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.

I am working on a security research project on macOS (Apple Silicon M5) and trying to use Memory Integrity Enforcement (MIE) to detect heap memory bugs such as use-after-free. I can confirm the hardware supports MTE hw.optional.arm.FEAT_MTE: 1) and the stack sanitizer (-fsanitize=memtag-stack) does work correctly on this machine. The gap is specifically heap tagging through the allocator. Is there any env variables for this?

Hello, I am trying to enroll in the Apple Developer Program, but I cannot complete the payment. During the purchase process, I receive the following error: We are unable to complete your order. There was an issue when we processed your order. An invalid value '1549' was provided for State, Province, or Region. My details: Country: Kosovo State/Province/Region: Kosovo Region (selected from the available option) I have verified my information multiple times, but the error appears every time. I have contacted Apple Developer Support multiple times over the past month.I have not received any response (positive or negative). I need to complete enrollment to publish my apps, and this delay is blocking my work.

I’m looking for advice from anyone who has gone through the process of converting an Apple Developer account to an Organization / Company account. I’ve been trying to convert my account for organization and the process has been taking much longer than expected. Apple initially requested documentation to verify both the business and my authority to act on behalf of the company. So far, I have already provided or prepared everything they ask for. At this point, I’ve been waiting for 9 days without much clarity on whether my documents are sufficient

I’m building an iOS app where real money moves based on goal completion results, including transfers between users. I need a real money flow that supports top ups, internal balance updates, and withdrawals. I’m launching in the EU first and want to avoid building the wrong architecture from the start. I’d appreciate practical guidance from anyone who has shipped similar apps: When can external payment processors be used for real money flows? If users can withdraw real money, what compliance requirements are usually needed first? Is it as complicated as I think? This is my first project of this kind, so I want to approach it correctly. Thank you in advance.

I develop and build the DeepSkyStacker application on an M4 Mac Mini. A user reports that with a given set of data files and application settings, that it crashes on his M4 MAX. He sent me his data files, and I can't provoke a crash on my M4. He also sent an App Crash report file which I attach. Any insight into the likely cause of the problem will be appreciated (yes, I know it is a segfault in code called from Avx256Stacking::pixelPartitioning - probably a lambda ...). dss-6.1.3-crash.log

We are experiencing an issue with ADCertificate auto-renewal on macOS devices enrolled via MDM. Platform: macOS CA: Microsoft AD CS Payload Type: com.apple.ADCertificate.managed Initial certificate enrollment works correctly EnableAutoRenewal is set to true Certificate does not renew automatically as it approaches expiry We would like to confirm: Are there any known issues with macOS ADCertificate managed payload auto-renewal, particularly with Microsoft AD CS environments? Below is the exact payload configuration in use: Thank you.

I would like to avoid the middle man and call Objective C directly from C Currently I do this This is called from a dispatch table in a pure C file _ctx->mt_render_funcs.mtlEnd(_ctx); Which calls this routine in a obj c file .m void mtlEnd(MTRenderContext mt_ctx) { // Call the Objective-C method using Objective-C syntax [(__bridge id) mt_ctx->mt_render_funcs.mtlObj mtlEnd]; } Which ends up here... in ObjC #pragma mark mtlEnd (void)mtlEnd { // vertex buffer size_t size; size = sizeof(Vertex4ColorNormalTex) * _ctx->vert_eng.current_vertex; [_currentRenderEncoder setVertexBytes:_ctx->vert_eng.vertices length: size atIndex: VertexInputIndexVertices]; [_currentRenderEncoder drawPrimitives:(MTLPrimitiveType)_ctx->vert_eng.prim_type vertexStart:0 vertexCount:_ctx->vert_eng.current_vertex]; } It would simplify this to get rid of one call and call ObjC directly. The other idea is I want to use GCD and put a lock / unlock on the call from C to ensure thread safety so I can use GCD to dispatch a thread to do the ObjC routines. I want to stick with C as the foundation so it can be used directly from C or a FFI interface from other languages. But Metal works well in ObjC and I would prefer to use that. Thanks ahead of time.

