Reply to copyfile Sometimes Fails to copy .DS_Store when Copying a Folder But Does Not Report Usable Error
In the callback, I can see that the failure occurs on a .DS_Store file inside the folder. So for a .DS_Store, it is simple enough for me to just ignore the error and return COPYFILE_SKIP, but the somewhat more concerning issue here is that the true error reason is seemingly not reported? In the callback, if I read errno, it is 0. When copyfile returns, it returns -1 after I return COPYFILE_QUIT (and errno is 0), so I don't know what the error is or the appropriate way to handle it. FYI, the code to copyfile is actually open-source, so you can fairly easily find all of the places where your callback would have been called by looking for COPYFILE_ERR in the source. However: For .DS_Store, just skipping seems reasonable, but when copying a folder, it may be appropriate to get the true failure reason. ...I'd ignore all .DS_Store errors and, potentially, just skip copying them all together. The system will generate the file anytime it needs/wants to, and it's very likely that it won't consider th

Reply to filecopy fails with errno 34 "Result too large" when copying from NAS
This was always my understanding of xattrs. Yes, and I think part of what's helpful here is to not think of the resource fork as just another xattr. Its age makes it a special case. Interesting. I was using the xattr API. So just skipping the resource fork during copyfile, then running copyfile again over the src and destination (with .namedfork/rsrc convention) seems to work on my dummy test file. Is that expected to be a reliable workaround? So, the reason I keep asking the what's actually happening question is that IF this is in fact a compressed file, then just copying the resource fork won't actually work. There's an additional UF_COMPRESSED file flag that needs to be set, which then marks the file as compressed so that the system knows to retrieve and decompress the file contents when the file itself is opened. If you read through the previous threads, you can see that this flag is what ends up hiding the presence of the resource fork from the rest o

CGSetDisplayTransferByTable is broken on macOS Tahoe 26.4 RC (and 26.3.1) with MacBook M5 Pro, Max and Neo
The CGSetDisplayTransferByTable() is not working on the latest round of Mac hardware, namely the MacBook Neo (external display), MacBook M5 Pro (both built-in and external display) and possibly the M5 Max. All tested apps (BetterDisplay, MonitorControl, f.lux, Lunar) exhibit the very issue both in macOS Tahoe 26.3 and macOS Tahoe 26.4 RC. Tested on multiple Macs and installations on the MacBook Neo and MacBook M5 Pro. This issue breaks several display related macOS apps. Way to reproduce the issue using an affected app: Install the app BetterDisplay (https://betterdisplay.pro) Launch the app, open the app menu, choose Image Adjustments and try to adjust colors. Adjustments take no effect Way to reproduce the issue programmatically: Attempt to use the affected macOS API feature: https://developer.apple.com/documentation/coregraphics/cgsetdisplaytransferbytable(::::_:) Here are the FB numbers: FB22273730 (Filed this one as a developer on an unaffected MBP M3 Max) FB22273782 (Filed from an affe

Screenshots not uploading
I've been struggling for days to upload screenshots to App Store Connect. The Chrome console is showing multiple upload errors with status 0. One screenshot did sneak in and did upload, but every one I upload just fails without any messages. It will stick around with a gray box and cloud icon saying the file has not uploaded yet. I've seen multiple online posts from the past suggesting waiting (I waited 2 days), trying different browsers, private mode, resaving the image, etc.. I've never had this issue in years of uploading screenshots to App Store Connect. I really think this has to be an issue on App Store Connect but their status page doesn't show anything. Is anyone else having this issue?

Reply to How to monitor heart rate in background without affecting Activity Rings?
Thanks for doing the thorough test, and sharing your test result, which is very well-written. The details unveiled in the result is definitely very helpful. Just to confirm that, other than an active HKWorkoutSession, there is no API that can trigger high-frequency heart rate sampling. Also, thanks for filing the feedback report.

Reply to good morning My app has been approved and in the app store but my subscriptions are not working
Hello - In order to resubmit your three IAP subscription products, the status of each needs to change from Developer Action Needed to Ready to Submit. We recommend editing each of them, in order to save an update (e.g.: add a note to the Review Notes section like [Date] Updating IAP to resubmit with new binary of Version 1.x of [App Name]. Once the status of the IAPs has been successfully updated, proceed to submit a new version of the app - and attach the three IAPs for review as documented here under Submit an In-App Purchase of the first time. If you are still unable to resubmit the IAPs with a new app build, please file a detailed ticket (including screenshots and/or video) via Feedback Assistant, and reply back to this thread with that ticket number - and we will follow-up. Thank you.

Just read your reply again more carefully as it is not the end of the day and I'm not tired :) . As the thread up above shows, the primary way to bypass the issue copyfile is having is to use the ..namedfork/rsrc convention, Interesting. I was using xattr API. So just skipping the resource fork during copyfile, then running copyfile again over the src and destination (with .namedfork/rsrc convention) seems to work on my dummy test file. Is that expected to be a reliable workaround? I guess if this actually works reliably I wouldn't have to restart copy from scratch or suppress deprecated API warnings. Or maybe there good reason to start the copy from scratch with the Carbon file manager?

Reply to SFCC Integration: onpaymentauthorized Not Firing After Touch ID Authentication (Apple Pay on the Web)
Thank you for the thread attached in your response. The issue faced above internal to the Salesforce B2C Commerce Business manager configuration. We are working for a US based site where 3DS is optional for merchants. Hence we did not enable it in our Business Manager portal. Later, we found that 3DS is mandatory for Apple Pay to work. Below is the documentation shared by Salesforce with us. https://developer.apple.com/documentation/applepayontheweb/applepaypaymentrequest/merchantcapabilities This information is neither logged in the browser console nor in the server side logs as there was no authorization event being triggered from applepay.js file hosted on Salesforce B2C Commerce instance. This has become a grey area for us to reach out both Apple and Salesforce. After enabling 3DS, we are seeing the authorization event triggered. Hope this answer helps for others who face similar issue on Apple Pay on Salesforce B2C Commerce aka Salesforce Commerce Cloud (SFCC) formerly known as Demandware.
