Unable to Save Edited Word Files After Installing macOS 26 Beta on MacBook Air M3
Hello, I recently installed the macOS 26 beta version on my MacBook Air M3, and I've encountered an issue where edited Word files are failing to save. I’ve tried restarting my laptop and checking for updates, but the problem persists. Has anyone else experienced this issue? Is there a specific setting I might have missed or any troubleshooting steps you recommend? Thank you for your assistance!

Which iPad gen device I should purchase, where AppStore is rejecting my app for iPad Air gen 5
Recently I got an issue on App Store that my build got rejected because of iPad Air 5. My app include Device binding which means sim should be present in Device while using the app, where as, I mad the app mainly for iPhone not for pads. But AppStore is rejecting my build saying getting no sim issue in iPad Air 5th gen And os 18.5 . So what should I do? Which device I should prefer so that I can use it future also , should not be outdated within some time.

Example for AccessorySetupKit bluetoothTransportBriding
Hi there! I'm developing a dual-mode bluetooth accessory and would like to pair it through AccessorySetupKit. I'm using an ESP32 with Bluekitchen btstack. This supports CTKD, which seems to be a requirement for the Bluetooth transport bridging according the WWDC19 session 901. I've been in contact with the btstack developer and verified that I can get the device to generate an LTK for the classic transport when reading an encrypted attribute. I'm not able to get this to work with the bluetoothTransportBriding option with AccessorySetupKit though. What I've found so far is that if I omit the .bluetoothTransportBriding option during pairing I will get a pairing request when I read an encrypted attribute after connecting with the CBConnectPeripheralOptionEnableTransportBridgingKey option. If I accept this request it seems like the system automatically brings up the A2DP profile. However if I include .bluetoothTransportBriding and/or .bluetoothPairingLE this option does not pop up, but the system does not bring up the A2DP profile. In this case things seem to end up in a weird situation where the device doesn't show up for pairing in Bluetooth Settings either, making it impossible to manually connect for A2DP. Based on the AccessorySetupKit example from WWDC24 I've created a dice accessory firmware for ESP32 using btstack. The code for this is available here: https://github.com/ljodal/esp32-btstack-ctkd-test I've also tweaked the AccessorySetupKit example app for iOS to add the ASAccessory.SupportOptions. The code for that is available here: https://github.com/ljodal/accessorysetupkit-ctkd-test Is there any documentation available anywhere on what is expected of the device for Bluetooth Transport Bridging to work with AccessorySetupKit?

What kind of feedback is available through tvOS Bluetooth HID?
first post here and this is kinda a long shot. I’m working on a custom keypad project for a young man with some mobility issues that unfortunately prevents gestrue and voice control as UI options. id like to see if I can pull track metadata via a Bluetooth connection into a custom keyboard with a small screen. I know hid doesn’t support this but I was hoping maybe the API for iOS’s blueprint remote app could be leveraged. I haven’t don’t much with Apple previousl. Usually Roku and Crestron implantations but I’m hoping to see if I can accomplish something with Apple, without needing to implement any IP connection.

The local network connection suddenly fails
Our app is connected to a hardware wifi without network. Under normal circumstances, we can communicate with the device. At some point, the communication suddenly stops, and the ping prompts "No route to host". The only way to reconnect is to restart the device. It feels like the system has marked ARP. Is there any way to reconnect the device without restarting the iphone?

iPadOS26 beta4 Tap Judgement
On the iPad Pro 12.9-inch (3rd generation) cellular model, when you touch the screen with four fingers and then move your fingers, the touch is no longer detected. The same operation with one to three fingers works normally. This phenomenon does not occur when accessibility is turned on. Is this a beta-specific issue that will be fixed in the official release?

isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method cannot determine whether the camera is available, please provide an available judgment method
Prerequisite: After the MDM APP issues the command, the camera on the phone is no longer visible (unusable). After upgrading to iOS 26.1, the isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method keeps returning true when the camera is unavailable. The isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method on iOS 26.0.1 is normal, returning false when the camera is unavailable and true when it is available. Please fix this method to determine If the isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method cannot determine whether the camera is available, please provide an available judgment method.

Not Getting Realistic Camera Output Even After Capturing RAW (.dng) Images on iOS
Hi everyone, I’m working on a custom camera implementation in iOS using native code. My goal is to capture unprocessed, realistic images directly from the camera — without any filters or post-image processing applied by the system. I’ve implemented RAW image capture using the native camera APIs (AVFoundation) and successfully received .dng files. However, even the RAW outputs don’t look like the real environment — the colors, tone, and exposure still seem processed or corrected in some way. I’ve tried various configurations such as photoSettings.rawPhotoPixelFormatType, experimenting with AVCaptureDevice and AVCapturePhotoOutput settings, and reviewing ProRAW and standard RAW behavior, but I’m still not getting truly unprocessed results that reflect the actual sensor data. Has anyone experienced similar results when capturing RAW images on iOS, or found a way to bypass Apple’s image signal processing (ISP) pipeline for more realistic captures? Any insights or references from Apple’s camera framework behavior would be greatly appreciated. Thank you!

2.1.0 Performance: App Completeness
Hi everyone, I submitted an app for review and was met with a rejection for unresolved issues. This was what was asked in the rejection: Provide detailed answers to the following questions: -Does your app interact with any hardware? Would that be referring to the camera/microphone of the device? My app uses haptics when you select an option. I didn't see anything in connect where I needed to specify the use of haptics. Also, does this mean that when the reviewer answers me I have to resubmit as a version 1.1? I'm not sure what I would need to change. This is my first app so I'm not entirely sure on the procedure.

help getting audio verbs macOS Tahoe Deep Debug Logs
Im running macOS Tahoe and I have the proper nvram boot-args , however when I try to poke the log stream im not getting any verb information related to the card im using. The audio system im using is AppleHDA.kext from the Beta 1 KDK. I've tried asking AI it doesn't make a difference what it suggests to me..... In the meantime of while im asking for assistance what ill do is go ahead and let it template me a kernel extension that I guess just traffics it to the Log for me and hopefully this isn't filtered out as what I suspect is it saying is happening is is that it actually masks some of the information. Why am I doing this? not For the Linux Driver its so I can see from the Log where it came from as this is what the developer said he did GitHub/davidjo/snd_hda_macbookpro is the kabylake iMac.

Misclassifying external medical device.
We have an app that connects to an external device that we developed in-house that measures electroencephalography (EEG), as well as PPG and IMU. This is not a medical device and we have stated that many times but the app review process keeps rejecting the app for the same reason 1.4.1 - Safety physical harm because they say it is connecting to a medical device. We have submitted documentation for FCC certification for safety but we do not have FDA certification because it is not used for medical purposes - purely wellness. Despite several messages explaining it is not a medical device the response is always the same without actually addressing any of the supporting documents we have sent. Any help to find a way to explain to the Apple team that not all EEG devices are medical and in fact most are NOT FDA approved would be appreciated as it seems like whoever is reviewing the app doesn't understand that.
