Export Mac-Newbie Issue #2: Exports don´t end properly

[photopoeth]

Lightroom Version Number

14.0.1

Operating System

1. macOS 15 Sequoia

I have an issue with exporting on the Mac. The problem is twofold:
1. a maximum of 2 images get exported.
2. every export (whether up to 2 or more images) never comes to an end (you can see the process in the top left).

Here is a screenshot to illustrate:

I have started 4 exports:
1. 1 image - this was exported
2. 2 images - these were exported
3. 3 images - only the first 2 were exported
4. the missing third image from 3 - this was exported

As you can see at the top left, none of the exports are completed correctly. All processes are still in progress (for several hours).

Does anyone have an idea what is going wrong here? I get scared when I think of exports with several dozens or maybe hundreds of pictures...

BR, Thomas

You may have a "poison" image that LR thinks is corrupt. Select each image in turn and try exporting it -- does it export correctly? If it doesn't, select it and do Metadata > Save Metadata To File. Do you see an error message?

LR 13 introduce a bug (not acknowledged as such by Adobe) where Export just hangs forever when it tries to export a corrupted image.

 

[photopoeth]

OK, I´ll investigate further.
But that's probably not the reason. I tried several different exports until I documented the experiment in the screenshot.
And in this example, all images were exported, but only a maximum of 2 images in one export.

And all 4 exports don´t come to an end. But I will do some more tests. And now that I can easily restart LrC (thanks to you) it's only half as bad...

 

[photopoeth]

Ok... now I´ve done some more tests with completely random images. I tried to export 3 images each time and each time the same result: only 2 images are exported and the process hangs at the top left. I restarted LrC between each attempt to avoid side effects (

In another post you said you have a Mac Mini with 16GB of unified memory. This could be your problem. Or part of it. Unified memory means that the CPU and GPU share memory. 16GB is probably inadequate for the CPU much less being used by the GPU as well.
While Adobe says that LrC can run in 16 GB of CPU and 8 GB of GPU they do not say that performance will suffer. We recommend 32GB of RAM and 8GB of VRAM or 24-32GP of unified memory.

The other issue is working storage (free space) The export process uses lots of temporary files in working storage and if you have less than 100GB on the primary drive you can run out during the export process and the app will hang waiting for more space to create more temporary files.

Are either of these possibly the reason you cannot complete an export?

Hi.

Here´s my answers to the two possible issues you think of.

1. Memory insufficient: I have watched dozens of videos where the Mac Mini 4 Ich habe mehrere Dutzend videos geschaut, in denen versucht wurde den Mac mini M4 an die Grenze zu bringen. Darunter wurden auch LrC Im-und Exporte getestet (teilweise während im Hintergrund riesige Videos gerendert wurden), Games liefen und auch noch parallel eine Produktion mit Ableton mit absurd vielen Spuren bedient wurde. Nichts hat diesen Effekt gebracht. Ich kann nicht glauben, dass ein Export von mehr als ZWEI (!) Bildern ein Problem geben sollte. Klar, man weiß nie, aber das ist einigermaßen unvorstellbar.
Außerdem wäre das keine Erklärung, warum der Export von bis zu 2 Bildern funktioniert, aber der Prozess nicht abgeschlossen wird.

2. Working storage: I had an eye on this in the Activity Monitor (or however the correct English MacOS term is) and there´s also no problem visible. The memory pressure is always green, not even yellow.

Thanks for your thoughts.

Working storage is the fee space available on your MacIntosh HD. It has nothing to do with memory usage.

Sorry, that was a misunderstanding. When it comes to hard disk space: I haven't had enough time to fill up the internal SSD. So that shouldn't be a problem either.

 

[photopoeth]

Oops! Sorry! Ich habe gerade entdeckt, dass ich in meiner vorletzten Antwort auf Deutsch geschrieben hatte. Hier noch einmal auf Englisch:

1. Memory insufficient: I've watched several dozen videos in which they tried to push the Mac mini M4 to its limits. These included testing LrC imports and exports (sometimes while huge videos were being rendered in the background), running games and also operating a production with Ableton with an absurd number of tracks at the same time. Nothing had this effect. I can't believe that exporting more than TWO (!) images should cause a problem. Sure, you never know, but this is somewhat unimaginable.
Also, that would not explain why exporting up to 2 images works, but the process is not completed.

