For 9 Glorious Months, My MacBook Pro & J5 Create JCD543 HUB Were Best Friends… Until I Updated macOS
For nearly a year, my MacBook Pro 14” (2023, M2 Pro, 16GB RAM) worked flawlessly with my J5 Create JCD543 HUB, allowing me to run:
✅ 4 External Displays (Samsung, LG, Insignia, Samsung)
A setup that worked perfectly… until I updated macOS.
Then Came the Update… and the Issues Began
First, I updated last week. Two of my four displays stopped working. No big deal, I thought—I’ve dealt with display quirks before.
Then, like an optimist ignoring red flags, I updated again last night to 15.4 Beta (24E5222f) and… well, now things are completely broken.
My Once-Perfect Setup (Now a Display Disaster)
JCD543 HUB → 2 HDMI displays (not working)
JUD380 HUB → 1 HDMI display (partially working, unstable)
MacBook HDMI port → 1 HDMI display (working, but feeling abandoned)
JCA365 USB-C to Dual HDMI Adapter (Not part of my setup, but tested—also not working)
What I’ve Tried (aka My Troubleshooting Journey)
✔ Restarted my Mac multiple times
✔ Uninstalled and reinstalled J5 drivers
✔ Swapped cables, unplugged/replugged everything, tested known-working HDMI cables (they work fine on other devices)
✔ Deleted /Library/Preferences/com.apple.windowserver.displays.plist (this fixed a similar issue in the past, but the file no longer exists in this update)
The Likely Culprit?
It seems to be a J5 driver issue triggered by the macOS update—and I’m not alone. Others are reporting similar problems.
Apple… Any Fixes?
I just want my four screens back. The setup worked flawlessly for 9 months, so it’s hard to believe it was never meant to work.
If anyone has a workaround, I’m open to testing any solution—whether it’s a driver update, system tweak, or hidden macOS setting that might bring my displays back to life.
Any advice would be greatly appreciated! Thanks in advance.
(P.S. Apple, if you’re reading this—please look into this issue!)

We are currently facing an issue with implementing "Sign in with Apple" in our iOS application built using Flutter. We've implemented "Sign in with Apple" using Firebase and On attempting to sign in, we are encountering the following error: “Sign-up not completed.”
We have verified that:
The Apple Sign is enabled on our Firebase Project.
The Sign in with Apple capability is enabled in the Xcode project.
The Apple Sign-In capability is enabled for the App ID on our Apple Developer account.
All the certificates were re-provisioned after enabling the capability.
The Bundle ID matches across Apple Developer portal and our app configuration.
The email and fullName scopes are requested in the credential.
Please let us know if you require any additional information. We’re happy to provide whatever is needed.
Here's a screenshot attached to explain the problem better
Hi there, with the latest update, the ability to click in the file name field at the top of a document (eg Pages, Numbers) to add or change the name of the file, then select filing location, no longer works. Previously, a user could do this and then hit 'return' and it would save to that location with that new file name. It no longer does this. This is a very useful functionality to have. Can it be returned in a future update?

Hi All, I searched for this feedback but didn't see it, so apologies if this has been covered by another thread. Exploring the new camera app, It doesn't seem to recognize that external storage has been connected, so the additional features that allow ProRes high frame rates will throw an error dialog stating that "to use this you need external storage" even when external storage is connected. Using the Files app, the phone recognizes the storage, and this is something I can do with this external storage device on the previous version of IOS.
It is clear that this release of the camera has been rewritten significantly since the last version. Is it possible that this is an oversight, a bug, or just functionality that has not been completed? Interested if anybody else is seeing this, or if it is just my setup.
Created an ios app and try to scan for nearby bluetooth devices but didn't manage to find my Macbook (M1 Pro, Sequoia).
How can it be done?
Trying to match the peripheral name but didn't get it.
The purpose of this is to try to see if the App can act as a FIDO2 Token to have the close proximity feature.
I'm working on an iOS/iPadOS app and need to determine programmatically whether the device is a Shared iPad as configured through Apple School Manager (ASM).
Shared iPads allow multiple users to sign in with Managed Apple IDs and are typically used in educational environments. I want to identify this configuration at runtime within my app.
I’ve looked into UIDevice, NSProcessInfo, and MDM-related APIs but haven't found a reliable way to detect whether the current device is a Shared iPad.
Is there an API or method to check if the current iPad is configured as a Shared iPad (via ASM)?
Any guidance or code examples would be appreciated.
iPadOS 26 Dev Beta 1 - need to do a restore via DFU mode. I made sure iPad in normal mode shows up in Finder and I can see device details. When I boot into DFU mode (I have kept the ipad connected to mac), it does not show up in Finder. No matter what combination of plugging/unplugging cables, rebooting, again into DFU mode, it will not show up in Finder.
Looking for steps to resolve this, or do I need to wait until beta 2 to resolve this?

