Hi,
My app is going to consist of 2-3 pages of weather data. Do I have to add the Apple Weather logo to each page, or just the main one?
Thanks,
Dan Uff

When syncing an Office 365 (Exchange) account on an M1 Max machine running the latest macOS (e.g., Sonoma), the native contactsd and AddressBookManager processes enter a severe, persistent failure loop. The CPU usage spikes from 0.0% to over 80% (observed at 81%) and repeats every 60-90 seconds. This occurs even when the account is entirely empty of contacts and after performing a clean macOS installation, strongly indicating a systemic bug in the framework's Exchange protocol handler on the M1 architecture.
System Information
Affected Hardware: Apple M1 Max
Affected macOS Version: Tahoe 26.1
Affected Processes: contactsd, AddressBookManager
Account Type: Microsoft Exchange / Office 365
Steps to Reproduce
System Setup: Perform a clean installation of macOS on the M1 Max machine (USB boot, NO Migration Assistant or data restoration).
Account Preparation: Ensure the target Exchange account's contacts folder is entirely empty on the server (via Outlook Web Access).
Trigger: Go to System Settings > Internet Accounts and add the Exchange account. Ensure ONLY Contacts is toggled ON.
Observation: Open Activity Monitor and sort by % CPU.
Expected Behavior
The contactsd and AddressBookManager processes should spike briefly (under 5%) to establish the empty sync, then settle to a persistent idle state (0.0% to 0.5% CPU).
Actual Behavior
The processes never settle:
CPU Spikes: Usage repeatedly jumps from 0.0% to 81% for AddressBookManager and 22-59% for contactsd.
Pattern: This extreme spike lasts for a few seconds before the thread crashes/restarts, and the process immediately re-initiates the loop, consuming massive CPU cycles continuously.
Diagnostic Proof
The runaway CPU is not caused by corrupt data:
Data Neutralization: The account's contacts folder was emptied on the server, yet the high CPU loop persisted when syncing.
Clean System: The issue is reproducible on a clean, from-scratch macOS installation, ruling out corrupted user preferences or system files.
Cross-Architecture: The exact same account syncs perfectly on iOS and newer M4 Macs, confirming the data is valid and the issue is specific to the M1 Max's implementation of the Exchange protocol handler.
Workaround (For Visibility)
To restore system performance, the user must DELETE the entire Exchange account from System Settings > Internet Accounts and use a third-party client (e.g., Outlook for Mac) for synchronization, as it bypasses the buggy native framework.

We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days.
Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things.
Here are some example API calls that are giving us a 404 error now
https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US
https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US
Does anyone have any insights or information on this?
Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.
Hi Apple engineering team,
I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both:
1. Official Example
Cloned https://github.com/apple/pir-service-example
Ran PIRService locally
Confirmed that
GET /.well-known/private-token-issuer-directory → 200
GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI)
No POST /issue ever fires
2. Mock Server (Vapor)
Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries)
Verified with curl and openssl asn1parse that:
GET /.well-known/private-token-issuer-directory
Content-Type: application/private-token-issuer-directory
{ "issuer-request-uri":"https://…/issue", "token-keys":[…] }
GET /issue/token-key-for-user-token
Content-Type: application/octet-stream
<DER bytes>
Added Cache-Control: public, max-age=3600 on directory and SPKI
Stubbed POST /issue to always return { "token": "" }
Still no POST /issue request from the extension
Reproduction Steps
Install and enable a Live Lookup extension pointing to my server.
Trigger an incoming call on device.
Watch server logs—only see the two GETs, never /issue or /queries.
Expected Behavior
After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries.
Observed Behavior
Stuck in an infinite loop of:
GET /.well-known/private-token-issuer-directory
GET /issue/token-key-for-user-token
(repeat…)
No progression to the /issue or /queries endpoints.
What I’ve Tried
Verified JSON kebab-case and headers exactly match examples
Confirmed SPKI DER is valid via openssl asn1parse
Added Cache-Control headers
Tested on real device, localhost url, and ngrok public URL
Mocked a valid-looking token response
Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token?
These are the main files:
LiveLookupExtension.swift
routes.swift
service-config.json
Thanks in advance!

Its possible to add the Declared Age Range entitlement to extensions, in particular I'm looking at a Notification Service Extension.
However the DAR requestAgeRange() API takes a view controller as a parameter. Presumably therefore its not possible for a notification service extension to obtain the age range itself directly?
Yes the extension can read it from shared groups if the app reads it and set it into the group. However the scenario I'm thinking of is this:
App runs and gets the age range. Sets its functionality accordingly.
The server sends pushes which are intercepted by the notification service extension, the extension adjusts its functionality based upon what the app wrote to shared groups
The user changes the age range setting, but the app doesn't run.
The extension keeps receiving pushes but its functionality is now out of sync with the age range as its not able to obtain it directly

Is there a way to distinguish physical mouse/keyboard input from remote control mouse/keyboard input on Mac? Or even better, is there a way to detect if my Mac is being remotely controlled?
Call Screening has serious issues right now leading to missing calls from genuine callers because the system does not acknowledge them with missed call notifications or badges in a lot of cases. I'm posting this in the hope of catching an engineer who can bring this to the attention of the teams working on this.

