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!)

I updated my Macbook Pro this week, macOS Sequoia 15.3.2 and now the Password app isn't working. When I log into my regularly saved sites, and I click user name, the Password app login modal pops up, but when I click it, NOTHING happens. If I manually type in my user name (which was unnecessary prior to the recent update), then SOMETIMES I get the fingerprint, but most times I don't. I am using the Chrome browser. I have attached a screenshot of the typical issue I experience.

We are currently listening to App Store Server Notifications V2 and have encountered an issue with notification ordering.
Specifically, there are instances where Apple sends the DID_CHANGE_RENEWAL_STATUS notification before the INITIAL_BUY notification. This leads to a situation where we are unable to process the cancellation of a transaction that is unknown to us at the time of the renewal status change.
Could you please clarify why this occurs? If this is a bug, could you kindly address it and implement a fix?
Below, I have included examples that illustrate the issue. These examples I obtained using the Notification History API, which may help in troubleshooting.
bundleId: com.picsart.studio
case 1:
originalTransactionId 350002410***633
DID_CHANGE_RENEWAL_STATUS - ‘2025-03-05T00:47:05.900Z’
INITIAL_BUY - ‘2025-03-05T00:47:40.728Z’
case 2:
originalTransactionId 420002297***345
DID_CHANGE_RENEWAL_STATUS - ‘2025-03-03T11:43:54.006Z’
INITIAL_BUY - ‘2025-03-03T11:43:56.437Z’

在使用xcode15.2与iOS14.2版本的手机进行调试时,发现OC编译的sdk无法正常传输数据给swift编写的项目。当我的手机连接xcode调试的时候,数据能够正常传输、转换。当我断开手机与xcode的连接的时候,就无法正常获取数据了。而这个问题目前我只发现在iOS14.2中。当我使用iOS17与iOS18手机调试时没有出现这个问题。请问有没有人遇到过相似的问题。
Issue with Heart Rate Graph from Apple Watch in iOS App
Hello Community!
I hope everyone is doing well. I'm developing an iOS app that includes a feature to display a graph of the heart rate recorded during a route using the Apple Watch.
Current Implementation
I have successfully implemented data collection and transfer from the Apple Watch to the iPhone.
The app's main UI correctly displays the user's real-time BPM.
When the user stops the route, an analysis view is generated, showing speed and altitude (both work perfectly).
Expected Behavior
The user starts recording a route while monitoring heart rate.
After tapping "Stop Route," an analysis view should display a heart rate graph along with speed and altitude data.
Issue Encountered
Despite multiple attempts, I have not been able to properly generate the heart rate graph.
The only result I have achieved so far is a flat line with points representing the recorded BPM over time, instead of a proper graph.
Request for Help
If anyone has experience implementing a similar feature, I would appreciate any guidance on correcting my implementation.
I can share:
The file responsible for graph visualization.
The file handling data processing after the user stops the route.
Any help or suggestions would be greatly appreciated!
Summary
I'm trying to display a heart rate graph from Apple Watch data in my iOS app. While data collection and transfer work fine, the graph only shows a flat line instead of a proper visualization. Speed and altitude graphs work correctly. If anyone has experience with this, I’d love some guidance!

My main app is CardView based w/programmatic navigation.. My secondary app is a nice EventListView w/programmatic navigation. Both are functional with no errors.
I want to add an event list to my CardView app but the appearance is all wrong. See image. The blue swirl at bottom is all of my List that appears.
I can post images of code, if needed.
My question is this - can I combine CardViews and ListViews?

Too many irrelevant posts come up when I attempt to search for something. There should be an easy button or something to earmark posts as something irrelevant- something that shouldn't come up in a search. I'm looking for something in Xcode 15 and frequently the top posts in the search are 10 years old and don't have any relevance whatsoever to the solution to my problem.

Since running 18.4 beta 3 my phone doesn’t stop charging at its pre determining %
it’s set at 80% and until now has always held at that percentage but since installing beta 3 it’s gone to 100% and held at that when charging overnight
anyone else experiencing this?
So, I was attempting to rename my Finder Tags. Unfortunately, I’m also trying Apple’s Intelligent Writing Tools to proofread it, but I’ve encountered a bug in it. Here’s an example:
For reference, my macOS version is macOS Sequoia 15.3.2 (24D81)—a stable version.
I hope that bug is fixed soon.
Apple announces a Japanese game (Assassin's Creed) in Japanese in Japan but then states "the App is currently not available in your country or region"... that is, Japan!
https://developer.apple.com/jp/news/?id=q2zte70j
Game is unavailable so why announce it?
I see games like Resident Evil and others have a partnership with Apple to help bring it to the MacOS and iOS platform and I was wondering if anyone knows how a company gets these partnerships, is it Apple who reaches out or do they have to reach out?

Dear Apple,
I am sending this review to tell you that with my new update. I am not a fan of the photos set up. I find it very confusing and find myself getting irritated very often and giving up after searching for an image… which is frustrating for many reasons including I need my camera roll for work often. please make adjustments with the newest update… please.
thank you, if anyone took the time to read this.
Ashton, a very sad customer

Hi,
Am using fastlane to upload into TestFlight. Am able to successfully upload the build without any issues.
For Testing Internally , I want to upload the build into App Store Connect but I should restrict it on submitting to App Store. ( This is possible when i distribute the app via TestFlight Internal Only from XCode -> Organizer -> Distribute App (Select option with TestFlight Internal Only). I want to achieve the same using either Transporter/ fastlane.
I tried setting buildAudienceType to INTERNAL_ONLY as per https://developer.apple.com/documentation/appstoreconnectapi/buildaudiencetype but it is not working.
Can you suggest how i can achieve this via fastlane?