The second part of the answer was the misunderstanding, so I don't repeat it here.

A really silly thought perhaps, but does it make any difference where you export to? It's just top of mind because we've got someone hitting path length limits on Windows, and Adobe could have set that max cross-platform.

 

[photopoeth]

Thanks for your thoughts, Victoria. I tried to export 3 images to a folder on my desktop. The result is even worse: only one image has been exported and the process doesn't stop.

 

[Victoria Bampton]

Have you tried all the standard troubleshooting, starting with a clean uninstall?

1. Close Lightroom
2. Restart the computer
3. Use the Adobe Creative Cloud App to uninstall Lightroom
4. Restart the computer
5. Install Lightroom via the Creative Cloud App without launching any other programs.
6. Restart the computer
7. Launch Lightroom
8. Wait 5 minutes

And does the same happen if you try importing a few photos into a clean catalog and then export them from there?

 

[photopoeth]

To be honest... no, I haven't. Since the Mac is more or less brand new, the installation is only a few days old. But you're right, I should give it a try. You never know.

BTW: "...without launching any other programs" means that only CC App should be up and running. What about apps that run silent in the background (e.g. deepl, coffee buzz, privileges etc.)? Should I kill all running processes?

Good question about exporting from a clean catalog. Probably I try this first.

BR

 

[Victoria Bampton]

If the machine's brand new and a clean install, I'd try the catalog first. Also check your security permissions allow LR access to everything it needs.

The launching other programs... don't need to go crazy, it's just reducing the risk of something else interfering.

 

[photopoeth]

Ok, so using a clean catalog didn't help. Since I have to edit a shooting, I'm reluctant to uninstall/reinstall because I'm not sure if all my presets, plugins etc will work again straight away. I'll work through my editing job first and meanwhile I take the detour of exporting via Lr Desktop.

But I would be very grateful for any further ideas. Or even better... A SOLUTION!

Well... this is a good point you're making here. One big difference to Windows is the security aspect of MacOS. I'm not sure what I have to check exactly that LrC needs. There's no menu option like "grant/check all security features" or something like that.

 

[Victoria Bampton]

Oh this your first Mac? Ok, extra questions then...

1. Where's the catalog stored?
2. Where are the photos stored?
3. Where are you exporting to?

I'm particularly interested if there's an external drive involved, especially if you're running software that allows you to read/write NTFS drives or you're running a FAT formatted drive.

For security, go to System Settings and select Privacy & Security down the side. For the sake of simplicity right now, select Full Disk Access on the right and if LR Classic isn't listed there, click the + button bottom left of the right-hand panel, navigate to Applications > Adobe Photoshop Lightroom Classic and select the Classic app inside it. Then make sure it's toggled on. Restart your Mac to be sure it "took". (Theoretically you only need to give access to specific Files & Folders, but this is a really quick way of allowing access to apps that we know are safe)

GOT IT! But it's a bit embarrassing...

It was the jpegmini plugin, that I haven't had activated due to this internal error message when typing in the activation code.:
[string "JPEGminiPluginManager.lua"]:88: attempt to concatenate global 'activationResult' (a nil value) |

I have asked the support, but I've got no answer so far. I use jpegmini for my jpeg exports.It happened my PC several times that the activation got lost. But it never was a problem to export images with the deactivated plugin. It just has been ignored. BUT, obviously it's not like this on the Mac.
I had used another randomly selected export preset as a test and it worked several times. When comparing I noticed that jpegmini for was not included in that preset. I then removed it from one of the presets I was using before and now the exports worked.

LESSON LEARNED! Never transfer conclusions from PC to Mac (or vice versa)!

BTW: If anyone has an idea why the activation fails... I am very grateful for any hints.

 

[Victoria Bampton]

Excellent news! Not a clue on why it’s not activating for you though, sorry

 

[photopoeth]

Thanks! Never mind... the support is working on it.

I took a look at JPEG mini And it began with a one time purchase license but in 2020 , they went to a subscription scheme for updates. Youmay need to to reactivate on the Mac Which might need a current license and an updated version. It looks like your Windows activation did not follow you to the Mac.

 

[photopoeth]

It's working now. Support had to send me a download link to reinstall the plugin. PLUS there was an issue with System & Security. But now it is solved. Thanks for your feedback.