Hardware: • Mac Studio (M1 Ultra) • Apple Silicon • Sufficient free disk space (~35GB+ available) • SIP enabled • 4 local Time Machine snapshots present Current System: • Already running macOS Tahoe beta • Attempting upgrade to macOS Tahoe 26.4 Beta (Build 25E5207k) Primary Issue: Software Update downloads successfully, then moves to “Preparing…”. It stalls at “About 5 minutes remaining” for ~10–15 minutes and fails with: “Failed to prepare the software update. Please try again. An error occurred while downloading the selected updates.” The error appears network-related, but download always completes. Observed Behaviour: • “Checking for Updates” completes in <3 minutes. • softwareupdated and mobileassetd CPU usage <1%. • softwareupdate --history shows no record of the failed beta install. • No excessive system load or obvious disk pressure. Steps Already Attempted: 1. Standard Software Update retries • Multiple download/retry cycles from System Settings. • Same Preparing failure every time. 2. Permissions / Disk Access • Granted Terminal Full Disk Access. • SIP remains enabled. • Some system-protected locations still return “Operation not permitted”. 3. Cache / State Cleanup Attempts • Removed /Library/Updates/*. • Cleared temporary softwareupdate folders under /private/var/tmp. • Attempted MobileAsset cache cleanup where permitted. • Killed softwareupdated and mobileassetd processes (auto-restarted by launchd). 4. Beta Channel Reset • Turned Beta Updates OFF in System Settings. • Rebooted. • Re-enabled Beta Updates. • Forced catalog refresh via softwareupdate -l. 5. Snapshot Check • tmutil listlocalsnapshots / shows only 4 snapshots (normal range). 6. Full Installer Workaround softwareupdate --list-full-installers shows: • macOS Tahoe Beta 26.4 (25E5207k) • Tahoe 26.3 / 26.2 / 26.1 • Sequoia / Sonoma / Ventura / Monterey installers Downloaded installer via: softwareupdate –fetch-full-installer –full-installer-version 26.4 Installer downloaded correctly: /Applications/Install macOS Tahoe Beta.app 7. startosinstall Method (Apple Silicon optimized) Attempted install with: sudo “/Applications/Install macOS Tahoe Beta.app/Contents/Resources/startosinstall” –user –agreetolicense –nointeraction –forcequitapps –rebootdelay 30 –passprompt Authorization succeeds, installer begins preparing, but installation still ultimately fails. Additional Notes: • CPU usage remains low during failure. • No excessive snapshot count. • Error messaging consistently references download/network even though download completes. • Issue appears to occur during cryptex/asset preparation phase rather than initial download. Question for Apple / other developers: Has anyone else seen Tahoe 26.4 beta fail specifically during the Preparing phase on Apple Silicon (especially Ultra-class chips)? Looking for confirmation whether this is a known MobileAsset or cryptex staging issue, or if logs indicate a deeper APFS / volume-owner authorization problem.

Has anyone been able to raise a ticket with the support team in the past 48 hours without getting an infinite loader or error on the page?

Leider ist bei der Beta 2 iOS 26.4 immer noch so das dass öffnen der App Store sehr langsam ist und teilweise sehr lange braucht bei suchen von Apps.

I installed the new 26.4 ios and now can't compose or reply to emails on the Gmail app. I tried restarting my phone and uninstalling and reinstalling the app, but nothing helps. How can I fix this?

Has anyone gotten Postgres to run in a sandboxed app? I am compiling Postgres 18 myself from source and have tried to patch it so it doesn't use sysv (shmem) but it apparently has all kinds of invocations of sysv and once it's sandboxed has issues, e.g.: 2026-02-24 18:26:05.014 EST [4384] FATAL: semctl(65596, 16, SETVAL, 536) failed: Operation not permitted Does anyone know of a way to either make the sandbox relax or make Postgres compatible with sandboxing? I have tried passing flags to initdb to use POSIX semaphores but it always wants to use sysv so I'm finding myself super deep in the weeds of the Postgres source code.

Hi everyone, I’m considering integrating External Payments into my iOS app. I’ve done some research, but I’m finding it difficult to pinpoint the exact commission rates for different regions. For those of you who have already implemented external payment links: Could you share what the actual fees paid to Apple look like in your specific Geos (e.g., US, EU, or others)? Does the total cost—including Apple's commission and the payment processor's fee (like Stripe)—end up being significantly lower than the standard 15-30% IAP?

Updated iOS to 26.4. Gmail folders have disappeared in Apple Mail. Can‘t transfer email messages to folders as consequence. Any ideas?

After updating to another beta of High Sierra, my internal hard drive became read-only somehow. I have a user home directory on that and many things have stopped working. I tried re-installing the OS, but it didn't help. I'm out of options by now. Anyone has ideas how can I fix that?

I am verifying my new account. However in my first log in it says my account is locked. When I try to get a new password, it is now showing a different phone number to verify that isn't mine. Now I am stuck in the loop where I can't contact support as Apple doesn't share support email or phone number details unless you log in, so now I'm stuck in a loop. Any help Apple Support, can you send me your email?

Is there any way to get the "uninstall" status to run code while uninstalling an app?

Hi everyone, I’m having issues registering my own Apple Developer accounts in both China and the US. For my China account, my Face ID is already in use by accounts registered under two companies, which prevents me from creating a new developer account. For my US account, my device SSID and handheld ID documents were used, and Apple Support advised that I can only register using a US identity. I’ve already contacted Apple Support, but the problem remains unresolved. I’m looking for shared experiences or advice on how to handle this situation. Thank you in advance!

I recently updated my iphone 14 from IOS 26.4 public beta to 26.4 developer beta 1 and I have noticed that whenever I am connecting apple original charger along with original lightening cable, the phone is charging at a very slow speed and the lock screen shows “slow charger” prompt, I tried cleaning the cable connector and also made sure that the lightening port is clean still the issue persist. Need Apple to solve this issue for multiple users like me which I have noticed on reddit with the same problem.
