In the past QLThumbnailImageCreate would return an NSImage from a url pointing to a webarchive. It's not doing so now. Is this a bug, or do I not understand something?

I submitted a version of this question 3 years ago. There has not been an answer. 662 developers are watching that question. As requested by KMT I submitted a bug report. Others had submitted a similar bug report before me. As far as I can tell, nothing has been done to address this issue. Not addressing this issue amounts to disturbing negligence. This is important! WebView is flakey. It needs to be replaced. Apple Engineering: Please accept responsibility for this issue and respond with a date when we can expect a solution.

When I shut down the mac while my app is still running, my app relaunches the next time I launch the mac. The problem is the data I had just entered into my app before shutdown is not saved as it is when I Quit the app. I'm trying to better understand this automatic relaunch of open apps so I can address this issue. Where is the documentation? What are the key words?

I'm writing a safari app extension using the default Xcode project and objective c. I want to add interface items to the popover(as Xcode has defined it with the SafariExtensionViewController.xib) and use the SafariExtensionHandler to control and respond to these interface items. I find that I can add interface items to the SafariExtensionViewController.xib. I also can connect those items to SafariExtensionViewController.h. However, SafariExtensionHandler.popoverViewController is a member of the SFSafariExtensionViewController class, the superClass of SafariExtensionViewController so I can not use this popover controller to access the outlets that I add to the SafariExtensionViewController. How can I access these interface items from the SafariExtensionHandler? ChatGPT suggest I use [SFSafariApplication sharedApplication] as an intermediary. There is no such thing. Sign!

Can macOS Safari App Extensions be purged for example in low memory situations?

I'm building a safari app extension with objective c. I'm using the default Xcode project. I've successfully added a NSView to the popover window. When I drag a NSTableView into the popover window, it appears in the XIB, but I can't find how to connect it to the SafariExtensionViewController. I tried adding a custom ViewController to the XIB and making the tableview its view which seems to be ok. How should I proceed from here, or is their another approach?

I'm trying to get the row index of a NSTableRowView that has experienced a mouseEnter event. It should be easy with rowAtPoint using NSEvent.locationInWindow. I can't get it to work. The NSTableView lies inside a NSStackView. Of course the NSStackView adjusts the visual size of the NSTableView etc. Is NSStackView interfering? If so, how should I adjust my call to rowAtPoint?
