Reply to System Panic with IOUserSCSIParallelInterfaceController during Dispatch Queue Configuration
I believe you filed a bug asking about this earlier, and I have my own bug on this (r.169737319). It fell off my radar for a bit, but I've asked the team for some guidance on the right way to handle this today. Following up on myself after talking with the team, here is how I would suggest handling this: In the first call to UserProcessBundledParallelTasks, you should: Store the OSAction you receive into your DEXTs own ivars. Intentionally retain() that OSAction. This retain will NOT be balanced, so you're intentionally over-retaining the OSAction (it will be destroyed when your DEXT is). You can actually retain it a few times if you want. On all future calls to UserProcessBundledParallelTasks, assert that the OSAction you receive is the same as the action you received in #1, intentionally crashing if it changes. Note that the point of #3 is NOT to detect a valid state you should anticipate or handle. It's purely there as an overall safety check that will either never trigger or will trigger years fr

Notarized but Gatekeeper fails macOS 15 only?
Okay, I just pushed a release and notarized. Works great on my test laptop (macOS 26.2) and my test desktop (macOS 14.x) But it seems to fail for a friend who's running macOS 15. I've been using the same GitHub actions successfully for months. How can notarization work for macOS 14 and 26, but not for macOS 15? I think everything looks okay as far as the signing? I've checked codesign -dvv Executable=/Applications/Avogadro2.app/Contents/MacOS/Avogadro2 Identifier=cc.avogadro Format=app bundle with Mach-O thin (arm64) CodeDirectory v=20500 size=11607 flags=0x10000(runtime) hashes=352+7 location=embedded Signature size=8986 Authority=Developer ID Application: Geoffrey Hutchison (…..)

All notarization submissions stuck "In Progress" — first-time notarization, 9 submissions over 16+ hours
I'm submitting my first macOS app (a native SwiftUI menu bar app, signed with Developer ID Application certificate, Hardened Runtime enabled) for notarization using xcrun notarytool submit with keychain profile authentication. All 9 of my submissions have been stuck at In Progress for up to 16 hours. None have transitioned to Accepted or Invalid. Logs are unavailable for all of them (notarytool log returns Submission log is not yet available). Environment macOS: 26.2 (25C56) Xcode: 26.1.1 (17B100) notarytool: 1.1.0 (39) App: Native SwiftUI, universal binary (x86_64 + arm64), ~2.2 MB DMG Bundle ID: com.gro.ask Team ID: 4KT56S2BX6 What I've verified Code signing is valid: $ codesign --verify --deep --strict GroAsk.app passes with no errors $ codesign -dvvv GroAsk.app Authority=Developer ID Application: Jack Wu (4KT56S2BX6) Authority=Developer ID Certification Authority Authority=Apple Root CA CodeDirectory flags=0x10000(runtime) # Hardened Runtime enabled Runtime Version=26.1.0 Format=app bundle with Mach-O uni

Reply to Error when updating system extension
[quote='875131022, IHadToChooseAUserNameAndIdidntWantTo, /thread/809959?answerId=875131022#875131022, /profile/IHadToChooseAUserNameAndIdidntWantTo'] Are there public APIs to assess notarization? [/quote] That’s tricky, because it depends on your definition of API. The codesign tool has a --check-notarization operation that does that. See Testing a Notarised Product and the codesign man page. While that’s documented, I’m not a fan of using command-line tools as APIs. The code signing requirement language has the notarized constraint. That’s not documented where it should be but it’s debatable whether that’s just because the parent document is stuck in the Documentation Archive. Annoyingly, an equivalent constraint has not been added to the LightweightCodeRequirements framework. If you think that’d be useful, I encourage you to file an enhancement request for it. And if you do, please post your bug number, just for the record. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple

Reply to Local Network permission on macOS 15 macOS 26: multicast behaves inconsistently and regularly drops
I wanted to shared a quick update on FB21858319. I figured you’d appreciate that given all the work you put in to help isolate it (-: My experience is that Apple is pretty good about fixing local network privacy problems like this one. The critical factor is reproducing the problem, which is why I’ve been so happy to get your cooperation here on this thread. Based on our preliminary analysis of your bug, we think we know what’s going on here. I’m going to offer a little insight into that below, but first I want to set some expectations. Understanding the problem isn’t the same as fixing it. I can’t offer any concrete timeline as to when a fix for this problem will be released. However, when we start seeding a beta release that contains the fix, you should be notified via Feedback Assistant [1]. As to what’s actually happening here, lemme explain a bit about how local network privacy works. As described in TN3179, the local network privacy state on macOS is per user. However, macOS’s networking stack is global