I ran the following tests with iOS 26.1 beta 3, but the issues have been occurring on iOS 26.0 as well.
I used an iPhone, Apple Watch, iPad, and Mac for this.
The iPhone has Call Screening enabled with the option „Ask Reason for Calling“
The iPhone has call forwarding enabled to all devices.
Test 1: Active Focus
Turn on a focus like Do not Disturb on all devices.
Lock all devices.
Make a phone call to the iPhone with an unknown number.
Behavior:
iPhone: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment on devices without Always On Display.
Watch: does nothing.
Mac: does nothing.
iPad: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment.
In this test the caller does not answer any of the Call Screening questions and just hangs up. The result is that only the Mac displays a missed call notification. iPhone, iPad, and Watch do not acknowledge the missed call (no phone app icon badge, no notification, no badge inside the Phone app itself), you can only see the call inside the Calls list when manually looking for it.
Test 2: No Focus
Turn off any focus like Do not Disturb on all devices.
Lock all devices.
Make a phone call to the iPhone with an unknown number.
Behavior:
iPhone: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment on devices without Always On Display.
Watch: does nothing.
Mac: displays Call Screening UI when unlocked.
iPad: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment.
In this test the caller does not answer any of the Call Screening questions and just hangs up. The result is that only the Mac displays a missed call notification. iPhone, iPad, and Watch do not acknowledge the missed call (no phone app icon badge, no notification, no badge inside the Phone app itself), you can only see the call inside the Calls list when manually looking for it. The only improvement here is that the Mac now shows the Call Screening UI.
Test 3: Caller answers Call Screening questions
An active focus does not matter.
Lock all devices.
Make a phone call to the iPhone with an unknown number.
Once the caller answered the Call Screening questions, the following happens:
All devices ring like expected
When the caller hangs up or I don’t answer:
Mac: Shows Missed Call notification without details
iPhone: Shows Missed Call notification with transcript of Call Screening (also badges phone app icon)
iPad: does nothing.
Watch: Shows the mirrored iPhone notification.
Things to note:
When turning off call forwarding on iPhone to other Apple devices like iPad and Mac, the phone app icon is always badged for missed calls when Call Screening was active, but no notification is displayed regardless.
Hi everyone,
I’m currently developing a parental control app that uses the Screen Time API (FamilyControls, ManagedSettings, DeviceActivity). I have a question regarding the customization limits of the Shield UI in ManagedSettingsUI.
From the documentation, I understand that we can customize the ShieldConfiguration (background color, blur style, icon, title, subtitle, button labels, etc.). However, I’d like to clarify a few points before finalizing the design:
1. Is it allowed (or technically possible) to display custom media content, such as videos, animations, or interactive elements, inside a custom Shield?
2. Are there limitations on the text length for the title and subtitle fields (e.g. maximum number of characters, multiline support, truncation behavior)?
3. Can the Shield be personalized per user (for example, showing a different title or color scheme based on user preferences or device state)?
4. Are there App Store Review restrictions or UI guidelines that define what a Shield should or should not contain (for instance, whether the Shield can resemble a mini-app experience)?
I want to ensure that the implementation fully complies with Apple’s technical and design expectations before submission.
Thanks in advance for any official clarification or best practices on how far we can go with Shield customization!
Best regards,
Ferdinand
Hi,
I’m trying to open a GPX file (route.gpx) from the Files app on my iPhone using my app (e.g., Aqua Map).
Since the latest iOS update (iOS 26), when I long-press the file and tap “Open with…”, my app does not appear in the list anymore.
I’ve checked that my app has the correct permissions for Files and Folders. I’m wondering:
Is this a user-side issue (Settings on iPhone)?
Or does it require developer-side changes in the app (Info.plist / UTI declarations) to make .gpx files appear in “Open with…” or “Share” menus?
What is the proper way to make my app appear as an option to open GPX files in Files.app on iOS 26?
Thanks in advance!
In the past I was always able to install every major macOS version on an external drive so that I can test my apps. But now I'm unable to install macOS Tahoe 26 on an external drive. Actually, as far as I'm aware, there are not even official links to macOS 26 installers, but only instructions on how to update to macOS 26 from an existing macOS installation. So I thought I'd install macOS 15 on a separate drive and then update to macOS 26, but whenever I run the macOS 15 installer, tell it to install on the external drive, and reboot after the setup process completes, my MacBook just boots into my main macOS partition as if nothing happened.
3 months ago I somehow managed to install macOS Tahoe beta 1 on an external drive, I don't remember how (but I don't think it was anything crazy); booting into that beta 1 partition and trying to update doesn't work either, as my MacBook again boots into my main macOS partition. I already asked help about the update problem one month ago here, but nobody replied.
Could someone at Apple please provide instructions on how one is supposed to install macOS 26 on an external drive (if possible before it becomes available to the public)? Are we supposed to buy a separate Mac for every macOS version that we want to test our apps on?
I want to start the mail application from the development application, but the mail application made by Apple starts. It doesn't work even if I change the default email application to Outlook.
When you delete the Apple Mail app, Outlook starts. I want to automatically attach the generated pdf file to the email, but that doesn't work either.
Please tell me how to code.

Hello,
I have noticed that the ShieldConfiguration is only requested when opening a target app, and never when the application token is moved to a different shield while the target app remains in foreground.
This causes problems because many times the wrong ShieldConfiguration is displayed (recycled) instead of requesting a new ShieldConfiguration.
This bug has been around since the introduction of the Screen Time API in 2020 and is has not been addressed.
Bug reports:
FB14237883
FB17902392
Please fix asap!! Not acceptable to have bugs not being addressed for more than 5 years.
Most concerning: This is still reproducing on iOS 26 beta 7!!
Thanks a lot for your help.

I am able to block apps using FamilyControl and Shield. Unblocking is also simple—just assign nil to store.shield.applications. However, I want to unblock them even when the app is not open.
Use case: Let's say the app allows users to create a session where a particular app is blocked for a specific duration. Once the session starts, the app should remain blocked, and as soon as the session time ends, it should automatically be unblocked.
Please help me with this. Thank you!