Hello all,
We are in the process of deploying EAP-TLS Wi-Fi authentication across our corporate environment for both Windows and macOS devices. All endpoints are managed via Workspace ONE.
As part of our macOS configuration, we are pushing device certificates to the login keychain of managed MacBooks. For testing purposes, we have explicitly set the Access Control List (ACL) of the associated private key to allow all applications access. This includes:
eapolclient, which handles the EAP-TLS handshake for Wi-Fi
panGPS, which is responsible for establishing the GlobalProtect VPN connection (we are using certificate-based authentication with pre-logon enabled)
Additionally, we have configured and deployed a Wi-Fi profile via Workspace ONE to prevent users from having to manually select their device certificate - basically the identity preference card in Keychain Access.
Despite these settings, we are still encountering Keychain Access prompts when eapolclient attempts to access the private key. This happens even though the key is configured to allow all applications access. This behavior is unexpected, and we’re trying to understand why these prompts persist.
Has anyone encountered similar behavior on macOS, or is there something we're missing in terms of permissions or keychain configuration that could be causing this? We would greatly appreciate any insight or guidance.
Thank you,
Kyo

I submitted my ID for review over a week ago, and it's still the same, I can't log in App Store Connect?
How long have you been waiting?
Have a nice day.
updated my iPhone 15 to iOS 26 last night and now when I put the alert slider on silent, my notifications won’t vibrate. Even after checking all settings in sounds and haptics to be correct, it still isn't vibrating on silent.
Also the apple music search bar is a little flimsy? Merging the text and microphone options

Hello,
i just noticed that when i download an app through the App Store on my iPhone, the app i downloaded does not appear on my home screen or in the App Library.
is there any work around for me to make them appear at least in the App Library?
the only way to open or to place an app on my home screen I downloaded after upgrading to iOS 18.4 Beta 3 is to search for it in Spotlight or in the App Store.
Any apps I downloaded before upgrading to iOS 18.4 Beta 3 is still on my home screen or in the App Library.
i am currently running iOS 18.4 Beta 3 on an iPhone 16 Pro

Installed the iOS 26 Beta on my iPhone 13 Pro last night, hated it.
I wasn't aware that there is a supported way of restoring back to iOS18.5, so I (foolishly) opted to flash the iOS18.5 ispw file onto my device using a 3rd party tool.
Now, my device is stuck in a state between.
Unable to flash, unable to use itunes to restore, randomly gives error codes during restoration attempts.
Worries my device may be lost permanently!
Please advise.

tvOS 26 rolls out the feature to set every AirPlay speaker as permanent in the settings.
Is there a possibility to setup eARC like with the HomePods for other devices connected to a TV or will this stay a HomePod only feature?
There seems to be a broken USB sync and Finder recognition issue. Is there a fix to this?

Hello. On iOS 26 Public Beta I can’t seem to find the feature to delete a contact picture from the contacts app. It seems I can only replace but not delete. Is this just my problem?
Today I updated to iOS 26 and after changing to clear mode nothing happens, the icons remain a solid color, everything remains a solid color, nothing is transparent.