Reply to Notarization submissions stuck in “In Progress” for >24 hours (CI / REST API) – production impact
I have a standard spiel about this which I’ve included at the end of this reply. Please read it through first. With that in mind, let’s come back to your specific questions: [quote='814841021, Jackson_Hsieh, /thread/814841, /profile/Jackson_Hsieh'] Is it expected behavior for notarization submissions to remain in “In Progress” for such a long period without logs? [/quote] Yes, assuming you’ve hit the “in-depth analysis” path. [quote='814841021, Jackson_Hsieh, /thread/814841, /profile/Jackson_Hsieh'] Is client-side timeout and re-submission the recommended handling for CI workflows? [/quote] I see two common patterns reported here on the forums: Developers hit this on their first notarisation attempt, or otherwise very early in their Mac development ‘journey’. Developers have been happily notarising for a while and then suddenly bump into this. In the first case my advice is to simply wait. That’s the focus of the boilerplate text that I included at the end of this reply. My understanding is that you fall into

"Show on all spaces" toggles OFF after programmatically setting wallpaper via AppleScript
I'm building an automated wallpaper updater that fetches images from an API and sets them as desktop wallpaper on macOS Tahoe. The automation uses AppleScript combined with database manipulation to ensure wallpaper applies to all spaces. Current implementation (via Apple Shortcuts): wallpaper_path=$1 osascript -e tell application System Events to tell every desktop to set picture to POSIX file $wallpaper_path sqlite3 ~/Library/Application Support/Dock/desktoppicture.db UPDATE data SET space=NULL WHERE space IS NOT NULL; 2>/dev/null killall -HUP Dock Issue First run: Works perfectly - sets wallpaper on all spaces/desktops, Show on all spaces is ON After first run: Show on all spaces automatically toggles OFF in System Settings Second run onwards: New wallpaper only updates on the active space, inactive spaces show old wallpaper Expected: Show on all spaces should remain ON after programmatic wallpaper changes Actual: System Settings automatically disables it, breaking subsequent updates Tested work

Reply to MacOS(Apple Silicon) IOKit driver for FPGA DMA transmission, kernel panic.
Hi Kevin, filed bug number is FB21888307. I provide partial code on bug. Reply to your question: That address should have come from your driver, so how did it exceed 32 bits? All of our APIs for retrieving a bus address should either provide an address that meets your specification or fail entirely. More to the point, even if they some how did return a larger address, why/how would your driver have written a larger address when it was only prepared to handle a 32 bit address? Yes, address comes from my driver by gen64IOVMSegments API. And at the beginning, I didn't know that the address allocated through the API were always >32 bit, so when I received an address >32 bit, I didn't directly return, but continued to use it, resulting in a kernel panic. Next, the big question is how much memory are you actually trying to map? And have you done any experimentation with smaller mappings? I trying to map 20 KB memory, I have already tried 1 Byte or 4 KB, still get 64-bit address. And maximum DMA data

Reply to Background Assets: Second and subsequent download cancellations fail (iOS 26.0–26.3 RC)
Hello! That definitely looks like a problem! I think that you’re encountering two separate issues: one with download cancellation and another with internal analytics. For the former issue, we’ll try to reproduce it on our side. It would be super helpful if you could file a feedback report in Feedback Assistant, making sure to attach sysdiagnose logs from the device on which asset-pack cancellation failed soon after reproducing the behavior. Plus, filing a feedback report ensures that you’ll be automatically notified when we fix the issue. We’ll let you know if we figure out a workaround before the fix is available. Thanks! The fact that version 0 of the asset pack with the ID X-XXXXXX-XXX finished being downloaded couldn't be reported: Error Domain=NSCocoaErrorDomain Code=3851 Property list invalid for format: 200 (property lists cannot contain objects of type 'CFError') That error message concerns the latter issue. If you installed the app from TestFlight, then the system collects data abou
