the window " Mobile data network could not be activated. You do not have a mobile data plan. Use Wi-Fi or open the mobile data options in "Settings". Any Recommendations? Thank you all

Problems searching in mail after upgrade to Tahoe 26.4 Beta (25E5218f). Removing the index files and requesting rebuild results in a hung rebuild process. In the activity monitor I see Indexing... and a bar that is stuck at 0%. I have rebooted and restarted mail. No change. I was able to rebuild the spotlight search, and it is working properly.

Users report being able to log-in on the website and everywhere else, using google sign-in credentials, just not working on the app.

I dutifully upgraded my software (beta) on Feb. 24 when prompted. I could not get the computer to reboot, then after about 5 hours on the phone with, I think, 4 techs, they told me the only solution was to wait for the next update - I could not go backwards to the regular version. So $1,299 later I have a new Mac Mini M4! I have to work, so it was the only solution. What do I win?

I installed the latest build of Tahoe (25E5218f) yesterday on our test machine, an M1 Pro MacBook Pro and have been having a hard time getting my WiFi network to work. It's especially noticeable in Mail and Safari. Mail shows it can't connect to the designated server, and Safari simply can't connect to most sites. None of my other devices or computers are having problems, so I have to assume it's this last build that is the culprit. When I tether to my iPhone Air, everything pops back into place and I can access Mail and use Safari. I've reported the problem with FBA, but wanted to know if anyone else is experiencing the same thing.

Environment: Device: MacBook Pro (Mac16,7) Chip: M4 Pro (SoC ID 6040, Revision 11) OS: macOS 15.2 (24C101) Kernel: Darwin Kernel Version 24.2.0; root:xnu-11215.61.5~2/RELEASE_ARM64_T6041 Summary: I am developing a Windows emulator on the MacBook Pro M4 Pro platform. During testing with certain applications, the system frequently triggers an instantaneous reboot. This issue appears to be highly specific to the M4 Pro hardware and current OS version. Observation & Diagnostic Challenges: Upon reboot, the system generates a bug_type 210 (SoC Watchdog Reset) report. The panic string indicates: "Unexpected SoC (system) watchdog reset occurred after panic diagnostics were completed". The primary difficulty in debugging is that the hardware reset happens so rapidly that the kernel fails to capture a stackshot or any detailed panic trace. We have practically no actionable information from the standard diagnostic reports. However, we did find the following recurring entries in the system log prior to the resets: Ignored NI0 NI0 niGeneral 1 NO_ACCESS error (0x00000010) cmd/st:0x14(ncrdincr)... srcchildid/srcparentid:0x8ea/0x1d Comparison & Testing: We have performed extensive cross-version and cross-device testing to isolate the cause: M1/M2 Series: Identical tests on M1 and M2 devices running macOS 15 do not trigger this issue. The applications run stably. OS Versions: Interestingly, this issue seems significantly harder to reproduce on newer system builds (e.g., version 26 series), suggesting it might be a regression or a specific incompatibility in the current macOS 15.2 environment for M4 Pro. Request for Assistance: Since we cannot collect stack traces through conventional means, we are seeking your expertise: Known Issues: Has Apple received similar reports from other developers working on low-level emulation or virtualization on M4 Pro? Is this a known issue in macOS 15.2 / build 24C101? Debugging Guidance: Given that the system reboots without leaving a stackshot, what are the recommended methods to capture more granular data? Are there specific boot-args or instrumentation tools that can help log the state of the SoC fabric (NI0) before the watchdog kicks in? Architectural Insights: Based on the NI0 NO_ACCESS error and srcchildid: 0x8ea, could you suggest which subsystem or memory operation we should investigate further?

Hello Apple Support, I’m experiencing an issue on the “Create Your Apple Account” page. After filling in all required information, the “Continue” button remains disabled and cannot be clicked.

Dear Apple Developer Support Team, I am writing to formally escalate an issue regarding my Apple Developer Program enrollment. On February 23rd, I completed the $100 enrollment payment for an Individual Apple Developer account. The amount has been successfully debited from my card, and I have received official payment confirmation emails from Apple confirming receipt of the funds. However, as of today (March 3rd), my account still reflects that payment needs to be completed, and the enrollment remains inactive. This is my first-time enrollment as an individual developer. Given that payment has already been processed and acknowledged by Apple, I am concerned about the lack of activation and the absence of any communication regarding the delay. Additionally, I have submitted multiple support requests over the past five days but have not received any response or update. This delay is affecting my development and release timelines. I kindly request: Immediate confirmation of payment reconciliation on your end Clarification on the current status of my enrollment An estimated timeline for activation Escalation of this case to the appropriate billing or developer enrollment team Please let me know if any further documentation (transaction ID, invoice number, Apple ID details) is required from my side. I would appreciate your urgent assistance in resolving this matter. Kind regards, Gowtham Potureddi
