Confirming the behaviour with

Version: 7.4.1.2 / LibreOffice Community
Build ID: 3c58a8f3a960df8bc8fd77b461821e42c061c5f0
CPU threads: 8; OS: Mac OS X 12.6; UI render: default; VCL: osx
Locale: fr-FR (fr_FR.UTF-8); UI: fr-FR
Calc: threaded


but I'm not certain that this is a bug. 

The Text.app warns the user when inserting the image file that doing so will require to converting to RTFD format, which in turn may lead to a file that isn't supported by other applications. Additionally, it seems that the image isn't stored as a copiable object with the file, rather attached somehow (at the end ?)


Honestly, I don't know how this one should be handled : RFE, copy/paste management, filter bug ?

As I wrote, being an expert on Mac clipboards, I know very well how to handle this.

The Warning is for Apps not using Apple's frameworks. This is mainly directed at MS Word, which has the same issue. That's not an excuse for LO to not fix this. (BTW, I reported the same issue to the Mac Office team but they seem to ignore it.) LO could do better than Word here.

Here's how to make a Mac app with Xcode that shows that it works, i.e. that the rtfd does indeed include the image data:

```
	// fetch 'rtfd' flavor from Pasteboard
	NSPasteboard *pb = NSPasteboard.generalPasteboard;
	NSData *data = [pb dataForType:NSPasteboardTypeRTFD];
	if (!data) {
		NSBeep();
	} else {
		// put the rtfd data into a NSTextView
		NSAttributedString *richText = [NSAttributedString.alloc initWithRTFD:data documentAttributes:nil];
		[self.textView setRichText:YES];
		[self.textView.textStorage appendAttributedString:richText];
	}
```

The only question is whether LO has a way to parse or otherwise process an NSAttributedString or the data in an NSTextView in order to convert it into its own text layout format.

BTW, I'm in the middle of setting up the build system so that I can build LO myself on a Mac and then look for myself, maybe with some help from the IRC dev channel.

This SO answer shows how to extract the images from the NSAttributedString:

So, maybe the easiest approach would be to extract the images from the rtfd, and then use the plain RTF clipboard flavor and insert the images into that.
Though, unfortunately, the plain RTF does not contain any hint where the missing image is supposed to be, it seems.

Here's an example rich text that contains "AAA\n" + image + "\nBBB\n" from the clipboard on my Mac:

{\rtf1\ansi\ansicpg1252\cocoartf1561\cocoasubrtf610
{\fonttbl\f0\fswiss\fcharset0 Helvetica;}
{\colortbl;\red255\green255\blue255;}
{\*\expandedcolortbl;;}

\f0\fs24 \cf0 AAA\
\
BBB\
}

I do not know enough about RTF to decypher it all. But there's no image reference in there, is it?

I have tried to install the dev system for LO on my Mac (running Monterey), but I eventually got a build error during `./setup check`, for which I got not help in the IRC dev channel, so I give up trying to help with this. Sigh.

Sorry to hear that. I don't know if anyone on irc builds on macOS. I encountered an issue with Ventura's SDK not being recognized and a change was pushed to deal with that, but the build setup fails anyway with a make version error. The build environment on macOS, like everything else LO related, is always one of the last of the main OSes for which LO is built, to be brought up to date. This is because the release and dev builds are based on a generally much older version of the the OS sdk so that the build will run on older versions of macOS.
